在降噪控制器34仅应用反馈传递函数H的缩放的情况下，则宽带增益G的减小ΔG等于滤波器缩放因子的乘法逆。
In the case that the noise cancellation controller 34 applies only a scaling of the feed-backward transfer function H, then the decrease ΔG of the wide-band gain G equals the multiplicative inverse of the filter scaling factor.

In feed-backward noise cancellation earphones, such as the one described above, the noise cancellation signal path 37 is typically part of a closed signal loop that includes an electroacoustic transducer 23 that provides an audio output signal So, a relatively short acoustic path from a sound-producing element of the electroacoustic transducer 23 to a sound inlet of a reference microphone (the feed-backward microphone 26) that picks up the audio output signal SO and ambient sound SA (possibly passively attenuated by structural components of the earphone) and provides a reference signal SR, a noise cancellation filter 32 that filters the reference signal SR to provide a noise cancellation signal Sc and an output unit 33 that combines the noise cancellation signal Sc with an audio input signal SI to provide a driving signal SD for the electroacoustic transducer 23.
在这种耳机中，音频输出信号SO通常支配参考信号SR。
In such earphones, the audio output signal So often dominates the reference signal SR.

Since in feed-backward noise cancellation earphones and feed-forward noise cancellation earphones, the functional components are quite similar, the figures and the corresponding parts of the description illustrate both types, and in the present application, identical reference numbers and labels are thus used to designate similar components, signals and properties for both types of ANC systems.
在前馈降噪耳机中，降噪信号路径37通常是包括参考麦克风26的开放信号回路的一部分，然而具有声音入口，该声音入口布置有来自电声换能器23的发声元件的更长和/或声学衰减的声路径，例如在外壳21的外部，使得其主要拾取环境声音SA以提供参考信号SR，以及对参考信号SR进行滤波以提供降噪信号SC的降噪滤波器32，以及将降噪信号SC与音频输入信号SI进行组合以提供用于电声换能器23的驱动信号SD的输出单元33。
In feed-forward noise cancellation earphones, the noise cancellation signal path 37 is typically part of an open signal loop that includes the reference microphone 26, however with a sound inlet arranged with a longer and/or acoustically attenuated acoustic path from the sound-producing element of the electroacoustic transducer 23, e.g. at the outside of the housing 21, so that it primarily picks up ambient sound SA to provide the reference signal SR, as well as the noise cancellation filter 32 that filters the reference signal SR to provide a noise cancellation signal SC and the output unit 33 that combines the noise cancellation signal Sc with the audio input signal SI to provide the driving signal SD for the electroacoustic transducer 23.
在这种耳机中，环境噪声SA通常支配来自参考麦克风26的参考信号SR。
In such earphones, the ambient noise SA often dominates the reference signal SR from the reference microphone 26.

In the prior art, various known methods exist for adaptively determining the transfer functions H for the respective noise cancellation filters 32 of feed-backward noise cancellation earphones and feed-forward noise cancellation earphones.
具有反馈降噪的耳机和具有前馈降噪的耳机之间的主要区别在于参考麦克风26的布置以及用于确定降噪滤波器32的传递函数H的方法。
The main differences between earphones with feed-backward noise cancellation and earphones with feed-forward noise cancellation lie in the arrangement of the reference microphones 26 and in the methods used for determining the transfer functions H for the noise cancellation filters 32.
