Question and answer
By what amount (in dB) does the intensity level decrease when you increase your distance from a source by a factor of 3?
Sound intensity level decreases inversely as the square of the distance. the intensity of the sound wave decreases with increasing distance from the source. [ So if the distance from the source is doubled (increased by a factor of 2), then the intensity is quartered (decreased by a factor of 4). Similarly, if the distance from the source is quadrupled, then the intensity is decreased by a factor
of 16. ]
