We will assume that a sound wave, once generated and emitted, will propagate uniformly in all directions of 3-dimensional space. Find an expression for the displacement s(r, t) of the air particles from equilibrium, where r is the radial distance from the source, and t is time. Introduce physical constants/coefficients, with appropriate physical dimensions, when necessary.
