A sound wave traveling in 20°C air has a pressure amplitude of 0.800 Pa. What is the intensity of the wave? (Assume the density of air is 1.29 kg/m3. Enter your answer in W/m2.)
Taking the threshold of hearing to be 1.00 x 10-12 w/m², determine the level of sound (in
decibels) that can be produced from a sound wave with an intensity of 3.00 µW/m².
The amplitude of a sound wave is measured in terms of its maximum gauge pressure. By what factor does the amplitude of a sound wave increase if the sound level goes up by 36.0 dB?
