Abstract (en)
[origin: WO0057673A1] Bass audio signals can give an annoyance of neighbors (non-voluntary listener) of the listener (voluntary listener). To overcome this band block filters are known, but by blocking the audio signals in the frequency band the perception for the listener is less good. The invention overcomes this problem by combining enhancing means to obtain the so-called ultra bass, with the blocking filter.
