Abrégé
(EN)
A hearing aid (200) comprises at least one microphone (210), a signal processing means (220) and an output transducer (230). The signal processing means is adapted to receive an input signal from the microphone. The signal processing means is adapted to apply a hearing aid gain to the input signal to produce an output signal to be output by the output transducer, and the signal processing means comprises means for adjusting the hearing aid gain by a direct transmission gain calculated for the hearing aid.

(ZH)

助听器(200)包括至少一个麦克风(210)、一个信号处理装置(220)和一个输出转换器(230)。所述信号处理装置适于接收来自所述麦克风的输入信号。所述信号处理装置适于将助听器增益应用到所述输入信号以产生将由所述输出转换器输出的输出信号,并且所述信号处理装置包括通过为助听器计算的直接传输增益调节所述助听器增益的装置。
