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 .
William M. Hartmann (born July 28, 1939) is a noted physicist, psychoacoustician, author, and former president of the Acoustical Society of America.His major contributions in psychoacoustics are in pitch perception, binaural hearing, and sound localization.
The relation of physical attributes of sound to perceived loudness consists of physical, physiological and psychological components. The study of apparent loudness is included in the topic of psychoacoustics and employs methods of psychophysics. In different industries, loudness may have different meanings and different measurement standards.
The equivalent rectangular bandwidth or ERB is a measure used in psychoacoustics, which gives an approximation to the bandwidths of the filters in human hearing, using the unrealistic but convenient simplification of modeling the filters as rectangular band-pass filters, or band-stop filters, like in tailor-made notched music training (TMNMT).

In a deeper biological look at the phenomenon of psychoacoustics, it was discovered that the central nervous system is activated by basic acoustical characteristics of music. [33] By observing how the central nervous system, which includes the brain and spine, is influenced by acoustics, the pathway in which acoustic affects the mind, and ...
Harold Burris-Meyer (1902-September 27, 1984) [3] was a twentieth century American scientist who investigated the use of sound as a tool for emotional and physiological control and played a critical role in the emerging fields of sound design for theater, productivity music for industry, and applied psychoacoustics for warfare.

The concept of backward masking originated in psychoacoustics, referring to temporal masking of quiet sounds that occur moments before a louder sound.. In cognitive psychology, visual backward masking involves presenting one visual stimulus (a "mask" or "masking stimulus") immediately after a brief (usually 30 ms) "target" visual stimulus resulting in a failure to consciously perceive the ...
