A sound wave with intensity 2 × 10-3 W / m^2 is considered as moderately loud to our ears. The drum inside our ear has a diameter of 6 mm. Show that the energy transferred to the drum of our ear if you hear the above sound wave for 60 seconds is E = 3.4 × 10-6 J. Consider the drum as a round surface.

Sound is detected when a sound wave causes the tympanic membrane (the eardrum) to vibrate (see the figure (Figure 1)). Typically, the diameter of this membrane is about 8.40 mm in humans. a)How much energy is delivered to the eardrum each second when someone whispers (19.5 dB ) a secret in your ear? (in Joule) b)To comprehend how sensitive the ear is to very small amounts of energy, calculate how fast a typical 2.50 mg mosquito would have to fly...
