Utilisation of psychoacoustics in technical practice

Abstract

Psychoacoustics is currently a powerful tool for optimizing the acoustic properties of sounds of machines, equipment and products in industry and in the home by thorough analysis and subsequent correction of psychoacoustic parameters (such as roughness, sharpness, volume, sound color, etc.) in order to achieve acceptability for man. It should be noted that the perception of sound (noise) by man is of a subjective nature and heavily depends on a particular person and his current disposition. The psychoacoustic parameters (roughness, sharpness, volume, color, tone, fluctuation force, subjective duration, and sound height) provide the foundation for solving many technical problems in practice. With respect to the application of psychoacoustics in practice, a relatively new scientific department has created a so-called acoustic product design that aims to optimize the acoustic effects of products on its potential users and their surrounding
