Method and apparatus for level limitation in a digital hearing aid |
摘要 |
For level limitation of a time-discrete signal in a digital hearing aid having at least an input transducer, an A/D converter, a signal processing unit and an output transducer, the sampling rate of the time-discrete signal is boosted in the signal path following the A/D conversion and signal values of the time-discrete signal with a boosted sampling rate are limited to a maximum value. Harmonics that arise upon limitation of the signal values that are folded back into the audible frequency range are thus suppressed.
