Apparatus for noise recognition and noise separation |
摘要 |
The arrangement includes at least one normalization unit (13) which normalizes respectively an amplitude (12) of a certain frequency range from the spectrum of the acoustic signal (1). A differentiation arrangement (15) differentiates the normalized amplitude (14) to time, and forms an absolute value of the differentiated amplitude. A neural network (18) includes input neurones which receive the differentiated amplitude or its absolute value of the certain frequency range, and output neurones which form a classification signal (22) classifying the acoustic signal according to its frequency spectrum, giving an indication of the type of acoustic signal. |
