Question

A small spherical sound source is radiating 1 watt of single frequency
(1000HZ) sound power into free space. Calculate the following at a
distance of 0.3m.

(e) mean active sound intensity
(f) reactive sound intensity amplitude
(g) sound intensity level
(h) If the source also radiated 1 watt of acoustic power at 1500HZ
simultaneously with the 1000HZ signal, what would be the total
r.m.s. sound pressure?
