Abstract :
The Bone-conducted ultrasound (BCU) technique is quite promising for the hearing aid. Here an experiment platform is presented for the BCU hearing, which is based on a DSP system. Various voice modulation methods can be carried out on this platform by programming. The hardware architecture and the algorithm are described in detail. It provides an experiment platform which is quite reliable and flexible for our BCU hearing studies.
