AB  - In this paper the bone-air differential transfer function (BADTF) is defined as the difference between the bone conduction (BC) and the air conduction (AC) transfer functions. This can be equivalent to the bone to air hearing threshold gap when the system is linear. The single ear BADTF was measured at 29 frequencies ranging from 0.5 to 8 kHz with 5 normal hearing subjects. Repeatability of this method was also verified. The results show that there are obvious individual differences but all the curves have similar envelopes. With the BADTF, the individual equalization can significantly improve the performance of the BC reproduction at low frequencies and make the BC sound perceived closer to the target timbre.
