<p>Equalizing/filtering device associated with a reproduction and/or amplifying system which dynamically changes its frequency response in the time domain in connection with the amplitude variation of the input or output signal from the said device or the sound pressure listening level to the aim of taking into account the non-linearity of the response of the human ear at the variation of said parameters. The frequency response of said equalizer/filter if therefore calculated according to the audiometric diagram curves normal to the human's ear (figure 1) which reproduce the frequency response to the ear itself. <IMAGE></p> |
