For this report, we will assume a **standard **temperature of 20 degrees Celsius, and a corresponding speed of sound of 343 m s (Canadian Center). A sound speed of 343 m s means a pressure change maximum will move 343 meters in the direction of propagation in one second. The amplitude of a sound wave is directly proportional to the loudness of the ...
