Asuming the attenuator is calculated using sound pressure or voltage, 
-40 dB is 100 times less powerful (though probably circa 8 times   
less loud in times of how loud you actually perceive it). Really you 
want it as loud as it can be without distortion, even though you can
amplify it afterwards. I would try -10 dB first (should sound about 
half as loud).
