A sound wave from a siren has an intensity of 106.1 W/m2 at a certain point, and a second sound wave from a nearby ambulance has an intensity level 11 dB greater than the siren's sound wave at the same point. What is the intensity level of the sound wave due to the ambulance? Answer in dB
A sound wave from a siren has an intensity of 106.4 W/m2 at a certain point, and a second sound wave from a nearby ambulance has an intensity level 9 dB greater than the siren's sound wave at the same point. What is the intensity level of the sound wave due to the ambulance? dB
At a distance of 5.02 m from a siren, the sound intensity is 3.48 × 10-2 W/m2. Assuming that the siren radiates sound uniformly in all directions, find the total power radiated.
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?
21-3 Sound Intensity Mar 30 at 11:59 Level Due this Frida pm (EDT) At a distance of 4.75 m from a localized sound source, you measure the intensity level as 73.0 dB.

A sound source in all directions with the same intensity. If at point A, which is 3.00 m from the source, the sound intensity level is 80.0 dB. At what distance from the source is point B, if the intensity level of the sound in it is 60.0 dB? determine the distance from the source to point B
2) (8 points) Show your work for full credit. An omnidirectional loudspeaker produces sound waves uniformly in all directions. A sound intensity of 100 W/mºis measured 1.0 m from the speaker. (a) How far from the speaker will the sound intensity be measured to be 1.0 W/mº? (b) At what distance from the speaker will the sound intensity level be 100.0 dB?
A city police siren radiates sound intensity of 3.34W/m2 which can be heard at an exact distance of 498 m away. At what sound intensity level can it be heard 69.5 m away from the siren? Answer:
