What is a Hearing Aid

A hearing aid is an electronic device that amplifies sound at different levels for different pitches. Hearing aids consist of a microphone, amplifier and receiver.

  • Microphones - Electronic devices that pick up sound (an acoustical signal) and changes it to an electrical signal in the hearing aid.  There are several types of microphones which can be used in hearing aids. Some microphones can assist with listening in background noise. Ask an audiologist for more information.

  • Volume Up/Program Button -  Used to increase the volume of the hearing aid, it is also used to select different pre-determined programs that have been set up in the hearing aid.

  • Volume Down/Program Button - Used to increase the volume of the hearing aid, it is also used to select different pre-determined programs that have been set up in the hearing aid. 

  • Indicator Light - Different colors will mean different things, ask your audiologist to list what each color means.

  • Battery Door - This is where the hearing aid battery will be inserted, pediatric hearing aids have a locking door to protect your child from accessing the battery.

  • Ear Hook - A plastic attachment that connects to the hearing aid and loops over the top of the ear. The ear hook attaches the hearing aid to the tubing which attaches to the ear mold which is inserted into the ear.

  3. Place hearing aid in battery.

Battery care:

  • Store batteries in a cool, dry place. Exposure to extreme temperatures will shorten their life.

  • Keep away from children and pets, as batteries are toxic.  Battery Ingestion Hotline: (202) 625-3333
