Problem 60P

CP The sound from a trumpet radiates uniformly in all directions in 20o C air. At a distance of 5.00 m from the trumpet the sound intensity level is 52.0 dB. The frequency is 587 Hz. (a) What is the pressure amplitude at this distance? (b) What is the displacement amplitude? (c) At what distance is the sound intensity level 30.0 dB?

Step-by-Step Solution:

Solution 60P Problem (a) Step 1: Pressure amplitude v = 344 m/s = 1.2 kg/m3 = 52dB I = 10 1W/m 2 0 f = 587 Hz
