Psychoacoustics is a branch of psychophysics that studies the subjective perception of sound. It explores how humans interpret and experience acoustic phenomena, moving beyond the purely physical properties of sound waves. This field investigates the relationship between the objective, measurable aspects of sound, such as frequency, amplitude, and waveform, and the subjective, perceptual responses, such as loudness, pitch, timbre, and spatial location.

Key areas within psychoacoustics include the study of auditory thresholds, the minimum intensity at which a sound can be detected, and the just-noticeable difference, the smallest change in a sound's property that can be perceived. It also examines how the ear and brain process complex sounds, including the mechanisms of masking, where one sound makes another harder to hear, and the perception of consonance and dissonance in musical intervals.

Psychoacoustic principles have practical applications in various fields. In audio engineering and music production, they inform decisions about audio compression, equalization, and the design of listening environments to optimize the perceived sound quality. In acoustics, psychoacoustics helps understand the impact of noise on people, leading to better noise control strategies. Furthermore, it contributes to the development of hearing aids and other assistive listening devices, aiming to improve the auditory experience for individuals with hearing impairments. Researchers in psychoacoustics often use controlled listening experiments to gather data on subjective responses to specific acoustic stimuli.
