Acoustics, the study of sound, is a topic that can quickly mystify the casual observer. Fundamentally, it is the physics of how air molecules as a population behave when excited by moving objects. The mathematics used to describe this behavior can be complicated, especially as mathematics isn’t our native language. Nonetheless, the behavior itself is conceptually simple enough – as anyone who has tossed pebbles into a pond knows. A rock striking the water’s surface causes ripples to spread out in all directions until they bounce off the edges of the pond and reflect back ...
