  • Variable gain amplifier controlled by ambient noise level
    Patent number: 3934084
    Abstract: An audio amplifier system is provided comprising a variable gain amplifier adapted to receive an input signal, means for detecting periods when the input signal falls below a predetermined level, and sound transducer means arranged to provide a signal proportional to the sound level in the area or part thereof covered by the system for controlling the gain of the amplifier. An inhibitor is provided which is arranged to be controlled by the detecting means so as to prevent any change of the gain of the variable gain amplifier except during periods when the input signal falls below the said predetermined level.
    Type: Grant
    Filed: March 27, 1974
    Date of Patent: January 20, 1976
    Assignee: Television Research Limited
    Inventors: Robert Thomas Munson, Philip Hodgson
