How Hearing Aids Work-The Four Vital Components of A Hearing Aid

Hearing aids are little electronic devices that are designed to amplify sounds.  Hearing aids can help hearing impaired people to be able to hear many of the sounds they cannot hear on their own.  Hearing aids are straightforward devices with four vital components. 

This is how hearing aides work.  A microphone captures sounds from the environment and transforms them into electronic signals.  Then, the signals are sent to the amplifier.  The amplifier raises the volume of the sounds and transmits the sounds to the receiver.  The receiver transforms the electronic signals back into sounds and sends the sounds back to the ear and then to the brain. 

Hearing aids work on battery power.  Hearing aids are not able to help everyone that suffers from hearing loss.  Hair cells in the ear help hearing aids to work.  The hairs pick up the vibrations that the hearing aid sends and then transforms the vibrations into nerve signals. 

If a person does not have any hair cells in their inner ear, the hearing aid will not work for them.  So, a hearing aid is basically a sound amplifier.  This is the reason why people suffering from hearing loss can hear many different sounds that they cannot normally hear unless they are using a hearing aid.  There are two different types of hearing aids.  There are digital hearing aids and analog hearing aids.

Analog hearing aids can be either programmable or conventional.  A programmable analog hearing aid has features that can be programmed to adjust to different environments.  The features can be activated with an on switch or a remote control. 

Digital hearing aids work in a similar way as the programmable analog hearing aids.  The key difference is that the digital hearing aids have a self-adjusting feature in place of the manual setting feature on the programmable hearing aids.  Digital hearing aids cost a lot more money than both the programmable and conventional analog hearing aids.

How hearing aids work also depends on the style of the hearing aid.  The most popular styles are the behind the ear (BTE), in the ear (ITE), in the ear canal (ITC) and completely in the canal (CIC).  Their names describe how they fit in or on the ear.  The amount of hearing loss helps to determine which style will be the most effective. 

The BTE hearing aids are simple to use and maintain, but they are easy to detect.  This style is recommended for children because the hearing aids are easier to use.  The ITE style sits inside the ear and is almost unnoticeable.  It has more features than the BTE hearing aid.  Both the ITC and CIC have similar features as the ITE.
