“…Our L eq and L max measures indicate exposure to very loud noise for periods somewhat comparable to the daily ranges associated with increased cardiovascular and psychosomatic health risks. 10,12,15,17,18,20,[33][34][35][36][37] However, we warn that these studies generally treated periodic exposures throughout the day, such as those due to proximity to rail systems or traffic. Most BART trips are likely to extend beyond one line segment; for round-trip commuters, such exposure will double in the course of a day.…”

“…10,17 Findings have also shown that children living amid chronic noise have elevated levels of stress-induced hormones as well as elevated blood pressure. 18,19 There is also evidence of negative behavioral outcomes of noise exposure as well, 10,20 including negative behavioral effects of noise on children's cognition, concentration and memory, 17,[19][20][21] and on school performance. 22 The level of noise on trains results from many interacting factors, 23 including wheel roundness (i.e., deviation from perfectly circular) and wheel trueness (side-toside wobble in shape), rail condition (e.g., "corrugation," banking, points, etc.…”

A Study of Riders' Noise Exposure on Bay Area Rapid Transit Trains

Excessive noise exposure may present a hazard to hearing, cardiovascular, and psychosomatic health. Mass transit systems, such as the Bay Area Rapid Transit (BART) system, are potential sources of excessive noise. The purpose of this study was to characterize transit noise and riders' exposure to noise on the BART system using three dosimetry metrics. We made 268 dosimetry measurements on a convenience sample of 51 line segments. Dosimetry measures were modeled using linear and nonlinear multiple regression as functions of average velocity, tunnel enclosure, flooring, and wet weather conditions and presented visually on a map of the BART system. This study provides evidence of levels of hazardous levels of noise exposure in all three dosimetry metrics. L eq and L max measures indicate exposures well above ranges associated with increased cardiovascular and psychosomatic health risks in the published literature. L peak indicate acute exposures hazardous to adult hearing on about 1% of line segment rides and acute exposures hazardous to child hearing on about 2% of such rides. The noise to which passengers are exposed may be due to trainspecific conditions (velocity and flooring), but also to rail conditions (velocity and tunnels). These findings may point at possible remediation (revised speed limits on longer segments and those segments enclosed by tunnels). The findings also suggest that specific rail segments could be improved for noise.

“…At the 56 locations successfully monitored for noise, 55 samples were successfully monitored for PM 2.5 and BC (one location's PM 2.5 measurement did not pass filter QA/QC checks after monitoring and the sample was removed from further analysis). All sites were monitored for NO 2 and NO.…”

“…Epidemiologic studies, for example, suggest higher risks of cardiovascular disease, including myocardial infarction and hypertension among people exposed to higher levels of ambient noise, particularly traffic noise. [1][2][3][4][5] Ambient noise exposures have been linked to a variety of physical and mental responses, including effects on cardiovascular endpoints 6 and impairment of cognitive development in children. 7 Nighttime noise exposures may be especially harmful and have been associated with elevated blood pressure, 8,9 and a greater cardiovascular response when compared to daytime noise exposures.…”

Spatial Variation in Environmental Noise and Air Pollution in New York City

et al. 2014

Exposure to environmental noise from traffic is common in urban areas and has been linked to increased risks of adverse health effects including cardiovascular disease. Because traffic sources also produce air pollutants that increase the risk of cardiovascular morbidity, associations between traffic exposures and health outcomes may involve confounding and/or synergisms between air pollution and noise. While prior studies have characterized intraurban spatial variation in air pollution in New York City (NYC), limited data exists on the levels and spatial variation in noise levels. We measured 1-week equivalent continuous sound pressure levels (L eq ) at 56 sites during the fall of 2012 across NYC locations with varying traffic intensity and building density that are routinely monitored for combustion-related air pollutants. We evaluated correlations among several noise metrics used to characterize noise exposures, including L eq during different time periods (night, day, weekday, weekend), L dn (day-night noise), and measures of intermittent noise defined as the ratio of peak levels to median and background levels. We also examined correlations between sound pressure levels and co-located simultaneous measures of nitric oxide (NO), nitrogen dioxide (NO 2 ), fine particulate matter (PM 2.5 ), and black carbon (BC) as well as estimates of traffic and building density around the monitoring sites. Noise levels varied widely across the 56 monitoring sites; 1-week L eq varied by 21.6 dBA (range 59.1-80.7 dBA) with the highest levels observed during the weekday, daytime hours. Indices of average noise were well correlated with each other (r9 0.83), while indices of intermittent noise were not well correlated with average noise levels (rG0.41). One-week L eq correlated well with NO, NO 2 , and EC levels (r=0.61 to 0.68) and less so with PM 2.5 levels (r=0.45). We observed associations between 1-week noise levels and traffic intensity within 100 m of the monitoring sites (r = 0.58). The high levels of noise observed in NYC often exceed recommended guidelines for outdoor and personal exposures, suggesting unhealthy levels in many locations. Associations between noise, traffic, and combustion air pollutants suggest the possibility for confounding and/or synergism in intraurban epidemiological studies of traffic-related health effects. The different spatial pattern of intermittent noise compared to average noise level may suggest different sources.Kheirbek, Ito, Kim, Johnson, and Matte are with the New York City

“…The reported effects on sleep disturbance tend to be a reduction in the sleep period, arousals, awakenings, sleep stage modifications and autonomic responses (e.g. change in heart rate) (Vallet et al, 1983;Carter, 1996;Babisch et al, 2005). Moreover, the reduction in sleep quality has secondary impacts (generally felt the day after disturbance) including fatigue, low work capacity, reduced cognitive performance, changes in daytime behaviour as well as mood changes and associated negative emotions.…”

The World Health Organisation has recently acknowledged that contrary to the trend for other environmental stressors, noise exposure is increasing in Europe. However, little research has been conducted on environmental noise exposure to handling activity at shipping ports. This paper reports on research examining the extent of noise exposure for residents within the vicinity of Dublin Port, Ireland using the nation's largest port terminal as a proxy for port noise. In order to assess the level of exposure in the area, long-term measurements were undertaken at the most exposed residential façade for a period of 45 days to determine the extent of night-time exposure was above levels recommended by the World Health Organisation. The indicators L90, Leq and LMax were used to determine exposure levels. The results show that exposure is above night-time guideline limits set down by the WHO and is above Irish levels for triggering a mitigation response and highlight the extent to which port noise can be a significant environmental stressor. The research also investigated the extent of low-frequency noise (which is associated with greater health issues) from night-time port handling activity and found a significant low-frequency component indicating the negative health issues that might arise from port noise exposure more generally. We also undertook semi-structured interviews with residents to qualitatively assess the self-reported impact of prolonged night-time noise exposure for local residents.
