Abstract:
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, wherein the at least two microphones are intra-buccal to the 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 with an oral appliance removably positioned along one or more teeth without requiring anatomical modification of the one or more teeth and without bonding to the one or more teeth of the user such that the appliance produces an interference fit between the apparatus and at least two surfaces of the one or more teeth, wherein at least one of the first and second transducers vibrates a signal having the phase and/or amplitude and/or delay shift.
