Are Two Hearing Aid Machines Better Than One?

Have you ever wondered why we have two ears? The efficiency of two organs performing is higher than a single performing organ. So should we use one Hearing aid machine or two? Read to find out The post Are Two Hearing Aid Machines Better Than One? appeared first on...

Have you ever wondered why we have two ears, two eyes, two legs and so on? Not really, we take all these for granted. There is very sound logic in having two organs or limbs. These organs perform in pairs. The efficiency of two organs performing is higher than a single performing organ. It brings us to the basic question. Should we use one Hearing aid machine or two? Are two hearing aid machines better than one? Are you buying hearing aid machines for the first time? If so, it is advisable that you should know what to expect at your first Hearing aid machine fitting session.

Are Two Hearing Aids better than One

Do I Need Two Hearing Aid Machines?

Your Audiologist is the best judge to decide. Your Audiogram report indicates the Hearing loss in each ear. If both your ears have a Hearing loss, then it is advisable to use two hearing aid machines. Two hearing aids are also known as Binaural Hearing Aids. Majority of the people suffer from Sensorineural Hearing loss. Hearing Impairment due to Sensorineural hearing loss is generally in both ears. Hearing loss in both ears is also known as Bilateral Hearing Loss.

Why Two Hearing Aid Machines Are Better Than One?

Let us find out why two hearing aid machines are better than one. As mentioned earlier, some of our organs work in pairs. Our ear is one such organ. To understand better read How does my Ear Work. Mentioned below are some of the advantages of using two Hearing aid machines. Or binaural hearing aid fitting.

For some people. Hearing aid price could be a reason for not using two Hearing aid machines. Every brand offers a wide range of hearing aid machines at affordable prices. These hearing aids too have suitable features which are helpful for a normal lifestyle. Select a Hearing aid machine which suits your lifestyle and needs.

Problems in Using One Hearing Aid Machine

1. Localisation or Source of Sound

Diagram Localisation of Sound
Localisation of Sound

Localisation or source of sound gives us a sense of direction. We know the direction from where the sound is coming. As a simple reflex, we turn towards the source. Or towards the person talking or a car honking. The sound picked up by both the ears is simultaneously send to our brain for processing. The brain processes the signals received from the left and the right ear. After processing both the signals it informs us of the direction of the sound. Or from which direction the sound originated. We automatically turn towards the direction of the sound.

Comparison Between one and two hearing aids
Comparison Between one and two hearing aids

How Does The Brain Judge The Direction of Sound?

The brain calculates the time difference to judge the direction of the sound. If the sound signal reaches both the ears at the same time, the source of sound is in the centre. If the sound signal reaches the left ear first, then the source of sound is towards the left.

So, is it right to use only one hearing aid machine? The answer is a big no. Nature has given us a binaural hearing system. A person using only one hearing aid machine will not know the direction of the sound.

The following problems may occur if the localisation or source of sound is not clear.

i. It can be dangerous when the car honks and we look in the wrong direction. Two hearing aid machines are necessary for safety.

ii. Someone calls out to us and we look in the wrong direction.

iii. We are not sure who is speaking during office meetings and group discussion.

Binaural Hearing Communication

Our Brain coordinates the signals from the left and the right ear. Manufacturers also provide this facility in Hearing aid machines. This is a feature called Binaural hearing Communication. Read in detail about this feature. And other features available in advanced Digital Hearing Aid machines.

2. Reducing Background Noise

Background noise reduction is also a reason why two hearing aid machines are better than one. The biggest challenge for the manufacturers is reducing the background noise. The hearing aid machine amplifies the noise along with the speech signal. Advanced digital hearing aid machines have excellent noise reduction features. Background noise reduction works much better if the person is using two hearing aids.

when we use two hearing aid machines, each hearing aid is set at a lower volume setting. Lower volume setting results in lower noise levels.

3. Less Distortion

In the case of two hearing aid machines, the volume setting of each hearing can be set low. This results in better speech quality and higher clarity of sound. In the case of one hearing aid machine use, a higher volume has to be set.

4. Smaller or Invisible Hearing Aid Machines

Invisible in the Canal Hearing Aid in the Ear
Invisible in the Canal Hearing Aid in the Ear

Everyone wants a small Hearing aid machine which is not visible to others. High powered hearing aid machines are big in size. Parts like the receiver and the complete circuit are big so they deliver high output. The battery size also increases to meet the demand of high amplification. This increases the overall size of the Hearing aid machine. Hearing aid machines delivering lower output are generally smaller in size. One can select a smaller size hearing aid machine in case of binaural hearing aid fitting. .A single hearing aid machine user will need a bigger size machine.

5. Head Shadow Effect

If we are using a hearing aid machine in the left ear and someone calls from the right. Our head interferes with the sound. The sound has to travel around the head to reach the ear with the hearing aid machine. There is a loss of clarity. This is the head shadow effect.

6. Auditory Deprivation

Exercising regularly keeps us fit and healthy. Similarly, our hearing system also needs exercise to stay fit. If we use only one Hearing aid machine, the other ear does not get the required stimulation. The hearing loss increases much rapidly in the ear without a Hearing aid machine. This is Auditory Deprivation.

7. Increase in Stress

Straining to catch a conversation results in increased stress. Increased stress causes tiredness and fatigue. Increased stress leads to other medical issues in people with hypertension and diabetes.

When is it OK to Use One Hearing Aid Machine?

There are certain conditions where one hearing aid use is acceptable.

  • Some people may have a Mild or Moderate Hearing loss in one ear. The other ear can be normal. In this case, a person can use one hearing aid.
  • In cases where one has lost total hearing in one ear. One ear can have 100% loss due to an accident. In this case, a hearing aid machine in the ear with total loss cannot help. In this case, a Hearing aid machine in the other ear is advisable.

Use of a Hearing aid machine is advisable even in case of Mild hearing loss. Use of two hearing aid machines makes the sound very close to natural hearing.

How do Hearing Impaired Students take Exams like IELTS & PTE?

IELTS, PTE, TOEFL, etc. are the tests that students need to take to prove their English language proficiency. these tests require the candidate to read, write, speak and listen, We will tell you how students with hearing impairment take it. The post How do Hearing Impaired Students take Exams like IELTS & PTE? appeared first on...

TOEFL PTE exams for the Hearing impaired

IELTS, PTE, TOEFL, etc. are the tests that students need to take to prove their English language proficiency. Students from non-English speaking nations who seek international education consultants  in English-speaking nations, must take any of these tests. Every country recognizes different test and the student must take particular test in order to study in that country. These tests check the candidate on 4 aspects of English language – reading, writing, speaking and listening.

As these tests require the candidate to read, write, speak and listen, one wonders how students with hearing impairment take it! While there are provisions in most of the course curriculums for students with hearing and speech impairments, the conducting authorities of such tests have also made special arrangements for students with special abilities.

The test authorities aim to ensure that every candidate is treated fairly and objectively and that they are given optimum conditions to take their exams, for which they can make arrangements to accommodate special circumstances or requirements to enable test takers to attend a test centre, to understand questions and to give their exam answers.

Special Arrangements for Students with Special Abilities

When it comes to IELTS or any such test, it may take up to 3 months for some special arrangements to be made for students with hearing impairment; this is the reason the candidates are advised to make application as soon as possible through the test centre. In this case, the test centre will do the following for the candidate:

  • Confirm the application deadline (this depends on the arrangements candidate needs and is typically from two weeks up to three months before the test)
  • Ask for full details of difficulty
  • Make the arrangements needed to take the test
  • If the centre does not have the equipment or space needed by the candidate (e.g. a separate room), they will do their best to help find another centre that does
  • The centre may also ask to provide a medical certificate

Authorities can also make arrangements for headphones or special amplification equipment upon request.

Lip-Reading Version of Listening Test

There is a version of the Listening test for students with hearing impairment in which the student needs to read the lips of the supervisor (lip reading). In this, instead of playing a recording, the supervisor (the person who gives Listening test) reads out the material. Each text is read out twice. The supervisor will stop reading from time to time during the second reading, which gives the candidate time to write the answers. However, the candidate must be prepared to take this lip-reading version of Listening test and must make sure that he/she can lip-read a person who is speaking English. They can practise with sample papers before the test.

Exemptions and Endorsed Certificates

There have been documented evidences where the students have been exempted from Listening test in case of severe hearing loss/disability and if the candidate cannot lip-read. This means that the candidate does not need to take the test. However, the candidate must apply for exemption before taking the test. Exemption can be taken from one or two components depending upon the disability (hearing and/or speaking). The candidate is given a score for the missing component(s) based on their performance on the other components of the test. This score is used to calculate Overall IELTS Band Score, and the Test Report Form has the following statement printed on it: ‘Due to extreme speaking/hearing (etc.) difficulties, this candidate was exempt from the Speaking/Listening (etc.) test(s). The Speaking/Listening (etc.) test Band Score(s) has/have been notionalised on the basis of the average of the other two/three Band Scores.’

Timeline & Extra Cost

As the test authorities aim to ensure every candidate is treated fairly, they do not charge anything extra for the Special Arrangements service. They only require the candidate to contact the authorities before the registration deadline so that necessary arrangements can be made.

It is to be noted that no application will be considered unless there is a supporting medical certificate. Therefore, candidates need to make sure they furnish the medical certificate for their disability beforehand.

Hearing Loss Treatment

Hearing Loss is a very common ailment. Yet, people delay visiting the Audiologist or the Doctor. Delay in Hearing Loss treatment can cause long-term damage. The post Hearing Loss Treatment appeared first on Earguru.

Hearing Loss is a very common ailment. Yet, people delay visiting the Audiologist or the ENT Doctor. Delay in Hearing Loss treatment can cause long-term damage. In Children, untreated Hearing loss affects the education. In youth, untreated Hearing loss results in loss of self-esteem and job opportunities. Among the working professionals, untreated Hearing Loss can harm their career. Inability to take part in family discussions leads to depression in Senior citizens. Use these tips to convince elders to use Hearing aids in case they are reluctant.

Hearing Loss Treatment

Types of Hearing Loss

Before we discuss the Hearing Loss treatment. We should be familiar with the types of Hearing Loss. There are 3 types of Hearing Loss.

1. Sensorineural Hearing Loss

This type of Loss relates to the Sensory- Neural parts of the hearing system. Sensory parts are organs which sense sound waves. Neural parts are the nerves which carry the sound signal to our Brain. Any damage to these parts results in Sensorineural Hearing Loss.

Outer, Middle & Inner Ear Structure
Outer, Middle & Inner Ear Structure

2. Conductive Hearing Loss

This type of loss relates to the parts of the ear which conduct sound. The Outer Ear and the Middle Ear form part of the conductive system. Any physical damage or deformity in this area causes Conductive Hearing Loss.

3. Mixed Hearing Loss

Defects in the Sensorineural and Conductive Hearing system causes Mixed Hearing Loss. Both types of Hearing loss contribute to the total Hearing loss.

4. Sudden Hearing Loss

Some people also get Sudden Hearing Loss. Some of the reasons for Sudden Hearing loss are exposure to a loud sound. More like a sudden explosion or a loud blast. Ototoxicity, or Ear Infections. People affected by Sudden Hearing Loss should rush to the Hospital. Timely medical help can save the Hearing.

How to Detect Hearing Loss?

In a majority of the cases Hearing Loss is due to advancing age or due to constant exposure to loud sounds. This type of Hearing Loss is not sudden and affects us very gradually.

Hearing Loss increases very gradually. Initially, the affected person is in denial and refuses to accept. The tendency of people suffering from Hearing loss is to blame others or blame the situation. “Why are you mumbling?” and “why can’t you speak clearly and loudly?” are some of the common complaints we hear from elders.

There are many signs which show that the person is suffering from Hearing Loss. Some of the signs are as follows:

Tips To Detect Hearing Loss

  1. The first sign is missing out on some words in a group conversation at home or in the office.
  2. Missing out on words if the surroundings are noisy. It is common in places like noisy restaurants or public places.
  3. Requesting others to repeat themselves.
  4. Keeping the Television volume very loud.
  5. You feel others are mumbling or not speaking clearly
  6. Unable to hear properly on the phone.
  7. Need to look at the person to hear well. A little bit of lip reading helps in understanding.
  8. The person feels exhausted after a lengthy conversation. This happens because the person tires due to more strain.
  9. The affected person avoids social functions. Due to the inability to converse in the group.

Hearing Loss can be due to Earache, ear discharge, blocked ears or sudden ear pressure. These symptoms are signs of temporary Hearing loss.

Confirmation of Hearing Loss.

Checking Ears with the Otoscope
Checking Ears with the Otoscope

Please note that the above tips show that the person might be suffering from Hearing loss. You should fix an appointment with the Audiologist or the Hearing Care Professional. The Audiologist will start with checking the ears with the Otoscope. The physical check will ensure that there is no earwax in the ears.

The next step is the Audiological tests. The Audiologist might conduct any of the following Hearing Tests.

  • OAE or Oto Acoustic Emission Test

This is a quick test which checks hearing up to the Inner Ear Hair Cells.

  • Pure Tone Audiometry Test

This test measures the level or severity of Hearing loss.

  • Impedance Testing

This test checks the functioning of the Middle Ear

  • ABR or Auditory Brainstem Response

This test is for babies. The test measures the Brains response to the tones and clicks presented to the ears.

Hearing Loss Treatment

The ENT (Ear, Nose and Throat) doctor and the Audiologist will study the reports. The reports will determine the intensity or severity and the type of Hearing Loss. The line of treatment will depend on the type of hearing loss.

Treatment for Sensorineural Hearing Loss

Age or accidents can cause weakness in the nerves or damage to the delicate Hair Cells in the Cochlea. This is a major cause of Sensorineural Hearing Loss. This type of Hearing loss is mostly permanent. Doctors do prescribe vitamin supplements, corticosteroids and drug therapy. To date, there is no direct cure for Sensorineural Hearing Loss. Research on Hair Cell Regeneration and Stem Cell Therapy is at an advanced stage. We will have a cure very shortly.

Currently, the recommended remedy for Sensorineural Hearing loss is use of Digital Hearing Devices.

 Treatment for Conductive Hearing Loss

In a majority of the cases Conductive Hearing Loss is curable. Unless the damage to the Outer Ear or the Middle is severe.

Causes of Conductive Hearing Loss

The following reasons can cause Conductive Hearing loss.

  • Earwax Accumulation

Cleaning the Ears can rectify the situation. Find out how to clean earwax at home.

  • Foreign Body Obstruction

This happens in the case of children. At times they insert beads or small play items in the ear. Removing them can restore hearing.

  • Ear Infection

Bacterial or Fungal infection can take place. Keep your ears clean to prevent infection. Consult the doctor who will prescribe antibiotics to clear the infection.

  • Abnormal growth in the Ear

Sometimes there is abnormal bone growth. This growth reduces the size of the ear canal. The problem can be surgically corrected.

  • Eardrum Perforation

Eardrum can rupture due to a build-up of pressure in the middle ear or due to an external injury.

In most of the above cases, Hearing Loss is reversible with proper treatment.

Treatment for Mixed Hearing Loss

A Mixed hearing loss is a combination of Sensorineural and Conductive Hearing Loss. Normally the Doctor will first start with the treatment of Conductive Hearing Loss. This will bring some relief to the patient.

Currently available treatment of Sensorineural Hearing loss cannot reverse hearing loss. Field trials are at an advanced stage and a cure will be available very soon.

What To Expect At Your First Hearing Aid Fitting

Do the reports show that you need Hearing Aids? If this is your first Hearing aid, you should know a little about the process of Hearing Aid fitting. The post What To Expect At Your First Hearing Aid Fitting appeared first on Earguru.

The Audiologist has conducted the necessary Hearing Loss tests on you. To your surprise, the reports show that you need Hearing Aids. The truth is that most of us will need Hearing aids at some stage in life. It may come as a shock to some but accept the fact. Discuss your requirements with the Audiologist or your Hearing care professional. If this is your first Hearing aid, you should know a little about the process of Hearing Aid fitting. There are different types of Hearing aids with different specifications. It is very important that you discuss your daily lifestyle with the Audiologist. Based on your lifestyle he or she will suggest the Best Hearing Aid for you.

What to Expect at your first hearing aid fitting

What is Hearing Aid Fitting?

The Hearing aid fitting begins with the evaluation of the Audiogram report. To walking out with your new Hearing Aids. Below is the brief description of the Hearing aid fitting process.

  • Selection of Hearing Aids

Your Audiologist is well qualified to decide the right hearing aid machine. Different Hearing Aid styles and models have different technical specifications or fitting range. The manufacturers provide the specifications to the Audiologist. It is advisable to convey the preferred cost or Hearing aid price range. This will make the selection process simple.

  • Can I Choose the Hearing Aid I like?

Styles and Types of Hearing Aids
Styles and Types of Hearing Aids

When it comes to the style or type of Hearing aid, you, the user have to play a pro-active role in the selection process. You have to discuss your needs and requirements. If you are a working professional, you will prefer a Hearing aid which is not visible. If your work involves talking to clients on the phone. You will certainly prefer a Hearing aid with Bluetooth connectivity. Read this article on Useful features in Digital Hearing aids.

  • Ear Impression for Mould or Shell Making.

Ear Mold Impression Process
Ear Mold Impression Process

Once you select the model and the style of the Hearing aid, the Audiologist will take the Ear Impression. The Audiologist will inject a special paste into the ear. The paste fills up the ear and solidifies in a few minutes. This solid impression is the precise shape of your ear canal and the outer ear.

The Audiologist sends the impression to the Ear mould or shell making laboratory. An Ear Mould helps in the physical fitting and reduces chances of Feedback. The impression is also required to make a shell for an ITC, CIC or an IIC Hearing Aid.

Programming or Tuning The Hearing Aids

Your Audiologist will call you again for the fitting and programming of the Hearing Aids. The laboratories take a few days to manufacture and deliver the Ear Moulds. Or the complete Hearing Aid if you have selected an In the Ear type.

Programming is a procedure to match the output of the Hearing aid to your Hearing Loss. No two people have the same pattern of Hearing Loss. So each Hearing aid’s performance and output is set or tuned to suit the user.

Expectations from Your First Hearing Aid Fitting

You are eagerly awaiting to hear with your new Hearing aids. The expectations are high, chances are that your first experience may be disappointing.

Initially, you will hear a lot of sounds making you uncomfortable. There is nothing wrong with the Hearing Aids. These are sounds which your Ear has not heard due to your Hearing Loss.

Do keep in mind that there will be a difference between natural hearing and hearing with a Hearing aid. Expecting to hear as well as before will disappoint you, get used to the new sound. You should have reasonable expectations from your Hearing Aids.

Understanding Hearing Aid Features

Digital Hearing aid technology has advanced rapidly. Manufacturers offer great features for the comfort and convenience of the user. Features like multi-program are also available in economical Hearing aids. Your Audiologist will explain all the features present in your Hearing aids. Make note of all the features as they will improve the hearing experience.

Adjusting To Your New Hearing Aids

Another shock awaits you as you step out of the clinic. The noise of cars passing by or some noisy activity on the street will sound unbearable. Do not panic, switch off your Hearing Aids and reach home. Our brain needs some time to process the new sounds. It’s a matter of time before the brain starts recognising the new sounds. Start using the Hearing Aids at home. Talk to your family members as you are familiar with their voice. Ask them to repeat if you miss a few words, do not ask them to talk loudly. Preferably use your Hearing Aids as long as you are comfortable, in case you feel tired, remove them. Increase the number of hours gradually over days.

Hearing Aid Adjustment Period

Discussion with the Audiolgist
Discussion with the Audiolgist

It generally takes 2 to 3 weeks to adjust to the new Hearing Aids. Do not get impatient and rush back to the Audiologist. You will be comfortable in a few weeks. If still not happy, make note of all the sounds that make you uncomfortable. Issues like unable to hear the door-bell. Unable to understand the speech of your wife or your children. Unable to talk on the phone etc.

Take an appointment and visit your Audiologist. Explain the issues bothering you, a little adjustment can solve them. Your Audiologist can tune the Hearing aids perfectly if you give proper feedback.

  • Hearing aid Maintenance Tips

Read the user manual provided by the Company. Understand the warranty terms and keep the warranty card safely. Your Audiologist will also offer handy tips to maintain your Hearing aids. Understand when and how to replace the battery and how to store the Hearing aids at night. Read about the simple at home maintenance tips.  to ensure that your Hearing aids give you years of trouble-free service.

Using Hearing aids will bring the fun back into your lives. Do things you always wanted to do. Go for movies, operas, listen to music.

Rechargeable Hearing Aids – The Pros and Cons

Inserting and removing Batteries is cumbersome. What if we could insert the Hearing aid Battery once and forget about it? Yes, it’s very much possible. Rechargeable Hearing aids and rechargeable hearing devices are now freely available. The post Rechargeable Hearing Aids – The Pros and Cons appeared first on...

Hearing aid batteries are the most important accessory of a Hearing aid. A dead or a weak battery means no working Hearing aid. 90% of the Hearing aid users buy disposable Hearing aid batteries. These batteries are inconvenient as they have to be replaced regularly. What if we could insert the Hearing aid battery once and forget about it? Yes, it’s very much possible. Rechargeable Hearing aids and rechargeable hearing devices are now freely available.

Rechargeable Hearing Aids Pros and Cons

Why Should We Buy Rechargeable Hearing Aids?

The priority of the Hearing aid manufacturers is to offer better sound quality and convenient features. Most Hearing aid users had initial resistance towards the use of Hearing aids. Please read this article if you or any of your acquaintance is reluctant to use Hearing aids.

Changing batteries is one of the most cumbersome routines. The user has no option but to replace the battery every few days or a few weeks depending on the use and the type of Hearing aid.

Let us look at some of the disadvantages of disposable Hearing aid batteries.

Disadvantages of Disposable Hearing Aid Batteries

  • The currently available Hearing aids do not come with an On-Off switch. The user has to open the battery compartment to shut the Hearing aid. Many elderly people forget to do so. If the compartment is not fully opened, the Hearing aid keeps working even if not in use. This results in increased battery usage.
  • It is difficult for elders with unsteady hands to insert the battery in the Hearing aid compartment. They have to depend on others to insert/remove the battery.
Difficulty in inserting battery in the Hearing Aid
Difficulty in inserting battery in the Hearing Aid
  • The battery tends to fall out of the compartment. It invariably rolls to the most inconvenient places and is never found. The user has to insert a new battery which increases expenses.
  • The new Digital Hearing aids have features like Bluetooth and audio streaming. The battery consumption increases if these features are regularly used. The user has to replace the battery more often.
  • The users have to stock up on batteries as they may suddenly run out of power leaving the Hearing Aid user helpless.
  • Disposable batteries have a tab which ensures that the battery stays fresh till ready to use. The battery starts working on removal of the tab even if not inserted in the Hearing aid.
  • The Hearing aid user has to make repeated trips to the shop to buy batteries. This is a major inconvenience for the elderly who stay alone.
  • Since these are disposable batteries, they are not environment-friendly as they are not recyclable.
  • Repeated cost is another factor. A small size 312 battery works for less than a week. One needs to buy a minimum of 52 batteries every year.
  • One has to be particular about the positive and negative side of the battery before inserting. A wrong insertion can break the battery compartment resulting in repairs and inconvenience.

Recent advances in rechargeable battery technology have made rechargeable hearing aids an attractive option.

What are the Types of Rechargeable Hearing Aids?

There are 2 popular types of rechargeable Hearing aid technologies.

  1. Lithium-Ion rechargeable battery technology
  2. Silver-Zinc rechargeable battery technology

Silver-Zinc is the latest technology and has a few advantages over Lithium-Ion technology.

Advantages or Pros of Silver-Zinc rechargeable Hearing aids.

  • Silver-Zinc battery is less polluting, hence it is eco-friendly.
  • Silver-Zinc battery is non-inflammable.
  • Silver-Zinc batteries are smaller in size. Suitable for use in smaller hearing aids.
  • Silver-Zinc batteries are removable. One can use a disposable battery in emergencies.
  • Silver-Zinc batteries can be retrofitted or suitable for use in older Hearing aids.

Disadvantages or Cons of Silver-Zinc Rechargeable Hearing Aids

  • Silver-Zinc rechargeable Hearing aid batteries last around one year.
  • They have lesser power than Lithium-Ion batteries.

Advantages or Pros of Lithium-Ion Rechargeable Hearing Aids

  • The batteries will comfortably last for 24 hours with a single charge.
  • The user can comfortably use Bluetooth and audio streaming with a minor reduction of battery life.
  • You will not have to replace the battery for 4 to 5 years

Disadvantages or Cons of Lithium-Ion Rechargeable Batteries

  • The Company seals the battery compartment. For any battery change, the hearing aid has to be sent back to the manufacturer.
  • The batteries are larger in size. May not be possible to use with small In the Ear hearing aids like a IIC or a CIC.
  • Lithium-Ion is poisonous in nature. Disposal of used batteries is not eco-friendly.

Advantages or Pros of Rechargeable Hearing Aids

All the leading global manufacturers of Hearing Aids manufacture Rechargeable Hearing Aids. Both the rechargeable technologies are being used depending on the required features.

Besides the standard charging dock for use at home, Starkey has marketed the VFusion rechargeable system. It is in the form of a USB pen drive with a battery charging circuit. Users can recharge their batteries on their laptops.
