When moving six times farther away from a constant sound power source, the decibel value of the sound intensity level drops by 15.6 dB. Sound intensity decreases as the square of the distance from the source, so moving six times farther results in a drop of 15.6 dB according to the inverse square law for sound intensity and decibel calculations.
