What is hearing Aids?
Hearing aids are small electronic devices, that are highly customized according to the need of the patient. These aids have one basic structure that includes a microphone to catch the sound, a computer chip that amplifies and processes the sound, a speaker that sends the signal to ear, and a battery for supplying power.
How it performs its function?
These aids amplify the sound that is going into the ear. There are different types of hearing loss. One of them is sensorineural hearing loss-meaning that some of the tiny hair cells of the inner ear are damaged. The other healthy hair cells catch the sound delivered by the hearing aid and send them as neural signals to the brain via the auditory nerve.
How will I need a hearing aid?

Your doctor will also perform the hearing test and find out the cause, type, and severity of your hearing loss.

What are the types of hearing aids?
Behind-the-ear (BTE) hearing aids consist of a plastic case that is worn behind the ear and attached to a plastic earmold that fits inside the outer ear. The electronic parts are present in the case behind the ear. Sound travels from the hearing aid through the earmold and into the ear. BTE aids are used by people of all age groups for mild to profound hearing loss.
In-the-ear (ITE) hearing aids fit completely inside the outer ear. They are used for mild to severe hearing loss. The outer case holding the electronic components is made of firm plastic. Some ITE aids may have advanced features installed in it, such as a telecoil.
A telecoil is a small magnetic coil that allows users to receive sound through the circuitry of the hearing aid, rather than through its microphone. This makes it easier to hear conversations over the telephone.ITE aids usually are not worn by young children because the casings need to be replaced often as the ear grows with the age of child.
Canal aids fit into the ear canal and are available in two styles.
- The in-the-canal (ITC) fits the size and shape of a person’s ear canal.
- A completely-in-canal (CIC) hearing aid is nearly hidden in the ear canal.
Because of small size, canal aids may be difficult for a person to adjust and remove. Moreover, canal aids have small size available for batteries and additional devices, such as a telecoil. They usually are not recommended for young children or for people who have severe to profound hearing loss because their reduced size limits their power and volume.
