Jenny and her friend Elaine are attending a rock concert. Elaine had 20-point special tickets to the VIP area and is standing 10 m from the stage. Using her portable equipment, she determines that the noise in her section is 100 decibels. Jenny had cheaper tickets and is standing 100 m away.
a) Using the inverse square law, how does the sound intensity compare where Jenny is (100 m from the stage) compared to where Elaine is (10 m from the stage)?
b) How loud is it where Jenny is standing (in dB)?
