Thanks very much for the information guys! very useful :) on a final note, in which way must things be 100% efficient?

What if the sound is produced virtually? computer-generated and put through a speaker big enough to artificially create the sound power of 180db? would that be using more power output? To my mind, to do it the way I just put it wouldn't need a million watts or more to generate the sound...

Hi Guys, I know that sound power can be measured in watts. For example a Jackhammer is around 120db which would produce a watt of electricity. My question is, if I wished to artificially create a sound at the same db would you have to put in as much energy? For example... if a rocket...

Yes, you have! perfectly. Thank you very much :)

Hi guys, quick query (at least I think it's quick!). I know that, in a microphone, when a waveform passes through the electromagnetic field it resonates the diaphragm and in turn moves the induction coil set in the middle, creating a VARYING current... My question is: Is the varying...
