How long could sound travel before losing energy?
Posted on 31 January 2009 by admin
Sound travels at 1100 feet per second. What distance could it conceivably travel before it finally loses it energy? Is it dependent on how much energy is produced in conjunction with that sound?
It will be subject to dampening on a continuous basis. Sound waves are dampened according to an inverse square law, where sound level drops as function of the square of the distance traveled.
Amount of dampening depends on the medium it is traveling through.
The dampening will continue until all energy is dissipated – long after you can still hear it. So, the sound will still propagate, or move, through the medium long after you are unable to hear it.
The length of time you will still be able to hear the sound will depend on how much energy the original sound had, and the medium it traveling in.
