Acoustic monitoring device and method combining psychological acoustic evaluation

Abstract

The invention discloses an acoustic monitoring device and method combining psychological acoustic evaluation. The acoustic monitoring device comprises an acoustic signal acquisition module, an acoustic signal processing module and a psychological acoustic evaluation module, wherein the acoustic signal acquisition module is used for acquiring audio signals and transmitting the audio signals to the audio signal processing module; the acoustic signal processing module is used for filtering the audio signals and transmitting the audio signals to the psychological acoustic evaluation module; the psychological acoustic evaluation module is used for obtaining quality information of the audio signals through psychological acoustic analysis. The acoustic monitoring device and method can be used for conveniently and efficiently acquiring acoustic wave in the living environment, carrying out psychological acoustic evaluation on the acoustic wave and finally generating valuable evaluation information and suggestions.

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...

Problems solved by technology

However, some studies at home and abroad remain at the theoretical level, and some are aimed at specific issues such as automobiles. None of them have conducted detailed research on the direction of ultrasonic and infrasonic perception speed measurement. Ultrasonic and infrasonic waves seriously affect people's perception in daily life. Living environment and physical and mental health, so there is an urgent need for a device that can apply psychoacoustics to sound wave monitoring
