Thanks for that. But do you really mean a bandwidth of 48 kHz? I ask that
because I thought that the A-weighting curve is not defined for frequencies=

above 20 kHz and if it was defined, then the attenuation should be quite st=

at the (inaudible) ultrasonic frequencies above 20 kHz, wich should then le=
ad to
a significantly larger reduction than 2.7 or 3.7 dB. So, maybe you meant a=

sample rate of 48 kHz or a bandwidth of 22 kHz?
