What do you need and how to calculate a distance traveled by sound? For example if you hit a bell with a specific amount of power how far will it travel?

    $\begingroup$ There won't be a definitive point where the wave will "stop". The wave's intensity would exponentially die down with distance, and it greatly depends on the conditions of the medium it is travelling through. $\endgroup$ – udiboy1209 Jan 21 '14 at 19:28
  • $\begingroup$ Like udiboy said, it'll travel to infinity if there's a sound-carrying medium that far. $\endgroup$ – Carl Witthoft Jan 21 '14 at 20:07
  • $\begingroup$ Surely there is a distance at which it becomes undetectable, even though that might depend on the size of any detection apparatus? $\endgroup$ – Keith Jan 22 '14 at 5:42
