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? Use 1.42×105 Pa...

The frequency is 584 Hz . Part A What is the pressure amplitude at this distance? 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. Part B What is the displacement...
A sound wave radiates from a source in all directions. If the power of the sound source is 200 watts, then the intensity level of the sound wave 1000 m from the source is (in dB)
Q2. A siren radiates sound uniformly in all directions. A person standing a distance L from the siren regsiters a sound intensity level of 115 dB but a person standing twice that distance registers an intensity of 109 dB. What is the ratio of the intensities at those points. What will the sound intensity level at a distance of 12 L be?
