Hearing Aid Terminology

Understanding Hearing Aid Terminology

Hearing aid terminology can be confusing and the array of features may be overwhelming when you are trying to select the best hearing aids for you.

Below are definitions of common hearing aid features to help you better understand your options when choosing hearing aids that are right for you.

  • Adaptive Directional Microphones can follow moving sounds or reduce several different sounds at the same time.

  • Automatic Program Switching enables the hearing aid to change between programs or memories depending upon the listening environment.

  • Bluetooth Compatibility allows hands-free use of compatible wireless devices like cell phones.

  • Direct Audio Input enables the hearing aid to receive input from another device such as a TV or personal entertainment system.

  • Directional Microphones are more sensitive to sound approaching from one direction, such as the front, while minimizing unwanted sounds from other directions. This feature is helpful for conversing in noisy situations, such as restaurants.

  • Feedback Suppression reduces feedback (that annoying whistling sound) that is the number one complaint people have about hearing aids. Most hearing aid wearers experience feedback when they put their hand over their ear or use the phone.

  • FM Integration allows the hearing aid to receive signals from an FM transmitter. The transmitter can be given to a speaker, like a teacher in a classroom, to isolate the speaker’s voice for the hearing aid wearer.

  • Impulse Sound Management provides protection from sudden loud sounds.

  • Noise Reduction automatically alters the response of the hearing aid in noisy situations.

  • Programs are different settings or memories for different situations such as quiet places, noisy places, and telephone use. Advanced hearing aids can have memories that are automatic or a combination of both manual and automatic.

  • Remote Control is an optional accessory with some hearing aids that allows the wearer to discreetly make adjustments.

  • Speech Enhancement technology allows hearing aids to detect certain frequencies within each sound of speech and provide extra amplification to those frequencies.

  • Telecoil amplifies sound from the telephone or loop amplification system without picking up background noise, which helps prevent feedback.

  • Toggle/Button control allows the hearing aid wearer to manually change programs for different listening environments.
