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 engine at 180db produced a potential of a million watts, if I wanted to artificially create this decibal volume would a million watts of energy have to be put in to it to generate it? Thanks guys!
