Learn how adaptive hearing aid directionality can help you hear speech in the presence of noise

How Hearing Aids Work
Hearing aids are tiny electronic devices that sit in or behind your ear. Hearing aids receive sound, process and amplify it, and deliver it right into your inner ear, where it is sent to the brain.

  •  When a person speaks, the hearing aid microphone picks up the sound to convert it into electrical signals
  •  The hearing aid amplifier increases the strength of the electrical signal
  •  The hearing aid receiver/speaker converts the electrical signal back into sound and sends it to the inner ear
  •  The brain “hears” and understands the sound as speech

Hearing aids are sophisticated, state-of-the-art instruments with many different features and benefits. The appropriate style for you depends on your level of hearing loss, lifestyle and budget.
