Acoustics

Acoustics is the branch of physics concerned with how sound is produced, travels, and interacts with spaces and materials.^[1] In audio production it governs everything from how a room colors a recording to how reflections, absorption, and resonance shape what a listener ultimately hears.

A practical understanding of acoustics informs choices about microphone placement, room treatment, and monitoring, because the space around a sound is as much a part of the result as the source itself. The same principles also guide how convincing virtual environments are built, since believable spaces must obey the way real sound behaves.^[2]
