摘要： Level compression applied to the acoustic signals (18) received by a binaural hearing aid system (1) counteracts the preservation of inter-aural level differences (ILD) and thereby reduces the user's ability to locate the sound source and consequently his or her ability to understand speech in noisy environments. It is therefore known to increase the gain (57) in the hearing aid (2) receiving the louder signal and/or decreasing the gain (58) in the hearing aid (3) receiving the quieter signal, which at least in part allows for preserving the ILDs. However, in some situations this instead reduces the user's ability to understand speech, e.g. when acoustic noise is received at one ear (4) at a higher level (53, 54) than simultaneous speech at the other ear (5). The present invention overcomes this problem by decreasing the gain (57) in the hearing aid (2) receiving the louder signal and/or increasing the gain (58) in the hearing aid (3) receiving the quieter signal, when the difference between the noise-floor levels (55, 56) of the two hearing aids (2, 3) increases.
摘要翻译：施加到由双耳助听器系统（1）接收的声学信号（18）的电平压缩抵消了听觉间水平差（ILD）的保留，从而降低了用户定位声源的能力，并因此降低了他或她的能力在嘈杂的环境中理解言语。因此，已知增加接收较大信号的助听器（2）中的增益（57）和/或减小接收更安静信号的助听器（3）中的增益（58），该增益（58）至少部分允许保留ILD。然而，在某些情况下，这反而降低了用户理解语音的能力，例如当在一个耳朵（4）处接收到比在另一个耳朵（5）处的同时语音更高级（53,54）的声学噪声时。本发明通过减少接收更大信号的助听器（2）中的增益（57）和/或增加接收更安静信号的助听器（3）中的增益（58）来克服该问题，两个助听器（2,3）的噪音底层（55,56）增加。

摘要： A hearing aid includes an audio signal input device, a signal processor and a signal output device which presents a processed audio signal perceivable as sound to an ear of a user. The signal processor includes fast acting level estimators and slow acting level estimators. A communication link between two hearing aids at each ear of a user allows the transmission between the two hearing aids of level estimates from the slow acting level estimators.
