Cross-country variation in psychophysiological responses to traffic noise exposure: Laboratory experiments in India and the UK

Abstract: Traffic noise exposure has detrimental effects on human health, including both auditory and nonauditory impacts. As one such nonauditory factor, individuals and communities in different countries may exhibit different patterns of noise sensitivity and corresponding tolerance levels, leading to a change in overall noise perception. This paper investigated the cross-country differences in psychophysiological responses to traffic noise exposure between Indian and British individuals. A psychophysiological signal-based [heart rate variability (HRV) and skin conductance response (SCR)] listening experiment was conducted in India and the United Kingdom to analyze changes in noise perception and psychophysiological responses resulting from exposure to the same noise stimuli. HRV analysis indicated greater cardiovascular impact in the British group due to a significant increase in heart rate (W = 653, p < 0.01). Also, a significant increase in the SCR (W = 535, p < 0.001) was noted, indicating a greater level of physiological stress among British participants due to traffic noise stimuli. These findings highlight the difference in noise perception due to cross-country variation using psychophysiological responses. Understanding these cross-country differences can inform targeted interventions and policies to mitigate the adverse effects of traffic noise on human well-being.
