| Title |
An Experimental Study on the Reactions of the Dwellers upon the Road Traffic Noise in the Urban Residential Area |
| Abstract |
This study was carried out to compare the differencies in evaluating between the Loudness and Noisiness of road traffic noise and to delineate the appropriate indices in evaluating them by means of psycho-acoustic method.Thus, psycho-acoustic experiments in the real field were performed on 10 volunteer subjects and the Loudness and the Noisiness in 7 semantic scale reaction were analyzed in relation to the various noise indices. The results are summerized as follows:1.Between the Loudness and Noisiness, the lower standard deviation was detected at the case of Noisiness, which means the Semantic scale of the Noisiness is more appropriate to the evaluation of the Road Traffic Noise.2.In case of Loudness evaluation which evaluate only the magnitude of sounds, almost all indices except TNI were highly correlated.3.On the other hand, the Noisiness evaluation on which psychological factors affect, only L10, L90 and AI indices were highly correlated. |
