The efficiency of the sound transmission of a bone-conduction hearing aid is improved when tooth is excited by a transducer because the vibration generated by the transducer is not attenuated by the damping of skin and directly transmits to the skull. In addition, if sound localization is established by a binaural bone-conduction hearing aid, speech articulation is also improved. In this study, the sound localization was tested by applying sinusoidal signals to two transducers attached to right and left teeth. The pattern of the sound localization according to the phase difference between the two signals depended on individuals, and this sound localization seemed to be caused by the change of the amplitude of the vibration transmitted to the cochleae from the transducers.
