A patient is having a process termed as extracorporeal shock wave lithotripsy (ESWL) done. This process employs sound waves to disrupt kidney stones. Suppose that the sound enters one side of the body from water in the direction perpendicular to the body’s surface. The sound waves then enter the kidney perpendicularly as well. Suppose that the cross sectional area of the kidney is 50 cm2. The density of tissue among the surface of body and the kidney is 0.950 g/cm3, and the speed of sound in this tissue is 1.440 X 105 cm/s. The density of kidney is 1.04 g/cm3, and the speed of sound in the kidney is 1.557 X 105 cm/s. 150 J of energy is to be passed via the kidney. What total time must the sound waves is permitted to pass through the kidney when the logarithmic intensity of the wave is around 150 dB?
