Thanks for the replys. What I meant to say was I thought the question gave you sound intensity and you have to use the sound intensity = 10log(Icurrent/Ithreshold) equation to find the intensity, and then find the power and energy from that. I believe you are right, but could you tell me why you...
Here's a question I got on an exam:
During a typical workday (eight hours), the average sound intensity arriving at Larry's ear is 1.8 x 10-5 W/m2. If the area of Larry's ear through which the sound passes is 2.1 10-3 m2, what is the total energy entering each of Larry's ears during the...
