Description

technical field

[0001] The invention relates to the technical field of acoustic wave monitoring, and more particularly relates to an acoustic wave monitoring device and method combined with psychoacoustic evaluation. Background technique

[0002] Psychoacoustics is a subject that studies people's perception of sound, that is, the science that studies people's physiological and psychological responses to sound, and is a branch of psychophysics. The research on psychoacoustics started very early in foreign countries, and most of the existing basic theories, calculation models and standards are the results of foreign research. The Technical University of Munich in Germany established a calculation model of psychoacoustic parameters through a large number of experimental data, and successfully established a psychoacoustic system. The School of Experimental Psychology at the University of Cambridge has made great achievements in the field of psychoacoustics. The Department of A...
