Factors influencing subjective noise sensitivity in an urban population

This study was designed to define the individual variables influencing subjective noise sensitivity in an urban population and to investigate the distribution of subjective noise sensitivity with regard to noise exposure. A general questionnaire, a ten-graded noise annoyance scale, the Weinstein's Noise Sensitivity Scale, and the Eysenck Personality Questionnaire were applied to a sample of 413 inhabitants of Belgrade. Distribution of noise sensitivity scores was normal and independent of noise exposure. No significant differences in average noise sensitivity scores were observed concerning gender and exposure to low (Leq < 55 dBA), and high level of traffic noise (Leq > 65 dBA). Multiple regression analysis revealed that neuroticism was the best individual predictor for SNS, for both sexes in the noisy area and for women only, in the quiet area (P < 0.001). Age, education level and introversion were not significantly related to noise sensitivity. Positive relation between reported noise annoyance and noise sensitivity was highly significant (P < 0.0001).
