A point source of sound generates a 200 Hz tone. The wave has an intensity of 2.2×10−8 W/m2 at a distance of 3 m from the source. Find the total sound power at the source. At what distance from the source is the decibel level below 15 dB? What is the intensity of the sound at this distance?
4 A point sound source emits a sinusoidal wave at a frequency of 2,000 Hz. The pOwer of the sound at the source is 10 watt. What are: the sound intensity, the sound intensity level and the loudness of that sound at (a) a distance of Im from the source? (b) at a distance of 2m from the source?
Sound waves at ultrasonic frequencies attenuate much faster than audible sound waves. The sound intensity level of a point source of ultrasonic sound waves is measured as 100 dB at a distance of 1.00 m from the source and 65 dB at 2.00 m. Assuming the waves spread in all directions, what is the attenuation coefficient alpha? [Answer in 1/m to within 5%]

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)
By measurement you determine that sound waves are spreading out equally in all directions from a point source and that the intensity is 2.9 times 10^-2 W/m^2 at a distance of 4.7 m from the source. What is the intensity at a distance of 3.0 m from the source? Express your answer using two significant figures. How much sound energy does the source emit in one hour if its power output remains constant? Express your answer using two significant figures.
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
