A transmitter connected to a sound system which provides hearing enhancement to a receiver.
a device that assists a person to receive auditory information, usually designed for a specific situation. See assistive listening devices (ALDs) for people with hearing loss.
Technical tool to assist hard of hearing people, with or without a hearing aid. It brings the speakers voice directly to the ear. Helps to overcome the problems of distance and surrounding noise.
A large variety of devices designed to improve the ability of a person to hear in specific listening situations.
A class of hearing instruments designed to increase the signal to noise ratio between the listener and the speaker. Such examples are FM systems that transmit via FM wave bands, infared systems that transmit via infared signal, personal amplifiers, telephone amplifiers, amplified or vibrating alarm clocks, alerting (flashing) fire alarms.
An electronic or mechanical aid to hearing. The device or system enhances the reception of auditory signals. These devices are used by people who are deaf or hard of hearing to facilitate understanding of spoken language. A normal tone of voice should be used by the speaker when communicating with such devices. Types generally referred to are the loop system, the FM system, and the infrared system.
An electronic device that provides amplification of sound to a hearing impaired person. Device include personal hearing aids, magnetic induction loops, FM radio systems and infrared systems. All have advantages and disadvantages and some may be dependent on good acoustical environment for optimal performance.
A device used to help someone hear (ex. Amplified telephone or T.V. listening device) or know that an important sound is being presented (ex. A light that blinks when someone is at the door or a strobe smoke detector that flashes when a fire alarm sounds).
Composed of a microphone, transmitter component, receiver, and an earmold; amplifies only the sound source picked up by the microphone.
