Abstract
Systems and methods for transmitting an audio signal through a bone of a user includes receiving an audio signal from a first microphone positioned at an entrance or in a first ear canal; and vibrating a first transducer to audibly transmit the audio signal through the bone. A second microphone can be positioned in a second ear canal and the two microphones preserve and deliver inter-aural sound level and phase differences that naturally occur so that the user can perceive directionality.
