Assistive Listening Devices
Have You Ever Had Difficulty Hearing or Understanding Speech:
- in meetings?
- in places of worship?
- in theaters or movies?
- in restaurants?
- with shopping transactions such as at a pharmacy or bank?
- in public places such as airports or municipal buildings?
In those situations, an assistive listening device can help.
Assistive listening devices (ALDs) expand the functionality of hearing aids and cochlear implants by helping you separate the sounds you want to hear from background noise, and by enabling you to hear when the speaker is more than a few feet away.
The speaker talks into a microphone and the speech are sent straight to your ear, thus avoiding the degrading effects of noise and distance on speech intelligibility. It’s really that simple.
An assistive listening device consists of a microphone to collect sound, a transmitter to send the signal across a distance, a receiver to intercept the signal, and any one of several different listening attachments to send the sound from the receiver to the user’s ear, hearing aid, or cochlear implant.
