发明名称 Hearing apparatus with passive input level-dependent noise reduction
摘要 A hearing apparatus and in particular a hearing device is to be provided, in which interference noises are to be reduced however as natural an acoustic image as possible is consequently retained. To this end, a hearing apparatus with a first signal processing channel, into which a noise reduction device is integrated and a second signal processing channel, which has the same input as the first signal processing channel and into which no noise reduction device, but instead a level limitation device is integrated, is proposed. An adding device adds the output signals of both signal processing channels to form an overall output signal. A passive input level-dependent noise reduction can thus be realized, with which quiet signals can be heard again despite the noise reduction.
