First Claim
Patent Images
1. A combination hearing protector/communication system assembly that attenuates undesired external sounds and delivers audio to the user, comprising:
- a first hearing protecting muff for attenuating sounds and receiving desired acoustic signals, the muff enclosing an optical transmitter for transmitting optical signals representative of the received acoustic signals; and
an ear-plug assembly including an optical receiver for receiving the transmitted optical signals and a transducer for providing acoustic signals representative of the acoustic signals received by the muff.

Abstract
A hearing protector assembly has a muff and an ear-plug for hearing protection while allowing reception of audio communication. The muff has a receiver for audio signals, a modulation circuit, and a set of LEDs for transmitting the audio signal as a light signal. The ear-plug has a photovoltaic cell for receiving the light signals, a demodulator circuit, and a transducer for converting the received signal into an acoustic signal.
