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?
A spherical source radiates sound uniformly in all directions. At a distance of 14 m, the sound intensity level is 90 dB. What power is radiated by this source?
A spherical source radiates sound uniformly in all directions. At a distance of 9 m, the sound intensity level is 100 dB. What power is radiated by this source?
A siren at a distance of 30. m produces a sound intensity of 1.0x10^-2 W/m^2. What sound level is expected from this siren at that location? A siren at a distance of 30. m produces a sound intensity of 1.0x10^-2 W/m^2. What sound level is expected from this siren at that location? 1.0x10^-1 dB 1.0 db 1.0x10^-2 dB 1.0x10^2 dB 1.0x10^1 dB
The mean distance between the Earth and the Sun is 1.50×1011 m. The average intensity of solar radiation incident on the upper atmosphere of the Earth is 1390 W/m2. Assuming that the Sun emits radiation uniformly in all directions, determine the total power radiated by the Sun.
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:

A woman stands a distance d from a loud motor that emits sound uniformly in all directions. The sound intensity at her position is an uncomfortable 3.2 *10-3 W/m2. At a position twice as far from the motor, calculate the following: (a) the sound intensity in W/m2 (b) the sound intensity level relative to the threshold of hearing
