Social Alarm System with inductive loop amplifier to reduce level of a non priority audio signal received in a hearing aid in response to the alarm condition

摘要

A social alarm system is not always heard when an inductive loop system is being used. A social alarm system which establishes communication between a client and an operator at a remote operating location comprising an inductive loop amplifier (210) is provided having several non-priority input ports (212) and a priority input port (214). The inductive loop amplifier (210) is arranged to reduce an output level of at least one audio signal received on at least one of the non-priority input ports in response to an alarm signal. In this way, interfering noise from the non-priority input ports (212) (from e.g. the TV or radio etc) can be eliminated in an emergency. Embodiments include a client unit comprising an alarm generating unit, a communication unit arranged to provide an audio communication path with a remote communication terminal when an alarm is generated and receive an audio signal from the remote communication terminal, and an output port arranged to output the audio signal received from the remote communication terminal to a remote device.
