Male Rana catesbeiana bullfrogs are known for their loud matingcall.The call is emitted not by the frog's mouth but by itseardrums, which lie on the surface of the head. And, surprisingly,the sound has nothing to do with the frog's inflated throat. If theemitted sound has a frequency
--------------µm
Can you get the intensity from the sound level? Do you know how totake an inverse log on your calculator? (It is probably marked as10x.) Did you use the reference intensity I0? Do you know how torelate the intensity to the wave amplitude? That will match theamplitude of the eardrum oscillations.
