1. A method of emulating directionality of received auditory signals through conducted vibrations, comprising:

  • receiving an auditory signal via at least two microphones worn by a user;

    estimating a direction of arrival of the auditory signal relative to the at least two microphones;

    applying a phase and/or amplitude and/or delay shift to the auditory signal based upon the estimated direction of arrival; and

    vibrating at least a first and a second transducer to transmit the auditory signal through the bone of the user, wherein at least one of the first and second transducers vibrates a signal having the phase and/or amplitude and/or delay shift.
