Do you feel like someone is whispering to you when you talk to them? Or do you have to turn the TV up a lot louder than others? If this is common to you, you may have a hearing loss problem. But don't worry, there are good solutions for this. Today we are talking about one such major solution, Hearing Aids, which have made the lives of many people easier.
What is a hearing aid? How does it work?
Simply put, a hearing aid is a small electronic device that is placed in or behind your ear. Its main purpose is to amplify or increase the volume of sound waves in the surrounding environment to a level that you can hear clearly. This makes it much easier for a person with hearing loss to communicate with others and understand the sounds around them.
The way this device works is very simple. It has three main parts:
- Microphone: This is what takes in outside sounds.
- Amplifier: This part increases the sound picked up by the microphone to a level that you can hear.
- Speaker/Receiver: The amplified sound is sent into the ear through this small speaker.
Think of it like a small sound system. It takes in sound, amplifies it to the desired level, and delivers it to your ears.
Types of batteries used for this
Hearing aids are powered by batteries. Some require small batteries that are usually removable. But many new hearing aids now come with rechargeable batteries. That means, just like your smartphone, you can charge them at night and use them in the morning. It's very easy.
Who is best suited to a hearing aid?
Hearing aids are most effective for people with a condition called sensorineural hearing loss . This is a bit of a medical term, but it simply refers to hearing loss caused by damage to the inner ear or the auditory nerve that connects the ear to the brain. There are several possible causes of this condition.
- Aging
- Some diseases (e.g. diabetes)
- Ear infections
- Exposure to loud noise over a long period of time (e.g. working in factories)
- Side effects of some medications
If you have hearing loss due to this reason, a hearing aid may be a great solution.
Who performs the ear examination and hearing aid fitting?
There is a professional who has been specially trained for this. We call them audiologists . Usually, your family doctor (PCP) or an ear, nose, and throat specialist (ENT specialist) will refer you to this person.
An audiologist will first perform a hearing test . This will determine the level and type of hearing loss you have. Based on the results of the test, they will determine whether you need a hearing aid and, if so, what type of hearing aid is best for you. They will then fit the device to your ear so that it fits properly and comfortably.
Hearing aids that are prescribed and available over-the-counter
We can talk about two main types of hearing aids.
1. Prescription hearing aids: These are customized by an audiologist based on your hearing test report. These are the most effective for most people with mild, moderate, and severe hearing loss. Because they are custom-made , you will need to see your audiologist at least once a year for recalibration.
2. Over-the-Counter (OTC) hearing aids: These are considered to be suitable for people with mild to moderate hearing loss. They only amplify sound, but cannot be adjusted specifically for you.
This is like eyeglasses. Some people buy 'readers' glasses from a regular store to read books. But someone with a specific vision impairment needs glasses prescribed by an eye doctor. The same goes for hearing aids.
Therefore, to know exactly which type is right for you, it is best and safest to consult a doctor or audiologist.
| Hearing aid type | Features and differences |
|---|---|
| Prescription | Custom-made by a specialist to suit your hearing loss. More effective. Requires periodic adjustments. |
| Over-the-counter (OTC) | Works as a general sound amplifier. No specific adjustments can be made. May be suitable for minor hearing impairments only. |
Advantages and disadvantages of using a hearing aid
Main advantages
- Being able to hear sounds well in different environments (e.g., in a crowd, in a quiet place).
- Ease of conversation and communication with others.
- Increased ability to understand what others are saying.
- Gaining more independence.
- For some people, the constant ringing in the ears (tinnitus) may also decrease.
Some inconveniences or disadvantages
A hearing aid is an aid to hearing loss, not a cure . This means that your hearing cannot be restored to 100% normal, but it can help you make the most of your current ability.
- It may take a few months to get used to this.
- At first, your own voice may sound louder to you (but your body will get used to it after a few weeks of use).
- Sometimes these can be a little expensive.
- If hearing difficulties arise in certain environments (e.g., very noisy places), adjustments may need to be made again by the audiologist.
How long can it be used? And when should I see a doctor?
If properly maintained, a single hearing aid can last for about 6-7 years. Another advantage of new devices is that if your hearing level changes over time, you can simply re-program the existing one without having to buy a new one.
If you have the following symptoms, this is a good time to talk to your doctor about hearing aids.
| When to seek medical advice | |
|---|---|
| If you always feel like everyone around you is speaking softly or in a whisper. | |
| When speaking, you have to ask "What did you say?" several times. | |
| If you have difficulty hearing people on the phone. | |
| If you have a hard time understanding someone when speaking to a group. | |
| The volume of the TV or radio, if you need it more than others in the house. | |
The difference between hearing aids and other hearing devices
In addition to hearing aids, there are other types of hearing aids. They are different from each other.
| Equipment type | Functionality and compatibility |
|---|---|
| Hearing Aid | Amplifies external sound and delivers it to the ear. Recommended for mild, moderate, and severe sensorineural hearing loss. |
| Cochlear Implant | A device that is surgically implanted inside the ear. It directly stimulates the auditory nerve. It is recommended for people with severe hearing loss who are not responding to regular hearing aids. |
| Bone-Anchored Implant | This is also a surgically implanted device. It transmits sound as vibrations through the bones of the skull to the inner ear, which functions best. It is suitable for those with conductive hearing loss or those who are deaf in only one ear. |
Only your doctor or audiologist can give you the best advice on which device is right for you.
Take-Home Message
- Hearing loss can affect your quality of life, so don't ignore it.
- Hearing aids are devices that amplify sound and help you hear, but they do not completely cure hearing loss.
- To choose the hearing aid that best suits you, be sure to see a doctor or audiologist for an examination.
- You can extend the life of your hearing aid by cleaning it properly and maintaining it well.
- Don't be afraid to seek help. With the right solution, you can hear the world clearly again.
