Spectral pitch model corrections are segmented into adjustable level ranges

Evidence

The third function, g3, represents the difference between the masking pattern of the masking sound and the threshold in quiet at the critical-band rate of the test tone. It is most easily described by distinguishing three different level ranges as follows: for L1MTHQ < 15 dB or > 70 dB ; for 15dB :::; L1MTHQ :::; 60dB ; for 60 dB < L1MTHQ :::; 70 dB . — Professor Dr.-Ing.
