One the ear hears on a logarithmic scale, and second what the perceived loudness appears to be is dependant on the distance from the sound source, which is not particularly pertinent in this query. Hence a 100 watt Marshall amp does not sound twice as loud as a 50 watt amp, assuming same type of amp at the same distance. What sounds twice as loud at 3 metres would not sound twice as loud at 6 metres (approximations used.) It was always taken that you required a 3dB increase for the human ear to notice any increase in loudness. Just my musing, but thought maybe of interest. -- Geoff ----------------------------------------------------------------- To stop getting this list send a message containing just the word "unsubscribe" to [EMAIL PROTECTED]
