A device for analysis and filtration of sound which comprises at least one frequency-linear filter, at least one frequency-logarithmic filter and a weighting means for the combining and non-linear weighting of the output signals from the frequency-linear filter and the frequency-logarithmic filter. The sound is fed parallel as an input signal to the two sets of filters. In turn, the output signals from the filters are fed to the weighting means where they are combined and weighted non-linearly on the basis of magnitudes relevant to the sound. A decision with respect to the identity of the sound is made in a decision means. The invention also relates to a method for analyzing and filtering sound with the aid of the above-mentioned device.
