Psychoacoustics quantifies physical sound signals into perceived auditory attributes

Evidence

The perceptual quality of sounds are considered auditory attributes: psychoacoustical research aims to find the quantitative relationships between the physical attributes of sounds and their perceived properties. … The physical attributes are evaluated by analyzing the sound signals, and the psychoacoustical research focuses on auditory attributes such as loudness, pitch, duration, and sharpness. — Almo Farina, Soundscape Ecology, 976

Psychoacoustics research aims to find the quantitative relationships between the physical attributes of sounds and their perceived properties and provides tools to measure the sensation that sounds produce in the listeners. The most common auditory attributes used in the psychoacoustic approach are loudness, pitch, duration, sharpness, roughness, fluctuation, and strength. — Almo Farina, Soundscape Ecology, 1160
