A point source of sound emits a constant power with intensity inversely proportinal to the square of the distance from the source . By how many decible does the sound intensity level drops when you move from point `P_(1)` to `P_(2)` ? Distance of `P_(2)` from the source is two times the distance of source from `P_(1)` .
