Sound decays exponentially as a function of distance, so speakers close to you don't need to be loud. Also most speakers are also fairly directional, so i'd expect any extra energy to be absorbed by the room (as heat).
Edit: more importantly these are destructive waves, so if anything you’d actually reduce reflections back out into the world.
- Robotbeat 6y agoNot exactly exponentially.
- vages 6y agoYes, it's not exponential. The sound level is inversely proportional to the square of the distance.
- gmantg 6y agoThis is 1/d^2. Exponential would be 1/2^d.
- anticensor 6y agoIt is actually between the two because sound is a material wave and air has friction.

- ed 6y agoah yeah, thanks!
