使音频信号频率失真的方法和根据该方法工作的听力装置
摘要：
本发明涉及一种使音频信号频率失真的方法和根据该方法工作的听力装置。给出了用于使作为音频信号存在的输入信号(Ek)频率失真的方法以及相关的听力装置(2)。将输入信号(Ek)分成低频信号分量(NF)和高频信号分量(HF)，其中，这两个信号分量(NF，HF)在边界频率(fg)处彼此交界。使高频信号分量频率失真，并且与低频信号分量叠加，以形成输出信号(A)。至少对于包含边界频率(fg)的高频信号分量(HF)和/或低频信号分量(NF)的边缘区域(RH，RL)，改变相关联的放大因子，使得低频信号分量(NF)的信号水平(L1)和频率失真的高频信号分量(HF)的信号水平(L2)之间的水平差(ΔL)增大。
摘要（英）：

The invention relates to a method for distorting the frequency of an audio signal and a hearing apparatus operating according to this method. A method that distorts the frequency of an input signal (Ek) that is present as an audio signal and a related hearing apparatus are provided. Here, the input signal (Ek) is divided into a low-frequency signal component (NF) and a high-frequency signal component (HF). These two signal components (NF, HF) adjoin one another at a cut-off frequency (fg). The high-frequency signal component is frequency-distorted and overlaid with the low-frequency signal component to form an output signal (A). An associated gain factor is modified at least for an edge region (RH, RL), containing the cut-off frequency (fg), of the high-frequency signal component (HF) and/or of the low-frequency signal component (NF), such that a level difference (deltaL) between a signal level (L1) of the low-frequency signal component (NF) and a signal level (L2) of the frequency-distorted high-frequency signal component (HF) is increased.
