Types of Hearing Technology


Hearing Aids

Hearing aids are small electronic devices worn in or behind your ears. They make some sounds loud so that those with hearing loss can listen, communicate, and participate more fully in daily activities. Hearing aids help people hear better in both quiet and noisy situations.

Hearing aids have three basic parts: a microphone, amplifier, and speaker. Hearing aids receive sound through a microphone, which converts the sound waves to electrical signals and sends them to an amplifier. The amplifier increases the power of the signals and then sends them to the ear through a speaker.

Advanced technology has additional functionality to address situations such as background noise or feedback. Miniature computerization provides more features and better sound processing – this means clearer listening with less interference from unwanted sounds.


You may benefit from hearing aids if:

  • Your hearing frustrates you when you converse with family or friends
  • Your spouse tells you he or she often has to repeat what was said.
  • Your hearing problem causes embarrassment.
  • You have difficulty hearing the TV or radio at a normal volume level.
  • Your hearing causes you to have arguments with family members.
  • You feel that hearing difficulties hinder your social life.
  • You attend religious services or group activities less than often because of your hearing.
  • It is difficult for you to understand when someone speaks to you in a whisper.
  • Your hearing creates difficulties when you visit a restaurant with friends or family.
