I mean whatever comes out of he speaker that commonly gets
measured in terms of dB - say a mfr will claim that his
speaker will "put out" 120 dB I guess right at the front
plane of the speaker enclosure.
So, I would need to know for this case what amplifier power
would be required to drive a speaker at 120 dB vs. at 110 or 100 dB.
Bottom line is that I am trying to add an environmentalism
aspect to my claim that extremely loud, outdoor, band music
not only contributes to sound pollution for a neighborhood,
but it also wastes a lot more electrical energy than one might expect.
power requirement increased?
Hi Jeff,
Long shot here, but since you are looking a bit into audio:
If one increases by 10 dB the sound level out of a speaker at a
specified distance, by what factor has the amplifier
