(a) If the sound level is attenuated by -40 dB between the bar and your eardrum, and the sound level is 60 dB at your eardrum, what are the amplitudes of the sound waves at the surface of the bar and at your eardrum?
(b) What are the gauge pressure amplitudes corresponding to the displacement amplitudes you found in part (a)?
