FAQ

It is a great idea to know the similarities of all hearing aids before trying to judge the differences.

There are four primary similarities with all hearing aids: A speaker, a microphone, a battery and an amplifier. No discredit to all of the hearing aid companies out there but at the end of the day, their product is simply some combination of these four things.

There are five principle styles that all hearing aids are designed around.

1.Open fit(OF or RIC) – these leave the ear canal open and are really best for people with light to medium hearing loss.

2.In the ear(ITE) – the most common fit – these fill the ear canal and are good for those with severe hearing loss.

3.Behind the ear(BTE) – these hearing aids provide the most power and are almost a necessity for people with severe hearing loss.

4.In the canal(ITC) – good for mild to severe but not ideal for people who are not very good with small knobs and buttons.

5.Completely in the canal(CIC) – these are perfect for medium to mild hearing loss. They are small so they don’t get wind disturbance at all but the smaller batteries lead to more frequent changing.

The five main hearing aid styles are interesting to consider. From afar hearing aids can all seem similar. Far from it. There are many distinctions.

Earplugs and ear contact area is strictly closed, the amplified sound is leaked from the cracks and returned to the microphone to enlarge to produce the whistle. This phenomenon is similar to our common howling that the microphone close to the speaker.

       (1) The hand or an object close to the hearing aid, due to a part of the sound-reflecting in your palm or the object and returns to the microphone to further amplified.

        (2) The hearing aid is not completely inserted into the ear canal or not tight seal with the ear canal wall, the amplified sound leaks and returns the microphone.

        (3) A lot of earwax in the ear, due to the earwax embolism, the amplified sound reflections to the earwax again and to the microphone, can also generate a feedback.

Not all hearing loss can be corrected through the use of hearing aids or alternative listening devices. The type of hearing loss determines the specific treatment required.

There are four types of hearing loss:

1.Conductive: This could be caused by something as simple as earwax buildup!

2.Sensorineural: This is caused when tiny hairs in the cochlea are missing or damaged.

3.Mixed: This is a combination of conductive and sensorineural hearing loss.

4.Central: Strokes and central nerve diseases are often the cause of this type of hearing loss.

Recently, in the Europe and the United States Hearing Aids market, a new high-tech product called mini RIC hearing aid has become the newest category of hearing aids with the fastest growth in demand. From pocket hearing aids, BTE hearing aid, ITE hearing aid to this mini hearing aids (RIC hearing aids), this may be one of the most revolutionary innovations in the history of hearing aids industry.

Moreover, there are some reasons why is the RIC Hearing aids for users:

1.The Ric hearing aid body is more smaller than the regular BTE Hearing aid because of the Ric hearing aid receiver is in the ear canal not in the hearing aid body,so the Ric hearing aids are more discreet and invisible than the BTE hearing aid.

2.The Ric hearing aids have the thin running wire connected the receiver,it is more beautiful than the BTE hearing aid with the tube.

3.The Ric hearing aids receiver are more closer to the tympanic membrane, so the sound is more natural and clearly.

4.the RIC hearing aids Receiver with a special anti-earwax device to make the wearer feel more comfort and reliability when using the hearing aid in humid environments.

According to the different requirements of Users on hearing aids, we can classify these Users into three groups as per their needs:

The 1st group: Need hearing aid to hear clearly, no requirements on the appearance, the price is cheap and can work for talking.

The 2nd group: Need hearing aid to small or invisible and beautiful, meanwhile the sound quality should be OK at certain requirements, but they can tolerate the hearing aid wearing discomfort to some extent.

The 3rd group: Need the hearing aid comfortable, clear, beautiful appearance. This group of Users’ needs will be the main customer of RIC hearing aid.

One of the most common "myths" about hearing loss is that only "old people" suffer from it! In fact, the reverse is true! The majority (65%) of people with hearing loss are younger than 65 and six million people in the U.S. between 18 and 44 suffer from hearing loss (Better Hearing Institute website).

The truth is that there are several causes of hearing loss with "exposure to noise" ranking high among the reasons.

The primary causes of hearing loss are six ways as follows:

·*Exposure to noise

·*Family history of hearing loss

·*Medicine

·*Aging process

·*Disease

·*Head trauma

 Please refer to the table as details in Decibel (dB) below:

If you answer yes to several of these questions, you may need to get a hearing test:

-Is it hard to hear or understand others?

-Do you get frustrated trying to hear things?

-Do people get frustrated because they need to repeat what they say to you?

-Do you turn up the TV or radio louder than those around you would like?

-Do you have trouble hearing what people are saying in restaurants or at the movies?

-Is your social life, school, or job limited by your problem with hearing?

You might think the voices are not real and clear enough for the first using. Because you Have become accustomed to the original hearing status. You would heard some unfamiliar voice for the first using because haven't adapt yet. The main way to solve this problem is make some necessary adaptive training, beginning time not too long, the volume is not too large, slowly adapt.

Hearing aid adaptation training is not complicated, the general principle is to adhere to wear, step-by-step adapt:

    (1) The daily wearing time should be from short to long;

    (2) The volume adjusting should be from small to large;

    (3) The communication environment should be from quiet to complex, from simple complexity.

    So step by step adapt, in order to make you as soon as possible to through the adaptation period, and make the role of hearing aids to maximize.

Hearing aids come in different shapes and sizes but work in a similar way. They have a built-in microphone that picks up sound, which is processed electronically. The resulting signals are then passed to a receiver – like a tiny loudspeaker – where they are converted into louder sounds that you can hear.

Hearing aids will help you hear everyday sounds like your phone and make it easier to follow conversations. You may also be able to enjoy listening to music, the TV and radio again.

If you have tinnitus, you may find it disturbs you less when you wear hearing aids.

In brief,the hearing aids can:

1.make sounds louder

2.make conversations easier

3.help you hear on the phone

The answer is surely YES,the hearing loss impacts all aspects of our life

Hearing plays a major role in our quality of life, from our emotional well-being and physical health to our careers and leisure activities.

Firstly, Hearing loss impacts our emotional well-being

When we hear our best, there’s nothing stopping us from enjoying the sounds of laughter, music, nature or conversations with family and friends. Hearing these sounds help fuel us, and undeniably make moments more memorable and life more enjoyable.

But,when hearing is impaired, those sounds we've taken for granted fade — leading to a cascade of changes that could impact us emotionally, such as:

1.Hearing loss might cause embarrassment

2.Missing favorite sounds might lead to sadness

3.Missing critical information could create anxiety

4.Not hearing conversations clearly might lead to feeling left out

5.And feeling left out can lead to depression and social isolation

Secondly, Hearing loss impacts our physical and mental health

When hearing is impaired, our sense of space shrinks, warning cues get missed, and we withdraw from social activities or situations.

This leaves our physical and mental health vulnerable,saying:

 -Adults with hearing loss are up to 5 times more likely to develop dementia

 -Hearing loss is linked to a three-fold risk of falling

 -Accidental injuries are up to 50 percent more likely for people with hearing loss

Thirdly, hearing loss impacts everyday life

When hearing is impaired, those connections, interactions and moments can be muted and strained, which has an impact on our quality of life,including:

+Missing a grandchild's first words or a family dinner story

+Feeling left out of a conversation or a good joke

+Limiting once-fun social activities

+Feeling less independent, less confident and less secure

+Frustrating loved ones with constant requests to repeat what was said

+Not living life to the fullest because hearing loss is holding you back

The symptoms of hearing loss can vary depending on the type of hearing loss, the cause of hearing loss, and the degree of loss.

In general, people who have hearing loss may experience any or all of the following:

1.Difficulty understanding everyday conversation

2.A feeling of being able to hear but not understand

3.Having to turn up the TV or radio

4.Asking others to repeat often

5.Avoidance of social situations that were once enjoyable

6.Increased difficulty communicating in noisy situations like restaurants, lively family gatherings, in the car or in group meetings

7.Tinnitus, or ringing and/or buzzing sounds in the ears

“Which hearing aid is best for me?”here,you can learn what to consider when choosing a hearing aid.

As someone with possible hearing loss or having a history of wearing hearing aids, you may have mulled over the decision to buy new or buy again more than once. But, we humans tend to be fickle and possibly presumptuous about placing a plastic device inside our ears for an extended time. We may worry about how the hearing aid will look once fitted or if it will really help with our hearing loss. But understanding our anxiety can help when we go to research what to look for when purchasing a hearing aid — and this may relieve some of our concerns.

For the most part, hearing aids come with fundamental parts that transfer sound from the environment around you into your ear. The contention may come when we start to decide or research the number of different hearing aid styles available to us, which can vary in size, shape, and the way that they are fitted onto or into your ear. Some hearing aids are small enough to go inside the ear canal, which allows them to be barely visible — or what popular terminology refers to as invisible hearing aids. Other hearing aids only partially go inside the ear canal; thus, these are more noticeable to the eye. On average, the smaller the hearing aid, the less power it may output given its engineering for a smaller form over total power output. A smaller hearing aid might also have shorter battery life and because of its precedence on being small, it may cost us more.

Here are typical hearing aid styles you might find almost anywhere:

1.Completely in the Canal Hearing Aids (CIC)

Completely-in-the-canal hearing aids are molded to be fit inside the ear canal and generally improve mild to moderate hearing loss in adults.

2.In the Canal Hearing Aids (ITC)

In-the-canal hearing aids generally are custom molded and are fitted partially in the ear canal, but may not go as deep as the completely-in-canal hearing aid. This hearing aid is also sufficient for mild to moderate hearing loss in adults.

3.Half-Shell Hearing Aids

Half-shell hearing aids are usually smaller versions of the in-the-canal hearing aid. They are custom molded and generally fit into the lower portion of the bowl-shaped area of your outer ear. These are appropriate for mild to moderately severe hearing loss.

4.In the Ear or Full-Shell Hearing Aids (ITE)

·  Noticeable to others because of its larger size and fit.

·  May occasionally pick up more wind noise because of the aforementioned size.

·  Easy to adjust and has easy-to-use features such as volume control.

·  Easier to use and insert into the ear.

Behind-the-ear hearing aids are able to “hook” over the top part of your ear and rest behind the ear. This hearing aid picks up sound, amplifies it, and transfers that sound to an ear mold that goes inside your ear canal. This hearing aid type is appropriate for almost any type of hearing loss — and it is consider for most ages as well.

Behind-the-ear hearing aids offer the following benefits:

·  The largest size and most visible to the eye; however, newer versions try to streamline the bigger size.

·  Amplification capabilities that are stellar and provide high output volume.

6.Open Fit Hearing Aid

Open fit hearing aids are primarily very small behind-the-ear style hearing devices. Larger behind-the-ear hearing devices can also be augmented to a more open-fit style. Sound is transmitted through a small tube or wire to a dome or speaker in the ear canal. These hearing aids leave the ear canal open, so they are better and more suited for mild to moderate high-frequency hearing losses whereas low-frequency hearing is still normal or near normal.

1.Completely in the Canal Hearing Aids (CIC)

Completely-in-the-canal hearing aids are molded to be fit inside the ear canal and generally improve mild to moderate hearing loss in adults.

Completely-in-the-canal hearing aids offer the following characteristics:

·  Barely (if it all depending on the situation) noticeable in the ear; thus, helping out those with concerns over general appearance of the hearing aid in the ear

·  More resistant to wind noise because of its placement inside the ear canal.

·  Convenient to use with telephones generally.

·  Employs a smaller sized battery because of its design, which may not last as long as others.

·  Might not have an exhaustive feature set because of its smaller design; features reduced may be volume control or directional microphones.

2.In the Canal Hearing Aids (ITC)

In-the-canal hearing aids generally are custom molded and are fitted partially in the ear canal, but may not go as deep as the completely-in-canal hearing aid. This hearing aid is also sufficient for mild to moderate hearing loss in adults.

In-the-canal hearing aids offer the following characteristics:

·  Not as noticeable in the ear; thereby, the look is proper attire for many who are concerned with how the hearing aid looks when fitted.

·  Still convenient to use with the telephone.

·  Includes extra features that the completely-in-the-canal hearing aid might not offer.

·  The smaller form of this hearing aid may pose a difficulty when trying to adjust certain things on it.

·  May be troublesome to users with smaller ears.

The hearing ability declines gradually with aging called the aging deafness

The features of aging deafness:

1. Appear after reaching a certain age, without clear reasons, Happening and developing unconsciously by a certain age with no definite reasons.

2. Hearing loss showing as sensorineural hearing loss with high frequency decline.

3. The results of the speech hearing test are abnormal, much more serious than the pure tone hearing test results.

The main aging deafness performance:

1. It can't hear talking sound or can not hear the sound of the phone and the doorbell clearly.

2. It is difficult or obviously difficult to answer the call.

3. When watching TV and listening to the radio, the sound is too small to hear, and the sound is loud and noisy.

4. It is possible to talk to people and children who are familiar with them in the early days. But it is difficult to talk to unfamiliar people. There are obstacles to talking with all people in the later stage.

5. In a quiet environment, it is good to talk to people, but it is difficult to work in a noisy environment, especially in group activities where there are many people.

6. Most people are accompanied by tinnitus or cranial sound, especially in a quiet environment.

"I can hear, but I don't know what I'm talking about" is a common complaint of many sensorineural deafness patients, even after they have the right hearing aids. Why is that?

Compared with normal hearing, sensorineural hearing loss patients not only have the problem of volume reduction, but also have the problem of frequency distortion (poor frequency resolution). Some words that are light in pronunciation may not be heard at all. Although all sounds can be heard with hearing aids, it is still impossible for the patient to hear every word clearly, especially in noisy environments. This is because, although correctly compensated by hearing aids, patients still have the following problems: poor time resolution; poor frequency resolution; poor intrinsic noise reduction.

In noisy environments, people with normal hearing can't hear because the sound signal itself becomes ambiguous; a similar situation can occur when the signal is too small. For example, the television is too small for our normal hearing to hear. But this is not the whole problem.

The inner ear has the ability to analyze acoustic signals. If the inner ear is damaged, the ability of auditory analysis will decrease significantly. But because we have enough room for hearing discrimination, we don't have to listen 100% to make sure we understand. Therefore, less serious inner ear injury does not make the patient completely deaf.

Our ears are complex sensory organs. They have many small, sensitive sensors to pick up sound waves, bundle them together, and send them at lightning speed down our auditory nerves towards our brains. In order for the auditory centers of our brains to translate those acoustic signals into sound, music, or vitally important warning signals reliably, the sound must not be disturbed or interrupted on its path through the ear.

The Journey Through The Ear.

When we talk about our ears, we’re usually referring to the part that’s visible from the outside. But that’s not even half the story. In fact, that part is just the auricle. A much larger part of our hearing systems is safe within the protection of our heads. Follow the sound on its journey through our ears.

The Outer Ear.

The first stop on the sound’s journey is the outer ear, which receives the sound and directs it through the auricle into our heads. Numerous little peaks and valleys act as a resonator to amplify the vibrating air. At the end of the entrance to the ear, the sound waves hit the eardrum, a thin membrane separating the outer ear from the middle ear.

The Middle Ear.

From the eardrum, the subtle vibrations are transmitted to three tiny ossicles—the smallest bones in the human body. The hammer, the anvil and the stirrup are arranged in such a way that the sound gets amplified by a factor of 20 before being directed into the inner ear.

The Inner Ear.

In the inner ear, the sound waves encounter the next membrane, which is called the oval window. From there, they travel to the equilibrium organ on one hand, and the cochlea on the other. The cochlea is made up of three channels filled with fluid. The sound causes tiny hair cells on the bottom of these channels to vibrate, which converts the mechanical sound waves into electrical nerve impulses. Depending on how high the frequency of the sound is, this wave movement is shifted, which shifts the place in the cochlea that reacts most sensitively to that frequency: high sounds trigger the hair cells at the front of the cochlea; lower sounds activate the ones further back. From there, the impulse is transmitted to the auditory center of the brain.

When fitting the hearing aid for the people all men and women who have hearing loss problem,there are the same question that is it necessary to wear two hearing aid for both right ear and left ear?Here,the Great EarsMate,a hearing aid experts give you the answer is YES,it is necessary to wear two hearing aid for both right ear and left ear.

1.Improved speech understanding, especially in noise

The brain receives auditory input from both ears. As the brain interprets sound, it uses information from both ears to distinguish between noises such as background noise and speech. If the brain receives data from one side and not from another, it can misinterpret what is heard.

Research shows that most listeners who wear two hearing aids have an easier time understanding speech in the presence of background noise.

2.Improved sound localization

Sound localization refers to the ability to determine where a sound originates. Two hearing aids receive sound from both sides of the head and transmit the information to the brain. If the sound signals are always louder through one ear, the brain has more difficulty identifying the source. However, if the brain is able to compare the relative loudness of what is heard, it can more easily and accurately determine the location of the sound.

3.Improved sound quality

Two hearing aids allow the audiologist to lower the volume for both aids. This promotes the audibility of soft sounds while limiting the distortion of louder sounds. It also promotes a sense of auditory balance, fullness, and clarity.

An estimated 10 dB of additional gain can be added to promote the overall enhancement of sound quality when two hearing aids are worn.

4.Reduction in the annoyance of tinnitus

When tinnitus is caused by hearing loss, hearing aids can be used to manage its symptoms.

Firstly,let's introduce something about the OTC Hearing aid as following:

Over-the-counter (OTC) hearing aids (or OTC wearable hearing devices as recommended in the NAS report noted below), are not yet approved by the FDA. They would be hearing devices for adults with mild to moderate hearing loss purchased directly by consumers from a retailer or online. OTC hearing aids will be regulated by the Food and Drug Administration (FDA) with clear labeling as to use, safety and efficacy. This would be a new option to allow adults with mild to moderate hearing loss to get affordable and easily accessible hearing aids.

Then, please learn something more about the PSAPs here:

PSAPs (Personal Sound Amplification Products) are amplification devices available now that are intended only for those with normal hearing. The Food and Drug Administration (FDA) prohibits manufacturers of PSAPs from marketing their products as hearing aids to people with hearing loss. One example of how PSAPS are marketed is for hunters who want to hear deer in the woods. PSAPs should not be confused with OTC devices. OTC hearing aids or OTC wearable hearing devices are a classification that the FDA must approve before they will become available to consumers.

Why Is HLAA Supporting OTC Hearing Aids?

The NAS has made a clear, evidence-based case that OTC hearing wearable devices should be available for adults with mild to moderate hearing loss. A bill has been introduced in Congress called the Over-the-Counter Hearing Aid Act of 2017 and HLAA supports the bill.

An estimated 86 percent of people who would benefit from hearing aids do not get them, primarily because of high cost.

HLAA believes and OTC hearing aids will provide accessible and affordable hearing health care to millions of people who might not otherwise seek help. Or, for those who have sought help, OTC hearing aids could provide an affordable option.

People usually wait seven to ten years before they seek help. By that time, hearing loss has totally disrupted their lives, impacting their communication at work, with their families, their ability to participate in their communities and in activities that give their lives meaning and fulfillment.

We believe that available, affordable and accessible OTC hearing aids will encourage more people to take the first step sooner toward taking charge of their hearing health. HLAA does not endorse any product or service or any type of technology including hearing aids or wearable hearing devices sold over the counter or through hearing care professionals. HLAA does support quality, safe and effective technologies and hearing aids that give consumers affordable choices to make their own decisions.

First of all,let's make a brief introduction to the hearing aids device.A hearing aid is a device that is fitting behind the ear or fits in the ear which helps to make sound more audible for the wearers. Typically, hearing aids are designed to amplify and deliver quality sound to the ears. Hearing aids are used to help people who have hearing loss problems,including the children,adults,elderly and any of men or women.

Then,do you know what is the reason to cause people hearing problem?People with hearing problems are usually as a results of damage to the small sensory cells in the inner ear. This is called sensorineural hearing loss and due to disease, aging, or injury from loud noise and even medications.

There will be too much inconvenient for people who have hearing problem,it is hard to hearing the sound outside or a little far away from ears,and the hearing problem will affect the communication well with friends,colleagues,as well as families and so on.So,it is very necessary to improve the hearing problem to enhance the sound.And as the hearing aids manufacturer,the Great EarsMate suggest you to wear the right hearing aid device or hearing amplifiers to improve the hearing problem.

As hearing aids are designed to help the hearing impaired, of course its main purpose is to improve speech comprehension.  It helps improve the hearing capacity of a person who suffered hearing loss due to some disease or injury and aging. By using hearing aids, people are able to hear and communicate better with other people. This Earsmate Hearing AID aids to facilitate people to continue and participate in their everyday  activities with minimum difficulties. Most hearing aids can even help people hear better than normal people in certain environments. 

There are many different types of hearing aids,which depend on its case or shape.

It is including the types of:

1.Behind-the-ear (BTE) aids: Most parts are contained in a small plastic case that rests behind the ear; the case is connected to an earmold or an earpiece by a piece of clear tubing. Also, the BTE aids are easy to be cleaned and handled, and are relatively sturdy.

2."Mini" BTE (or "on-the-ear") aids: A new type of BTE aid called the mini BTE (or "on-the-ear") aid. It also fits behind/on the ear, but is smaller. A very thin, almost invisible tube is used to connect the aid to the ear canal. Mini BTEs may have a comfortable ear piece for insertion ("open fit"), but also increase comfort, reduce feedback and address cosmetic concerns for many users.

3.In-the-ear (ITE) aids: All parts of the hearing aid are contained in a shell that fills in the outer part of the ear.

4.In-the-canal (ITC) aids and completely-in-the-canal (CIC) aids: These hearing aids are contained in tiny cases that fit partly or completely into the ear canal. However, their small size may make them difficult to handle and adjust for some people.

According to the 4 different types of hearing aids,we Earsmate suggest to provide the BTE hearing aids types to elderly people.

Because,the BTE aids are easy to be cleaned and operated, and are relatively sturdy.Meanwhile,there are many advantages with the BTE hearing aids:

1.The BTE hearing aids is the most powerful hearing aid device. While it's appropriate for all types of hearing loss, it's the only option for people with severe hearing loss and may be the best option for people with high-frequency hearing loss.

2. The BTE hearing aid will produce minimal feedback (an audible whistle) even when the volume is turned up high because the components are farther apart than those in smaller hearing aids.

If you are wearing any hearing aids,you must to know the ways of how to clean them to keep good sound quality and extend the hearing aid life span.

And how you clean the hearing aids will depend on whether you wear a behind-the-ear (BTE), in-the-ear (ITE), or receiver-in-canal (RIC) model. Regardless of style, you can always use a soft, dry cloth to polish the external speaker units. When handling your hearing aids, hold them above a soft surface for protection, just in case you drop them. Do not clean with disinfectant wipes unless the packaging states that they have been approved for use with a hearing aid. Never use water or any kind of cleaning fluid to wipe your hearing aids—a gentle rub should be enough to remove dirt and moisture from the external shell.

It is best to clean your hearing aids before bed so that they can air out overnight. To keep debris from getting lodged further inside the hearing aids while cleaning any interior compartments, hold the hearing aid upside down. The seat for your hearing aid battery should also be wiped down every time the battery is replaced to maintain the length of charge stated on the battery packaging.

The best hearing aids for the hearing loss people which are not depended on neither the highest price,nor the famous brand.But,which one is the best for the users?

The decision you make will depend greatly on the degree of your hearing loss as well as your health and the lifestyle you lead,and your economic conditions.

Therefore,when you are looking for the best hearing aids to improve the hearing loss,there are a few things to consider.

1.Are you a technology buff?

Hearing aids have changed a lot in the last ten years. Today’s hearing devices are nothing like those your parents or grandparents may have worn, mainly because of advances in technology. Most of today’s devices can be controlled discreetly by the wearer with smartphone apps as listening environments change.If you're not a technology lover, don't despair - the technology in your new hearing aids can also work behind the scenes automatically so you can just focus on hearing your best.

2.Is your world noisy?

Let’s face it -- life can be loud! Depending upon what you do for a living and how often you’re socially engaged with people you love spending time with, directional microphone technology can help you make sense of that noise.Nearly all hearing aids today have some form of noise reduction built in. This technology is best for increasing your comfort in noisy situations.

3.Are you self-conscious about your hearing loss?

Let’s be clear: there’s absolutely nothing wrong with wearing hearing aids -- no matter whether they’re visible to others standing close to you or fit snugly out of sight inside your ear canal.

However,if you prefer to be more discreet about their hearing loss. Our tiny receiver-in-the-canal (RIC) or receiver-in-the-ear (RITE) Earsmate of Hearing AID G-28-RIC with ultra-thin tubing and an availability of colors which blend with skin or hair may be desirable. For even more invisibility, invisible-in-the-canal (IIC) or completely-in-the-canal (CIC) styles may be an option,such as the Earsmate Hearing AID of G-16 invisble hearing aids,which will be the good choose.

There are 10 benefits for wearing 2 sets of a pair hearing aids for both ears,said by Earsmate hearing aids supplier from China.

1. To improve the ability of sound source positioning by ears

2.To Improve the noise reduction and speech comprehension

3. To enhance the binaural loudness integration effect

4.To avoid delayed auditory deprivation effect

5.To delay the auditory nerve function decline

6.To  improve listening comfort, participate in multiplayer conversation

7. To eliminate the Cephalometric effect

8.To mask the tinnitus phenomenon

9. To prevent unilateral auditory fatigue

10. To reduce the Occlusion effect

As the practice proved, for the first time fitting or unilateral ear wear users, the Occlusion effect has reduced obviously after wearing 2 sets of pair hearing aid for both ears.

The occlusion effect occurs when an object fills the outer portion of a person's ear canal and that person perceives "hollow" or "booming" echo-like sounds of their own voice. It is caused by bone-conducted sound vibrations reverberating off the object filling the ear canal. When talking or chewing, these vibrations normally escape through an open ear canal; most people are unaware of their existence. When the ear canal is blocked, the vibrations are reflected back toward the eardrum. Compared to a completely open ear canal, the occlusion effect can boost low frequency (usually below 500 Hz) sound pressure in the ear canal by 20 dB or more. This effect can be measured with a probe-tube microphone.

A person with normal hearing can experience this by sticking their fingers into their ears and talking. Otherwise, this effect is often experienced by hearing aid users who only have a mild to moderate high-frequency hearing loss, but use hearing aids which block the entire ear canal.

Active occlusion algorithms are needed to help people with severe hearing loss adequately. If a person suffers from "near-normal low-frequency hearing and mild to moderate hearing loss of up to 70 dB at mid and high frequencies," hearing aids with increased vent size or hollow ear-molds/domes are more suitable for them in lessening the extent of the occlusion effect.

Hearing loss plagues millions of Americans, and it is one of the most frustrating health conditions with impacts that go well beyond communication difficulties. Maybe that's why we get so many questions about whether or not there is a way to quickly and easily restore hearing levels to normal, especially for common sensorineural hearing loss. The short answer to this question is "not really." Unfortunately, some people with hearing loss cling to the hope that some of these so-called remedies will provide immediate relief.

While any operation can cause anxiety, some people with hearing loss would be willing to go under the knife if they knew their hearing could be restored to normal.

The most common surgeries performed on the ears are:

Insertion of middle ear tubes - Hardly a surgery, this frequently-performed, outpatient procedure can be done right in your ENT's (otolaryngologist) office. Middle ear, or pressure equalization (PE) tubes, are used to alleviate pressure buildup behind the eardrum in cases of middle ear infection or fluid that cannot drain through the Eustacian tubes. Children are the most common candidates for PE tubes because their not-yet-developed ear anatomy makes ear infections more prevalent than in adults. Middle ear infections and fluid buildup usually cause some temporary conductive hearing loss that will improve post-surgery. However, for the majority of adults whose hearing losses are sensorineural, this surgery is not appropriate and would have no value.

Cochlear implants - A cochlear implant is a surgery for adults and, more commonly, children who have no, or very little, residual hearing. It works by bypassing a severely damaged cochlea to send electrical impulses to the hearing nerves that can be translated by the brain as meaningful sound. If you have significant hearing loss, you may wonder if you can just skip hearing aids and go right to an implant. Cochlear implantation is an invasive and costly surgery that is reserved for only the few. In fact, before someone can be considered a candidate if they are not completely deaf, they must have tried hearing aids without success.

Stapedectomy - Conductive hearing loss can result from the tiny bones of the middle ear becoming immobile and ineffective for transmitting sound to the inner ear. Otosclerosis is a common reason this can happen, and it results from extra bone material forming around the footplate of the stapes, the innermost bone of the middle ear. A stapedectomy is a procedure in which the stapes is replaced with a prosthesis. This surgery is reserved for specific medical conditions that create conductive hearing loss and is not used for sensorineural hearing loss.

Restoring the type of permanent hearing loss experienced by most adults due to natural aging, noise exposure, ototoxic medications and other causes isn't as straightforward as correcting some other medical conditions, but it's far from difficult. Restoring your hearing can be as simple as visiting a hearing care professional and being professionally fit with appropriate hearing aids.we share you the popular hearing aids brands,including the Siemens,Starkey,Widex,Sonic,Octicon,Uniton,Phonak,resound,rexton,Earsmate etc.

Research into ageing has shown links between dementia and hearing loss. According to researchers on Ageing, people with hearing loss lose more brain matter each year than those with normal hearing.

They studied MRI scans taken over the course of 10 years to see how the brain shrinks as it ages. These scans clearly showed that the participants with hearing loss were losing an extra cubic cm each year than hearing participants. It also showed that the greater the hearing loss, the greater the loss of brain tissue.

The areas most affected by tissue loss are the parts of the brain dedicated to auditory processing.

Some specialists have said that this is not surprising. If part of the brain is unused it will begin to waste away, just like any other part of the body. Other scans have shown that the brains auditory processors become utilized by the visual part of the brain. This makes sense as people with hearing loss rely more on visual cues for communication.

Researchers have also suggested that the part of the brain responsible for auditory processing is also used in retaining information and working memory. If this area is shrinking then that would account for the link between hearing loss and dementia.

Another suggestion for the link is cognitive overload. Everyday activities and communication become much harder when you can’t hear. This extra effort by the brain becomes exhausting over time and the brain has less energy for other processing tasks, such as memory.

Social factors also play a part in dementia. People who suffer from depression and become socially isolated are more at risk of developing dementia. So it’s possible that people who become socially isolated or depressed through their hearing loss become part of that high risk group.

So how can hearing aids help?

Hearing aids are primarily useful in improving the hearing and speech comprehension of people who have hearing loss that results from damage to the small sensory cells in the inner ear, called hair cells. This type of hearing loss is called sensorineural hearing loss. The damage can occur as a result of disease, aging, or injury from noise or certain medicines.

A hearing aid magnifies sound vibrations entering the ear. Surviving hair cells detect the larger vibrations and convert them into neural signals that are passed along to the brain. The greater the damage to a person’s hair cells, the more severe the hearing loss, and the greater the hearing aid amplification needed to make up the difference. However, there are practical limits to the amount of amplification a hearing aid can provide. In addition, if the inner ear is too damaged, even large vibrations will not be converted into neural signals. In this situation, a hearing aid would be ineffective.
