psychoacoustics
Sound perception research
Psychoacoustics is the study of how humans perceive sound—the relationship between physical acoustic properties and psychological responses to them.
The field examines how the brain processes pitch, loudness, timbre, and spatial location.
Psychoacoustic principles inform audio engineering, hearing aid design, and music production: MP3 compression relies on psychoacoustic research to remove frequencies humans can't easily perceive.
