A hearing aid is a small electronic device that you wear in or behind your ear. It makes some sounds louder so that a person with hearing loss can listen, communicate, and participate more fully in daily activities. A hearing aid can help people hear more in both quiet and noisy situations. However, only about one out of five people who would benefit from a hearing aid actually uses one.
A hearing aid has three basic parts: a microphone, amplifier, and speaker. The hearing aid receives sound through a microphone, which converts the sound waves to electrical signals and sends them to an amplifier. The amplifier increases the power of the signals and then sends them to the ear through a speaker.
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.
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.
How can I find out if I need a hearing aid?
If you think you might have hearing loss and could benefit from a hearing aid, visit your physician, who may refer you to an otolaryngologist or audiologist. An otolaryngologist is a physician who specializes in ear, nose, and throat disorders and will investigate the cause of the hearing loss. An audiologist is a hearing health professional who identifies and measures hearing loss and will perform a hearing test to assess the type and degree of loss.
What are the different styles of hearing aids?
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. This style is often chosen for young children because it can accommodate various earmold types, which need to be replaced as the child grows. Also, the BTE aids are easy to be cleaned and handled, and are relatively sturdy.
“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 may also use a traditional earmold. Mini BTEs allow not only reduced occlusion or “plugged up” sensations in the ear canal, but also increase comfort, reduce feedback and address cosmetic concerns for many users.
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. The ITE aids are larger than the in-the-canal and completely-in-the-canal aids (see below), and for some people may be easier to handle than smaller aids.
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. They are the smallest hearing aids available and offer cosmetic and some listening advantages. However, their small size may make them difficult to handle and adjust for some people.
How can I care for my hearing aid?
Proper maintenance and care will extend the life of your hearing aid. Make it a habit to:
- Keep hearing aids away from heat and moisture.
- Clean hearing aids as instructed. Earwax and ear drainage can damage a hearing aid.
- Avoid using hairspray or other hair care products while wearing hearing aids.
- Turn off hearing aids when they are not in use.
- Replace dead batteries immediately.
- Keep replacement batteries and small aids away from children and pets.
Do you constantly face problems in hearing and find difficulty in understanding what others are saying? The hearing aid fitting hospital in Jaipur can be a boon for you as you can get your hearing problem cured with high-quality treatment services that specifically aims at overcoming the auditory problems of the individuals. A hearing aid can be recognized as a unique electronic device that is generally worn behind the ear. A person suffering from hearing difficulty can positively benefit from the device as it supports better listening and communication by making sounds louder. Subsequently, routine activities are performed in a better manner.Treat hearing difficulties with the best hearing aid fitting hospital in Jaipur
The hearing aid is considered to be of utmost importance to the people suffering from a hearing disorder and it enables the patients to hear clear voices in both noisy and quiet situations. But the fact is that only a few i.e. one out of five persons actually make the use of hearing aid for long term benefits. The hearing aid is made up of three important components:
- Microphone: This part of the hearing aid enables the user to receive sound through a microphone that subsequently converts the sound waves to the electrical signals and transfer these to the amplifier.
- Amplifier: The role of amplifier is to enhance the power of signals.
- Speaker: The ear is able to receive the voice through the speaker.
According to the hearing aid fitting hospital in Jaipur, the hearing aids serve a useful purpose in order to improve the speech and hearing comprehension of the individuals who are experiencing hearing loss. This hearing loss might occur due to significant damage to the hair cells which are typically the small sensory cells located in the inner ear. This kind of hearing loss is referred to as sensorineural hearing loss. Moreover, there are also other factors responsible for damage such as specific types of medicines, any disease, age factors along with injury caused due to excessive noise.
Moreover, the working of the hearing aid needs to be understood so that a person suffering from hearing difficulty is able to decide whether the hearing aid will be beneficial for him/ her not. The core purpose of the hearing aid is to magnify the sound vibrations that tend to enter the ear. The vibrations can be converted into the neural signals with the help of surviving hair cells that help in the identification of larger vibrations. Thus, they are passed to the brain. Further, the amount of amplification mainly depends upon the damage that has been caused to the hair cells. Thus, if the damage is of high-level, the patient needs a hearing aid amplification of greater intensity. Therefore, there can be circumstances when the hearing aid might not benefit the patient if the inner ear is highly damaged since the larger vibrations will not be able to convert into neural signals.
In addition to this, the hearing aid fitting hospital in Jaipur suggests that there are different types of hearing aids available such as Behind-the-Ear hearing aid (BTE), In-the-Ear hearing aid (ITE) and the canal hearing but it completely depends on the condition and severity of hearing loss and damage that which hearing aid will be suitable for the patient. The best way to find out whether the patient is experiencing hearing difficulty or not is to consult an audiologist or otolaryngologist. The audiologist can identify the real causes responsible for the hearing damage and can recommend for certain of hearing tests that can help in evaluating the degree of hearing loss.
