Abstract:
Ergonomics aspects in working environment have grown the awareness of the need of improving sound quality of machinery sound as well as to reduce its sound. Psychoacoustics supplies important tools (with more sophisticated methods employing ear–related metrics) in order to evaluate the sound quality. It is well recognized that jury (or panel) evaluation provides a reasonable guide to value the quality of machinery noise in working environment. The following work belongs to a project dealing with the studies and the applications of psychoacoustic methods in order to evaluate the sound emitted by post–sorting machines. After a measurement campaign, two kinds of jury tests have been performed, one based on pair comparison forced-choice trials, the other on magnitude estimation. The results allowed us to define a robust scale of pleasantness of typical sounds generated in a wide variety of post–sorting machines, in different environments and under different operating conditions.
