Description of the audioprocessor
4.2
4.2.1
Loudness
There are four parameters programmable in the loudness stage.
Loudness attenuation
Figure 4 shows the attenuation as a function of frequency at f_P = 400 Hz.
Figure 4. Loudness attenuation @ f_P = 400 Hz.
4.2.2
Peak frequency
Figure 5 shows the four possible peak-frequencies at 400, 800 and 2400 Hz.
Figure 5. Loudness center frequencies @ attn. = 15 dB.
