The sound from a trumpet radiates uniformly in all directions in air with a temperature of 20∘C. At a distance of 4.98 m from the trumpet the sound intensity level is 56.0 dB. The frequency is 586 Hz. Use 344 m/s for the speed of sound in air, 1.20 kg/m3 for the density of air, and 1.00×10−12 W/m2 for the reference intensity. a) What is the pressure amplitude at this distance? b) What is the displacement amplitude?

DUE Monday, March 19 [15 marks] 1. [5] The measured speed of sound in fresh water (density 1000 kg/m3) at various temperatures is shown in the graph below. (a) Use this graph to generate a similar graph showing how the bulk modulus varies with temperature. For simplicity, consider only every other point and assume that the density of water remains constant. (b) In reality, the density of water decreases slightly with increasing temperature, with water reaching a maximum density of...

Q6. (1) Using the measured speed of sound from longer pipe, estimate the temperature of the lab room, with uncertainty. The speed of sound is given by v 331 +0.6T (m/s), where T is the temperature in degrees Celsius. Does this find the lab room to be significantly warmer or colder than room temperature (say, 20+20C)? Justify using your uncertainties. Also, does this result make sense? Does...

The speed of sound in air (in m/s) depends on the temperature according to the approximate expression below, where TC is the Celsius temperature. In dry air the temperature decreases about 1°C for every 150 m rise in altitude. v = 331.5 + 0.607TC (a) Assuming this change is constant up to an altitude of 9000 m, how long will it take the sound from an airplane at 8800 m to reach the ground on a day when the ground...
