Psychoacoustics. Psychoacoustics is the branch of psychophysics involving the scientific study of the perception of sound by the human auditory system. It is the branch of science studying the psychological responses associated with sound including noise, speech, and music. Psychoacoustics is an interdisciplinary field including psychology ...
Precedence effect. The precedence effect or law of the first wavefront is a binaural psychoacoustical effect concerning sound reflection and the perception of echoes. When two versions of the same sound presented are separated by a sufficiently short time delay (below the listener's echo threshold), listeners perceive a single auditory event ...
Critical band. In audiology and psychoacoustics the concept of critical bands, introduced by Harvey Fletcher in 1933 [ 1] and refined in 1940, [ 2] describes the frequency bandwidth of the "auditory filter" created by the cochlea, the sense organ of hearing within the inner ear. Roughly, the critical band is the band of audio frequencies within ...
Just-noticeable difference. In the branch of experimental psychology focused on sense, sensation, and perception, which is called psychophysics, a just-noticeable difference or JND is the amount something must be changed in order for a difference to be noticeable, detectable at least half the time.

Maryanne Amacher (February 25, 1938 – October 22, 2009) was an American composer and installation artist. She is known for working extensively with a family of psychoacoustic phenomena called auditory distortion products (also known as distortion product otoacoustic emissions and combination tones), in which the ears themselves produce audible sound.
Sound is a signal that is analysed by the ear; to understand this process, we need foundations of signal processing. To understand auditory perception, we perform psychoacoustic experiments, which are generally about relationships between and among Popper's three worlds.
The next image represents a simple block diagram of the relationship between the human audio system and an objective psychoacoustic model. thumbs. From the model comparison of the test signal with the (original) reference signal, a number of model output variables are derived. Each model output variable may measure different psychoacoustic ...
