Claim 11:
12. The method of claim 1, wherein the frequency band components are extracted as frequency band bin components, and each frequency band is a frequency bin, and wherein step g) comprises:
g1) for each frequency band, determining a preliminary gain from a comparison between an acoustic level of the extracted frequency band component of said frequency band and the second acoustic level threshold associated with said frequency band,
g2) detecting a plurality of local minima over acoustic levels of frequencies in the frequency band components,
g3) grouping together frequency bands located between two local minima to form a plurality of frequency groupings,
g4) for each grouping, determining a reduction gain of the grouping corresponding to a lowest preliminary gain among the preliminary gains of the frequency bands of said grouping,
g5) affecting the reduction gain of the grouping to each one extracted frequency bands of said grouping.
