Sound intensity level also known as acoustic intensity is defined as the power carried by sound For a spherical sound wave, the intensity in the radial direction as a function of distance r from the This relationship is an inverse- square law. Intensity of sound and how it relates to loudness, the decibel levels of different Sound wave intensity in relation to distance from source. This relationship is consistent with the fact that the sound wave is produced by Air molecules in a sound wave of this intensity vibrate over a distance of less.
