Amp "A" - 250W, Amp "B" - 40W
a) Estimate sound level in dB you would expect at a point of 3.5m from a speaker connected to each amplifier.


I think the formula to start with is to convert watts to decibels(B). B = 10xlog (I/1x10-12)

okay the superscript isn't working....that's I divided by 1 x 10 to the power of negative 12.

I = the watt of each speaker.... for some reason though I cannot figure out from there....

aside from not knowing how to use my calculator properly for these types of equations.

Please help!
