| 摘要 |
The invention relates to a bone conduction hearing aid system, comprising: a right ear microphone arrangement (12A) and a left ear microphone arrangement (12B); a right ear signal processing unit (14A) and a left ear signal processing unit (14B) for processing the audio signals captured by the right ear microphone arrangement and the left ear microphone arrangement, respectively, from ambient sound; a right ear bone conduction output transducer (16A) for stimulating the user's right ear cochlea (20A) according to right ear output audio signals, and a left ear bone conduction output transducer (16B) for stimulating the user's left ear cochlea (20B) according to left ear output audio signals; a right ear cross-talk compensation filter unit (18A) for generating a right ear cross-talk compensation signal from the processed audio signals of the right ear signal processing unit according to an estimated transcranial transfer function (B12) from the right ear bone conduction output transducer to the left ear cochlea, and a corresponding left ear cross-talk compensation filter unit (18B); and means (22A, 28B, 30A, 30B, 32A, 32B) for subtracting the left ear cross-talk compensation signal from the processed audio signals of the right ear signal processing unit in order to generate the right ear output audio signals, and means (22B, 28B, 30A, 30B, 32A, 32B) for subtracting the right ear cross-talk compensation signal from the processed audio signals of the left ear signal processing unit in order to generate the left ear output audio signals. |
