Abstract
Official abstract text for this publication.
A signal processing device includes a noise analysis unit for analyzing a frequency component of a noise signal obtained by converting a collected sound into an electrical signal, a plurality of filtering units for carrying out predetermined filtering operations on the noise signal on the basis of an analysis result, and an output control unit for temporally varying a synthesis rate of outputs of the plurality of filtering units according to a change in the analysis result of the noise analysis unit. When the analysis result of the noise analysis unit changes, one filtering unit starts a predetermined filtering operation by characteristics different from those of other filtering units that carry out predetermined filtering operations on the noise signal according to the change in the analysis result of the noise analysis unit.
First claim
Opening claim text (preview).
The invention claimed is: 1. A signal processing device comprising: a noise analysis unit for analyzing a frequency component of a noise signal, obtained by converting a collected sound into an electrical signal, over time and outputting an analysis result that changes over time according to changes over time in the noise signal; a plurality of filtering units each for carrying out a different fixed predetermined filtering operation on the noise signal, each corresponding to an…
