Webassign night again!! 1. The problem statement, all variables and given/known data During normal conversation, the amplitude of a pressure wave is 0.023 Pa. (a) If the area of the eardrum is 0.56 cm2, what is the force on the eardrum? N (b) The mechanical advantage of the three bones in the middle ear is 1.5. If the force in part a is transmitted undiminished to the bones, what force do the bones exert on the oval window, the membrane to which the third bone is attached? N (c) The area of the oval window is 0.026 cm2. What is the pressure increase transmitted to the liquid in the cochlea? Pa 2. Relevant equations I'd assume I'd be using dB=20log(P/P) But I'm not sure how to apply that to any of these equations. 3. The attempt at a solution Can't even figure out where to start. I'm sure with some starting advice, or at least how to solve the first part I could figure it out.
