Temporal Resolution when Using Bone Conductive Sound in the Cases of Both Ears

Abstract

In this study, we measured and compared the time resolution of the air conduction and bone conductive sound transmission by measuring the gap detection thresholds. It was found that the time resolution of sound heard through bone conduction is worse than that of sound heard through air conduction. Better time resolution was found in both ears than in one ear, in both air conduction and bone conduction sound transmission. In bone conductive sound transmission, the differences in temporal resolutions between the cases of one ear in the cases of both ears were larger than the differences when using air conductive sound transmission.
