Abstract (in Japanese) (See Japanese page) 
(in English) We propose an implanted hearing aid that is worn in the crown of a dental implant and uses the mechanism of bone conduction. In this study, we measured the thresholds of bone conduction hearing via the teeth using a bone conductive actuator. Subjective evaluations were performed based on subject’s minimum audible value as a method of measuring the bone conduction sound hearing level during tooth excitation. This work clarifies that there is a correlation between the minimum audible value at the time of tooth excitation and the measured results of the in-ear air conduction sound using the in-ear probe microphone. The air conduction sound generated within the ear by changing the tooth excitation position was measured with an in-ear probe microphone.
