1. The problem statement, all variables and given/known data A fan at a rock concert is 30 from the edge of the stage. The sound intensity level at the edge of the stage is 110 dB. The fan's eardrums have a diameter of 8.4 . How much energy is transferred to each eardrum in one second? (Hint: It may help to asume that the speaker is on the stage located 1.0 m from the edge.) Answer should be expressed in Joules. 2. Relevant equations I=P/4πr^2, β=(10dB)log(I/Iinitial) 3. The attempt at a solution ? Thanks for your help!
