Hearing Aid Technology
The following are definitions of features commonly found in hearing aids. Features may be standard or available as an option for an additional charge, depending upon the hearing aid model and style.
Your hearing care provider will discuss the features that may be most useful for you, depending upon your individual hearing loss and lifestyle.
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. Adaptive directional microphones can follow moving sounds or minimize unwanted sounds.
Adaptive Directional Microphones can follow moving sounds or reduce several different sounds at the same time minimizing unwanted sounds.
Feedback Suppression reduces feedback (whistling sound), which is sometimes a complaint people have about hearing aids. Hearing aid wearers may experience feedback when putting their hand over the ear or using 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 and is most useful with reducing steady noise, such as fans, motors, etc.
Programs are different settings or memories within the hearing aid for various situations such as quiet settings, noisy places, and telephone use. Advanced hearing aids have memories that are automatic or a combination of both manual and automatic. This allows the user to select particular listening preferences, depending on the situation.
Remote control is an optional accessory with some hearing aids that allows the wearer to discreetly make adjustments. It is also convenient for those with dexterity issues.
Speech Enhancement technology allows hearing aids to detect certain frequencies within each sound of speech and provide extra amplification to those speech sounds. This makes speech clearer and easier to understand.
Telecoil amplifies sound from the telephone or loop amplification system without picking up background noise. This results in better hearing on the phone. Telecoils may be used in public facilities such as churches and theaters to improve clarity when available.
Toggle/Button control allows the hearing aid wearer to manually change programs for different listening environments.
