AB  - The usual assumption that air provides a linear medium for sound propagation is not valid at high intensities. An analytic procedure and experimental measurements show that when two harmonic waves propagate, an intermodulation phenomenon appears because nonlinear acoustic phenomena occur in fluid media. Regardless of the quality of the loudspeaker, high-fidelity sound reproduction is theoretically impossible with high particle velocity.
