How much energy is delivered to the eardrum

Reference no: EM13702644

Compute all parts of given problem:

Problem: Sound is detected when a sound wave causes the tympanic membrane (the eardrum) to vibrate. Typically, the diameter of this membrane is about 8.40mm in humans.

Part I: How much energy is delivered to the eardrum each second when someone whispers (20.3 dB) a secret in your ear?

E=______J

Part II: To comprehend how sensitive the ear is to very small amounts of energy, calculate how fast a typical 1.50mg mosquito would have to fly (in mm/s) to have this amount of kinetic energy.

I want you to explain the physics in this problem.
