Inverse Square Law

  1. Oct 14, 2004 #1
    I had a question regarding a sound with a given Intensity and a given radius (say 0.1m from point source) for that intensity that travels through a door with dimensions given as well. It was gives a second radius (say 30m from point source) asking what the acoustic power was at a second radius after travelling through the door.

    I know I am using the inverse square law to relate the second intensity, but how do I figure the door into the question?

    Im sorry I cant give the exact question, it was in a quiz and I dont have any similar examples with me. Im trying to remember the question off the top of my head.

    Any help would be excellent.
