Question
A large glass window, 50 mm (1.97 in) thick, is placed in the dolphin tank at Sea World. Seawater (Zo = 1.533 × 106 rayl) is on one side of the window and atmospheric air (Zo = 415 rayl) is on the other side. A plane sound wave in the air strikes the window at normal incidence. The frequency of the sound wave is 2 kHz. The resulting sound pressure level transmitted into the seawater is 114.3 dB. Determine [A] the acoustic intensity of the incident wave and [B] the rms acoustic pressure of the incident wave.
