摘要
A microphone (1) collects the sounds and passes the signals to an amplifier (2) or to an FM transmitter/receiver. The voltage output can be passed to a loudspeaker or to electrodes (3) placed on the arm of the deaf person. The low level voltage sensed by the person can be interpreted as speech by the brain. ADVANTAGE - Allows those who are hard of hearing due to inner nerve to sense sound received.
