If the sound intensity of sound produced from a source at a distance (d) meter from a person = (1) watt/m^2, so the sound intensity at a distance (1/2 d) = ........1
A. 1/4 B. 1/2 C.1 D.4

Answer:

How does the intensity of a sound wave change if the distance from the source is reduced by a factor of three?

As a sound wave carries its energy through a two-dimensional or three-dimensional medium, the intensity of the sound wave decreases with increasing distance from the source. ... The intensity varies inversely with the square of the distance from the source.
