A gunshot consists of a logarithmic intensity (loudness) of 150 dB. The frequencies contained in the sound of the blast don’t have the resonance frequencies for the ear canal. Suppose that the tympanic membrane (ear drum) consists of an area of 1 cm2, and the oval window consists of an area 25 times smaller. As well suppose that the ossicles amplify by a factor of 2X.
i) What force is applied by the stirrup on the oval window?
ii) Determine the amplitude of the pressure wave entering to the cochlea?
iii) Determine the intensity of the pressure wave entering into the cochlea? Suppose that the fluid filling the cochlea is similar to water.
