It has a peak amplitude of -56.7 dB. You really have to turn up the
volume to hear the peaks around 300 Hzi, 600 Hz and 10 KHz which
are around
-65 - -70 dB.
With some luck you should hear those very good in your headphones.
Yes I hear it very clearly, that's exactly the noise that was
bothering me :)
I checked with three headphones:
- a cheap philips : I hear absolutely nothing
- an AKG K240 : I hear it clearly now
- the sony MDR 7506: at least 2 or 3 times louder than the akg
Very interesting !
