Psychoacoustics measures detection, discrimination, magnitude, and recognition of sounds

Evidence

Measurements in this vein usually involve manipulating various stimulus parameters (like frequency and amplitude) and measuring the absolute threshold, the lowest stimulus level that evokes a sensation. … These experiments measure the just noticeable difference (JND), also known as the difference limen, defined as the amount a stimulus must be changed on a particular dimension before the change is detectable. … In these experiments, the loudness, the pitch, or the quality of sounds is measured. … Here, experiments adopt meaningful stimuli, and we measure the ability to identify musical instruments, words in speech, and even environmental sounds. — Jennifer Lentz, Psychoacoustics- Perception of Normal…, 58
