Abstract

BACKGROUND: Exposure to traffic noise could play an important part in inducing psychological disorders which in turn can affect individuals' cognitive and mental performance. OBJECTIVE: The aim of this study was to determine the effect of traffic noise exposure on the cognitive performance with regard to subjects' personality traits. METHODS: Sixty students with normal hearing and vision took part in this experimental study. In order to simulate the traffic noise condition of Tehran, the noise from several busy streets was first carefully recorded. Later on, the subjects were exposed to this recorded noise in an anechoic chamber. Also, the NEO-five factor inventory questionnaire and the continuous performance test were used to assess personality traits and cognitive performance of participants respectively. RESULTS: The results showed that the cognitive features of the study, such as reaction time and the number of commission/omission errors in continuous performance testing increased significantly after exposure to the traffic noise (p < 0.05), and among the personality traits, only the neuroticism has a significant correlation with response time in the continuous performance tests (p < 0.05). CONCLUSIONS: Apart from the effect of traffic noise on cognitive function, the findings of this study confirmed that Neuroticism (one of the personality traits) also significantly affect the cognitive performance of individuals when they are exposed to traffic noise in laboratory conditions. © 2022 - IOS Press.
