You’ve known you’ve had a hearing loss for quite some time now and you finally get up the nerve to get your hearing tested. They tell you that you need a hearing aid and you cant help but think, Why did this have to happen to me?? Then they start telling you about hearing aids and use tons of terminology that just goes right over your head. Dont they know that you are in shock?? How can you make an informed decision about anything when you dont even know what they are talking about!?

There are hundreds of different hearing aids. It can be a very complicated world of technilogical terms. Sometimes those of us that work with hearing aids all the time can forget just how foreign they can sound to you. To make matters worse, the manufacturers like to call things different names, so they sound like something different. No wonder there’s so much confusion!

I am going to try to unravel some of the mystery for you. When you get down to it, there are really only a few terms you need to understand. These features are the ones that really matter, and the model or the style of the hearing aid.

There are seven primary styles of hearing aids: ITE, Half Shell, ITC, Mini Canal, CIC, BTE, and Open Ear.

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. 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.
