In Reply to: Amp wattage question posted by Valnar on June 10, 2004 at 13:32:56:
A 3db increase is twice the power, but not twice as loud. The ear is non-linear. Physiologists have devised a scale of loudness, which rank-orders sound from soft to loud on units of sones. The physical quantity measured is the sound pressure level. One thousand Hz is used as a reference frequency (where the ear is most sensitive), at a sound pressure level of 40 db above the threshold of hearing (0.0002 microbar). This level is refered to as 1 sone. Doubling the loudness is equal to 2 sones. The result was that for the ear to percieve a doubling in loudness, it takes a 10db change in sound pressure. So, it would take 10 times the amplifier power to be percieved as twice as loud, assuming the loudspeakers could handle to increase of 10db. So, you are right. doubling your power from 100 to 200 watts wont make much of a diffference. Long live horn loudspeakers!!
