The Sound From A Trumpet Radiates Uniformly In All Directions In Air With A Temperature Of 20 C At A Distance Of 5 07 2 (98.01 KiB) Viewed 40 times
The sound from a trumpet radiates uniformly in all directions in air with a temperature of 20° C. At a distance of 5.07 m from the trumpet the sound intensity level is 53.0 dB. The frequency is 581 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. 2 What is the pressure amplitude at this distance?
