Quizplus · Accepted Answer

According to the inverse square law, the intensity of sound decreases by 1/4 (or 0.25) for every doubling of the distance between the sound source and the listener. Therefore, quadrupling the distance will result in a decrease of (0.25)^2 or 1/16 in intensity. So, the answer is A) 1/16.
