If the intensity of a sound wave is 10 W/m² at a distance of 5 m from the source, calculate the intensity at a distance of 20 m from the source.

The intensity of the sound wave from an airplane is 1.0 × 102 W/m2 at 5.0 m. What is the intensity at 100 m?

The sound of a band is rated as 60 dB at a distance of 10.0 m. What is the sound intensity level of the band when one is 20.0 m from the band?

A microphone records sound produced from two speakers. As the microphone is moved around, a position at which the microphone receives a minimum intensity is found. If the intensity of one of the sound waves alone at that location is 0.055 W/m2, and if the microphone receives an intensity of 0.004 W/m2 there, what is a possible value for the intensity of the other source at the microphone’s location?

A sound source of power 100 watts radiates sound uniformly in all directions. The intensity of the sound at a distance of 4.00 m is

The sound intensity at a person’s seat in a concert hall is 8.010–5 W m–2. Calculate thesound intensity level, in decibels, at the seat. (Use 1.010–12 W m–2 as the reference level.)
