Traffic noise can lead to cortical and autonomic activation, disrupt sleep and impair physical and mental restoration. We used the odds ratio product (ORP), a validated continuous measure of sleep depth based on automatic analysis of physiologic sleep data in 3-second epochs, to investigate temporal changes of sleep in response to nocturnal noise events. Seventy-two healthy participants slept for 10 nights in a laboratory, during which we measured sleep with polysomnography. In 8 nights, participants were exposed to 40, 80 or 120 road, rail and/or aircraft noise events at 45-65 dB LAS,max. Event-related change of ORP relative to pre-event baseline was analysed with linear mixed models. ORP increased during aircraft, road and rail noise, reflecting reduced sleep depth and quality, and there was a greater response to road and rail noise than to aircraft noise. The clinical relevance of event-related elevations of ORP is currently unknown, and warrants further investigation.
