Homework Help: Sound energy passing through a hole

  1. Jun 12, 2014 #1
    1. The problem statement, all variables and given/known data
    "A continous sound wave with a sound intensity level of 80dB passes through a hole in a wall which has a cross-sectional area of 3m^2. How much energy passes through this hole in 10 minutes, in joules?"

    If anyone can show me how this problem is solved it's be much appreciated. Thanks

    2. Relevant equations

    dB = 10log10 (I/Io)

    3. The attempt at a solution

    Suppose instead of units of dB you had Joules per square meter per second (a.k.a. Watts per square meter a.k.a. Intensity)

    Then how would you solve the problem?
