Homework Statement


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


Homework 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
