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 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)
A source emits sound uniformly in all directions. A radial line is drawn from this source. On this line, determine the radial positions of two points, 1.04 m apart, such that the intensity level at one point is 2.87 dB greater than that at the other. (a) What is the smaller radial position (in m)? (b) What is the larger radial position (in m)? Sound sourcei B2 (a) Number Units (b) Number Units

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?
At 3meters from a source that is emitting sound uniformly in all directions the sound level is 53 db. What is the intensity of the sound at 3 meters
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%]
