![The sound emitted by a point sounds quieter the further away you are, obviously. This is because the energy is being spread over a larger area at bigger distances. The above animation shows a good visualisation of this process- the area of the sphere over which the energy is distributed grows quickly. In fact, the area is proportional to the distance squared. This is one way to justify why light, sound and even gravity follow inverse-square laws, (where the intensity is proportional to 1 over the distance squared).
