- Suppose that a public address system emits sound uniformly in all directions and that there are no reflections. The intensity at a location 27 m away from the sound source is 3.0 X 10-4 W/m2. What is the intensity at a spot that is 80 m away?A sound wave traveling in 22 °C air has a sound intensity of 25 × 10-3 W/m2 Part (a) Assuming the density of air at this temperature is 1.19 kg/m3, what is the pressure variation of this sound wave in N/m2? Part (b) Calculate the sound intensity level in decibels.The sound intensity of a conversation at a distance of 5.0 m is 1.7 x 10-7 W / m^2 . Determine the intensity at a distance of 7.0 m. Presume the sound spreads evenly in all directions.
