A certain loudspeaker system emits sound isotropically with a frequency of 2270 Hz and an intensity of 1.05 mW/m2 at a distance of 5.26 m. Assume that there are no reflections. (a) What is the intensity (in mW/m^2) at 26.0 m? At 5.26 m, what are (b) the displacement amplitude and (c) the pressure amplitude of the sound? Take the speed of sound to be 343 m/s and the density of air to be 1.21 kg/m3.
