摘要： Architectures of numbers of microphones and their positioning in a device for sound source direction estimation and source separation are presented. The directions of sources are front, back, left, right, top, and bottom of the device, and can be determined by amplitude and phase differences of microphone signals with proper microphone positioning. The source separation is to separate the sound coming from different directions from the mix of sources in microphone signals. This can be done with blind source separation (BSS), independent component analysis (ICA), and beamforming (BF) technologies. The device can perform many kinds of audio enhancements for the device. For example, it can perform noise reduction for communications; it can choose a source from a desired direction to perform speech recognition; and it can correct sound perceiving directions in microphones and generate desired sound images like stereo audio output. In addition, with source separation, 2.1, 5.1, 7.1, and other audio encoding and surround sound effects can be straightforward.

摘要： A method of operating a hearing system for conducting telephone calls as well as a hearing system capable of performing the proposed method. The hearing system includes a communication device (4) with a communication device microphone (3′) for picking up a first sound signal and providing a primary sidetone signal. The hearing system further includes a hearing device with a hearing device microphone for picking up a second sound signal and providing a secondary sidetone signal. A first amplification is applied to the primary sidetone signal and a second amplification is applied to the secondary sidetone signal. Adjusting of the first amplification is dependent on adjusting of the second amplification, or alternatively, adjusting of the second amplification is dependent on adjusting of the first amplification. The primary and secondary sidetone signals are then combined and subsequently output by a hearing device loudspeaker.

摘要： Provided is a signal processing system in which a plurality of programs are not required to be stored in advance. A CPU 12 reads a predetermined sound signal processing program from a non-volatile memory 14 and transmits the program to each microphone unit via a communication I/F 11. The sound signal processing program transmitted from a host device 1 is temporarily stored in a volatile memory 23A via a communication I/F 21A. A sound signal processing section 24A performs a process corresponding to the temporarily stored sound signal processing program and transmits a digital sound signal relating to the sound picked up by a microphone 25A to the host device 1. For example, in the case that an echo canceller program was transmitted from the host device 1, the echo component in the sound picked up by the microphone 25A is removed and the resultant sound is transmitted to the host device 1. The sound signal processing program temporarily stored in the volatile memory 23A is erased in the case that power supply to a microphone unit 2A is shut off. At each startup, the microphone unit surely receives a sound signal processing program for operation from the host device 1 and performs operation.
