Hearing aids are electronic devices that pick up and amplify sound. By amplifying sound, sounds that the wearer normally would not hear are increased in volume and therefore better delivered to the ear.

There are many different degrees and types of hearing impairment. Technology has paved the way for many innovative hearing devices designed to improve a broad range of hearing impairments.

Hearing Aid Components:

  • Microphone(s): Gathers sound and converts it to electrical impulses. Sometimes, more than one microphone is in the hearing aid. Different microphones allow the hearing aid to pick up sound from different areas.
  • Amplifier: Used to increase the strength of the electrical impulses.
  • Receiver: Transforms the electrical impulses back into sound waves and redirects them into the ear of the wearer.
  • Battery: Needed to supply the energy source.

Other Components:

  • There may be switches on the aid that turn the device on or off, allow for telephone usage or provide the ability to control volume.
  • A computer chip is found in all digital hearing aids.
  • Multiple programs offer various sounds for a variety of listening environments. As an example, one program may be for conversations, another for the telephone and a third for noisy situations. An aid can come with numerous programs. The wearer may manually change back and forth between different programs, while some aids switch automatically.
  • Hearing Aid Evaluation, Dispensing
