This paper presents investigations into a comparative assessment of the effects of low and high frequency noise in relation to personality traits. The high and low-frequency noises used are produced in the research laboratory using CoolEdit software. 80 candidates are exposed to equivalent continuous sound pressure level of 65 dBA of low and high frequency noise in an acoustic room with a 2 week interval. After 1 hour of exposure to noise, participants were asked to complete noise annoyance scale, Weinstein noise sensitivity questionnaire, loudness perception. The results obtained indicate that there is a significant difference between annoyance and perception of low frequency noise in comparison to annoyance and perception of high frequency noise, but no significant difference is noted between sensitivity to low and high frequency noise. The multivariate analysis of covariance test is applied, which reveals that personality traits have a significant effect on sensitivity to low and high frequency noise, annoyance due to low and high frequency noise, loudness perception of low frequency noise, but no interaction effects are found. It is further shown that personality traits are more effective on sensitivity, annoyance and loudness perception to high frequency noise than those of low frequency noise, and such effects are not only influenced by severity of noise, but also by personality traits and frequency components.
