- Abstract
- Noise from air-conditioner system installed in the ceiling of a classroom was evaluated to investigate the sound quality of air-conditioning noise. Harmonics of air-conditioning noise were removed and the sound pressure levels of the frequency bands from 250~630Hz were changed to control sound quality. Evaluation for refreshing sensation was conducted using a paired comparison method and the results showed that noise without harmonics were preferred to noise with harmonics. The noises which have larger level increases to the unchanged noise at 250~630 Hz were evaluated better in both of the noises with and without harmonics. Results of multiple regression analysis on psychoacoustic parameters and subjective preferences showed sharpness as a major affecting factor in describing the refreshing aspect of air-conditioning sound. 攀†책임저자;정회원, 한양대학교 전축대학E-mail : jyjeon@hanyang.ac.krTel:(02)2220-1795,Fax:(02)2291-1793* 정회원, 한양대학교攀攀
