The point source is the sound source that propagates from one point to all directions. This kind of sound source forms a toroidal wave. The wavefront area is proportional to the square of the distance. Therefore, the sound intensity is attenuated according to the square of the distance, that is, the distance is doubled. The sound level of aging is reduced by 6 decibels.
