Technology / Home Audio / Inverse Square Law: In mathematics, the law that states that in the absence of reflective surfaces, sound pressure (or light) falls off at a rate inverse to the square of the distance from its source. In other words, every time the distance from the sound source is doubled, the sound pressure level is reduced by a factor of 4, or 12 db.
