A spherical source of sound radiates uniformly into a large volume of air at 228C (295.2K or 728F) and 101.3 kPa (14.7 psia). The frequency of the sound wave is 274 Hz, and the acoustic power radiated from the source is 30 mW. At a radial distance of 500 mm (41.7 in) from the source, determine the intensity, the rms acoustic pressure, the rms acoustic particle velocity, and the acoustic energy density.
