Sound Question

  1. Jan 18, 2007 #1
    1. The problem statement, all variables and given/known data
    A baby's mouth is a distance of 35.0 cm from her father's ear and a distance of 1.52 m from her mother's ear.

    Child Sounds <------------0.35m-------->Father
    X <----------------------------1.52m-----------------> Mother


    2. Relevant equations
    I(Father) = p / 4pi(d^2)
    I(Mother) = p/ 4pi(d^2)

    B1 = 10 log(I1/I_o)
    B2 = 10 log(I2/I_o)

    B2 - B1

    3. The attempt at a solution

    Sorry, the question is:

    What is the difference between the sound intensity levels heard by the father and by the mother?

    Does anyone know how to start this problem?
