    摘要： A wireless device (300) receives and captures multiple-channel audio signals and outputs the multiple-channel audio signals on at least one channel output stream (606). The wireless device (300) includes a microphone (401) for capturing a first audio channel and at least one speaker (402) for capturing additional audio channels. Each speaker has a switch (403) to enable the speaker to operate as an additional microphone for capturing at least one additional audio channel. The device also has a comparator (404), connected to a plurality of audio channels including the first audio channel and any additional audio channels, so that the comparator identifies which of the audio channels has a predetermined signal strength so as to identify one of the audio channels as a reference audio channel (406, 405). Additionally, in one embodiment, the comparator identifies which of the audio channels has a predetermined phase and identifies one of the audio channels as a reference phase channel (406, 405). The device also has an encoder (407) for receiving the plurality of audio channels to produce an output over at least one channel where the reference audio channel forms a reference signal and the audio channels other than the reference signal each form a delta signal from the reference channel.

    摘要： The invention concerns a method (200) and system (100) for selectively coupling a communication unit (110) to a hearing enhancement device (112). The method includes the steps of—in the communication unit—selecting (212) between an acoustic coupling setting and an inductive coupling setting, in response to the selecting step, switching (214) an audio output of the communication unit to an acoustic coupling path (136) or an inductive coupling path (138), and outputting (226) through either the acoustic coupling path or the inductive coupling path an audio signal to the hearing enhancement device.

    摘要： Systems and methods for pre-conditioning a received audio signal prior to audio equalization of the audio signal are provided. The system (100) includes a spectral tilt estimator (110) for estimating a spectral tilt of the received audio signal, and a compensative filter synthesizer (115) for synthesizing a compensative filter based upon the spectral tilt estimated by the spectral tilt estimator. The filter comprises at least one compensative filter coefficient for mitigating the spectral tilt of the received audio signal prior to audio equalization of the audio signal.
