A hearing aid is a battery-powered gadget created to improve your hearing. It works by amplifying sound through a three-part system; the microphone, amplifier and receiver. The microphone picks sound. The amplifier increases the strength of the signal, making it louder, and the receiver sends the amplified sound to the ear. Most hearing aids are for people who damage their inner ear or the nerve that links the ear with the brain. 

All hearing aids have the same essential parts, whether it is the traditional hearing aid or digital. They function by picking sound, making it louder and sending it to the ear. However, most hearing aids nowadays are digital and are powered by the traditional battery or rechargeable batteries. 

A small microphone collects sound, and a computer chip with an amplifier converts the sound into a digital signal. It analyses and adjusts the sound depending on your hearing loss, sound levels and listening needs. The amplified waves are then transformed back to sound waves and sent to your ear through receivers.

There are different types of hearing aids. 

1. Completely in the canal

The complete canal hearing aid is designed to fit in your ear canal. It helps people with mild or moderate hearing problems. They are the smallest group of hearing aid and are less likely to pick background noise. However, they often don't include additional features. 

2. In the canal 

In the canal, hearing aids are designed to fit in the ear canal partly. The hearing aid also help improve hearing for adults with moderate hearing loss. 

3. In the ear 

The ear hearing aid has two styles; one that fills most of the bowl-shaped area of your outer ear (full shell) and one that fills only the lower part (half shell). They are both helpful for people with severe hearing loss. Have larger batteries and may be easier to handle. 

4. Behind the ear

This type of hearing aid hooks over the top of your ear and rests behind it. A tube is designed to fit in your ear canal. The hearing aid is appropriate for all ages and helps people with different types of hearing loss.  

5. Receiver in the ear or receiver in canal

The two hearing aids have a similar style with behind the ear hearing aid. The receiver is inside the ear or canal.
