ABSTRACT:
A remote sound monitor includes a receiver unit and a transmitter unit. The transmitter unit includes a sound transducer that receives the sound input and converts the sound input to the audio signal, and an audio transmitter that transmits the audio signal. The receiver unit includes an audio receiver that receives a transmitted audio signal having a parameter that corresponds to an amplitude of a remote sound input, and a display that provides a visual indication of the parameter of the audio signal. The display providing the visual indication can flash, strobe, or change colors in response to a change in amplitude of the sound input. The receiver unit can also include an audio speaker with a user-actuated amplification stage to provide remote audio output of the sound input.
