Impressive multiprogrammable hearing instruments have been in use for several years. They are programmed to suit each user's ear by a trained audiologist. A remote control unit stores several different programmed prescriptions for particular environments. The touch of a button easily adjusts the hearing aid to a noisy concert, a restaurant, a quiet picnic in the country or other environment. Contemporary improvements over conventional hearing aids are significant.
Users can easily discern speech despite the usually taxing background noise.
And the devices can be reprogrammed as hearing loss changes with time. Other assistive hearing devices also help the impaired to function more easily in home and public environments. A microphone is placed close to the sound source and the signal is carried to the receiver via light waves or radio frequencies. Sound amplifiers, louder bells and lights that flash when the phone rings can all improve telephone communication. All rights reserved.
