What are Hearing Aids?

Hearing aids are small, wearable electronic devices that are designed to enable a person to hear sounds in an enhanced and better way, and understand the speech more clearly.

In terms of types and designs, these come in a wide variety of options, and can also be crafted and custom designed specific to an individual’s requirement.

How Hearing Aids Work?

Hearing aids work by amplifying sounds step-by-step:

  • The sound is received by the microphone of the hearing aid, which is then converted into a digital sign

  • The strength of this digital sign is increased by the amplifier

  • The speaker then passes the sound into the ear.

Hearing Aid Types

There are several types of hearing aids to choose from. Which one you choose is based on your level of hearing loss, your lifestyle, and your personal preferences.

Hearing Aid Components

Microphone

Hearing aids have a microphone that is sensitive enough to pick up on all the sounds around you. These sophisticated microphones can even differentiate between sounds. For example, they can identify which sounds are speech sounds you want to hear and which sounds are distracting background sounds you don’t want to hear. The microphone will also convert the sound waves into electrical signals and send them to the processor.

Processor

The most complex part of the hearing aid is the processor or amplifier. This is a small computer chip that can manipulate and change the electrical signals. When sounds reach the processor, they are changed to match your hearing. Certain sounds will be amplified while other sounds will be reduced. Any feedback or other interference is also reduced. If you have your tinnitus therapy program turned on, the processor also adds these features.

Receiver

Once the sound has been manipulated, the sound is sent to the receiver. This part of the hearing aid will convert the digital signals back into sound waves, create audible sound and direct that sound into your ears.
