摘要： PROBLEM TO BE SOLVED: To provide an apparatus for suppressing sound-signal amplitude, which gives very small quality deterioration of reproduced sounds even if strong amplitude suppression is taken place. SOLUTION: When the sound-signal waveform variation shifts toward a large direction, the amplitude is compressed in a logarithmic or logarithmic-like manner. When the direction of the signal waveform variation reverses, the compression action is stopped, and the continuing waveform is output starting from the amplitude level shown at the stoppage of the compression action. If the amplitude variation shifts toward a large direction again, the logarithmic compression or logarithmic-like compression is started, and such processes are repeated. By performing gradual amplitude suppression of the sound signal, harmonic distortion components are reduced. COPYRIGHT: (C)2010,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To enhance the apparent performance of an acoustic apparatus by generating a sound signal from which a reproduced sound with a less sense of distortion is obtained even when the amplitude of the sound signal is considerably limited, and to enhance the capability of every apparatus for processing the sound signal, and generates a sound signal easily heard by ears of people by the similar method so as to enhance the sound quality of hearing-aids and recorders or the like.

Exception of the sound signals whose frequency is the particular frequency or over is provided because of reducing production of harmonics offensive to the ears. COPYRIGHT: (C)2006,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To improve an apparent capability of an acoustic apparatus by producing an audio signal to obtain a reproduced sound of a little distortion even if an amplitude of a large-amplitude signal is strongly suppressed, and also to improve performance of an apparatus dealing with audio signals, such as a high-quality hearing-aid by converting an audio signal detected by a microphone through a similar method into a signal to obtain a reproduced sound of a sound volume feeling that human ears feel like a natural sound, and using such a sound. SOLUTION: A small-amplitude signal is kept as it is, and amplitude suppression is performed on a low-frequency and great-amplitude audio signal. However, amplitude suppression is not performed so much on a signal as its frequency increases. COPYRIGHT: (C)2006,JPO&NCIPI

The delay circuit 4 receives the sound signal and carries out delay processing to synchronize the output signal from the low pass filter with the received sound signal. The post-stage subtractor 5 receives the output signal from the delay circuit, subtracts the output of the low pass filter from the received output signal from the delay circuit, and provides an output of the subtraction result.
