Calculate the relative sound intensity of a wave after passing through 5 cm of muscle and 2 cm of bone, as a percent of the initial intensity. (note attenuation coefficient is 1-3.3 for muscle and 15 for bone) it doesnt say but i think we are supposed to use beers law I=Ioe-ax a is attenuation coefficient and x is distance. problem im having is the value i am getting is super small and incorrect

A woman stands a distance d from a loud motor that emits sound uniformly in all directions. The sound intensity at her position is an uncomfortable 3.2 *10-3 W/m2. At a position twice as far from the motor, calculate the following: (a) the sound intensity in W/m2 (b) the sound intensity level relative to the threshold of hearing
