A wireless transmission system for substantially noise-free transmission including a portable, battery powered, self contained transmitter for transmitting signals representative of an audio input to a remote receiver. The transmitter includes noise reduction encoding circuitry for processing a transduced audio input signal and providing a processed output signal to a transmission unit for transmission to the remote receiver. The remote receiver receives the transmitted signals and supplies the received signals to a reception unit including noise reduction decoding circuitry for processing the received signal and providing an audio signal output with improved signal to noise ratio to a utilization device.
