Abstract

DC60 (29/8/56) Automatic noise cancellation to enhance hearing quality during the use of the assistive device. Hear wirelessly It is an invention to improve the hearing quality during the use of a wireless communication aid consisting of transmitter and receiver. In which the receiver device section The audio signal received from the transmitting device is switched to the received environmental sound signal. From the device inside the receiver automatically Its working model is an automatic audio switching circuit that switches the audio signal received from the transmitting device to the received audio signal. Through the microphone inside the receiver device Before entering the process to select the signal So that users in the receiving device can hear the audio signal This increases the quality of hearing during the use of wireless communication aids. The audio signal from the transmitter device will be automatically switched to the environmental sound signal, with a working model of an automatic audio switching circuit. Act alternate The audio signal received from the transmitting device and the audio signal received through the microphone inside the receiving device before being processed so that the operator can hear the audio signal.
