ABSTRACT:
An audible environment awareness restoring device allows a person to perceive, through his sense of touch, audible sounds corresponding to the human voice. A bone conduction speaker or transducer is mounted against a person's body, preferably against the sternum. An audio signal from one or more microphones is fed to the bone conduction speaker or transducer which converts the audio signal to vibrations. The bone conduction speaker or transducer transmits the vibrations to the person's rib-cage which will then resonate in synchronism with the input audio signal.
