Claim 5:
6. The apparatus (100) according to claim 5, wherein said shape parameter or said shape parameters is/are selected from the group consisting of:
an area (53) defined by said average frequency spectrum in a predetermined range of frequencies (54) and/or in a predetermined range of amplitudes (55);
a width (54) of said average frequency spectrum at a predetermined amplitude level (56), in particular at a level defined by an amplitude value (56) lower than a maximum value (57) of said average frequency spectrum by a predetermined amount, in particular by 3 dB or by 1 db;
a frequency (58) corresponding to a maximum value (57) of said average frequency spectrum;
a slope (59) of a line (60) that interpolates a plurality of points (61) of said average frequency spectrum in a predetermined range of frequencies (62);
the coefficients of a polynomial that interpolates points (66) of said average frequency spectrum in a frequency range (54) that contains a frequency (58) corresponding to a maximum value (57) of said frequency spectrum (42);
a ratio of physical quantities that can be deducted from said average frequency spectrum (42);
any parameter that is adapted to describe the shape of said average frequency spectrum.
