Abstract

This research study presents rough set-based decision systems applications to the acoustical domain. Two areas are reviewed for this purpose, namely music information classification and retrieval and noise control. The main aim of this paper is to show results of both measurements of the acoustic climate and a survey on noise threat, conducted in schools and students' music clubs. The measurements of the acoustic climate employ multimedia noise monitoring system engineered at the Multimedia Systems Department of the Gdansk University of Technology. Physiological effects of noise exposure are measured using pure tone audiometry and otoacoustic emission tests. All data are gathered in decision tables in order to explore the significance of attributes related to hearing loss occurence and subjective factors that attribute to the noise annoyance. Future direction of experiments are shortly outlined in Summary.
