5.4 Loudness
There are four parameters programmable in the loudness stage:
5.4.1 Attenuation
Figure 6 shows the attenuation as a function of frequency at fP = 400Hz.
Figure 6. Loudness Attenuation @ fP = 400Hz
5.4.2 Peak Frequency
Figure 7 shows the four possible peak-frequencies at 200, 400, 600 and 800Hz
