Homework Help: Factors affecting sound intensity

  1. Aug 2, 2014 #1
    1. The problem statement, all variables and given/known data
    the factor affecting sound intensity is amplitude and frequency . why not also the distance from the source (r) ,

    in my opinion, intensity = power/area , so the intensity = power/ 4 pi r ^2 .... so I is inversely proportional to r^2 ...

    2. Relevant equations

    3. The attempt at a solution

    I think you should take another look at the definition of intensity and compare it to the definition of power.
