Abstract

We can hear the sounds transmitted differently. One is air-conducted sound through our ears. The other is bone-conducted sound transmitted through bones and soft tissues. When the bone-conducted hearing test is examined for the help of diagnoses, the vibrator for bone conduction is brought into contact with the mastoid behind the ear, and the threshold levels of bone-conduction are examined. In this study, we distinguished "teeth-conduction" from bone-conduction, and measured the pure tone threshold levels of air conduction, bone conduction via the mastoid and teeth conduction via anterior teeth on the upper and lower jaws using an audiometer. The results showed that all participants perceived teeth-conducted sounds. Characterizing the sound of the teeth conduction may help understand the tooth-drilling sound's discomfort and the satisfaction when eating food.
