As you learned in class, a sound wave is a pressure wave that propagates through the air (or other medium). This means that at some points the pressure isincreased (beyond normal) and at others the pressure is decreased (beyond normal). While increases in pressure can be arbitrarily large, the pressure canonly be decreased to 0 Pa. Beyond this the sound wave will be "clipped" and the sound wave will be distorted. The amplitude of the pressure distortion AP isrelated to the Intensity of the sound I by the relation I-AP²/(2pu) where p is the density of air (1.29 kg/m³) and is the speed of sound 340.5 m/s. Find themaximum sound level of a sound that can propagate undistorted through the air if the outside pressure is 101.7 kPa.Number Your friend is firing a gun, and you want to be a safe distance away, so you walk away until there is 1.9 s between the time you see the gun fire, and the timeyou hear it. You think this still might not be safe enough, so you back up more until the loudness decreases by 6.05 dB. How long does it take the soundfrom the gunshot to reach you now?NumberHint, you may find it useful to remember that logA-logB=log(A/B), and use the speed of sound as 340 m/s.S.
