Question

The eardrum is displaced surprisingly little when a sound wave strikes it. Some idea of the displacement of the eardrum by a sound wave can be obtained by using Equation 7.1: The displacement amplitude, A, of the air molecules gives us a lower limit to the displacement of the eardrum. At the threshold of hearing at 3.7 kHz, the sound intensity is about. The threshold of pain begins at an intensity of [19]. What is the amplitude of eardrum vibrations at these intensities? The density of air is [19] F. R. Hallett, P. A. Speight, R. H. Stinson, INTRODUCTORY BIOPHYSICS, (New York: John Wiley & Sons, 1977). (at threshold of hearing) (This value is ~ 3/100 the diameter of a hydrogen atom!)

Explanation / Answer

The equation is:
Sound intensity I = ?
