Imagine that you have three boxes, one containing two black marbles, one containing two white marbles, and the third, one black marble and one white marble. The boxes were labeled for their contents – BB, WW and BW – but someone has switched the labels so that . 5.1.9. You and I are standing next to each other, listening to the exact same steady sound. . Our ears are identical. . You listen for TWICE as long as I do. How does the (average) power compare? (Please average ONLY over the time that the individual is listening!). 5.1.9.

PROGRAM. 1. 28 Jan 2013. Learning Objectives. Explain the parameters of sound and how they are measured. Apply the parameters of sound to the sensitivity of the human ear. Apply the parameters of speech and sound to an audiogram. Sound waves carry energy that can be used to do work, like forcing the eardrum to vibrate.. The energy can be great enough to cause damage to windows and buildings (sonic boom). Sound Intensity. The amount of energy transported per second by a sound wave is the . PROGRAM. 1. 28 Jan 2013.
