Scientific Essence Of Sound: Understanding Sound Propagation

Pro Sound Web: Let’s have a look at sound particles, acoustic pressure, propagation medium density, particle velocity, acoustic energy, volume velocity, and acoustic impedance.
Abstract concepts? Nope—far from it. All are related to the physics of sound propagation in an elastic medium that result in changes to the displacement, pressure, density, temperature, and velocity within the medium.

This article provided a good technical overview of the physical properties of sound waves. It is a good starting point for understanding the higher level concepts of audio, which are not required for basic operation and knowledge of sound systems. Understanding how sound propagates is necessary to effectively design sound systems for all applications. Knowledge of where to place loudspeakers can only be helped by understanding how sound will propagate from a specific location.
