“…This approach may possibly be because the urban form makes it difficult to model exposures accurately and thus additional modelling requires greater investment of resources, or because when it comes to health effects, there is a belief that they have unique pathways. Increasingly, however, studies are broadening to include coexistent pollutants, for example, both air pollution and noise in relation to cholesterol levels [5], and in relation to myocardial infarction [2]. As appears to be common in other studies as well, both Sorensen et al [5] and Tonne et al [2] found significant effects for air pollution and more modest associations for noise after controlling for air pollution [2,5].…”

Air pollution originating from road traffic is a known risk factor of respiratory and cardiovascular disease (both in terms of chronic and acute effects). While adverse effects on cardiovascular health have also been linked with noise (after controlling for air pollution), noise exposure has been commonly linked to sleep impairment and negative emotional reactions. Health is multi-faceted, both conceptually and operationally; Health-Related Quality of Life (HRQOL) is one of many measures capable of probing health. In this study, we examine pre-collected data from postal surveys probing HRQOL obtained from a variety of urban, suburban, and rural contexts across the North Island of New Zealand. Analyses focus on the covariance between air pollution annoyance and noise annoyances, and their independent and combined effects on HRQOL. Results indicate that the highest ratings of air pollution annoyance and noise annoyances were for residents living close to the motorway, while the lowest were for rural residents. Most of the city samples indicated no significant difference between air pollution- and noise-annoyance ratings, and of all of the correlations between air pollution- and noise-annoyance, the highest were found in the city samples. These findings suggest that annoyance is driven by exposure to environmental factors and not personality characteristics. Analysis of HRQOL indicated that air pollution annoyance predicts greater variability in the physical HRQOL domain while noise annoyance predicts greater variability in the psychological, social and environmental domains. The lack of an interaction effect between air pollution annoyance and noise annoyance suggests that air pollution and noise impact on health independently. These results echo those obtained from objective measures of health and suggest that mitigation of traffic effects should address both air and noise pollution.

“…Long-term noise exposure is considered as a health hazard1 and has been linked to non-auditory effects, including Alzheimer’s disease-like neuropathology23 and metabolic disorders4. Recent epidemiological studies have shown that chronic noise exposure is associated with increased risk of adiposity56, higher levels of cholesterol7 and development of diabetes8. A more recent experimental study also indicated that noise exposure at 95 dB SPL caused insulin resistance in mice, which was prolonged by longer noise exposure9.…”

Chronic noise exposure has been implicated in increased risk of diabetes. However, there is limited experimental evidence of the mechanisms linking chronic noise stress and glucose metabolism. We addressed this in the present study by examining glucose metabolism, immune response, and changes in gut microbiota/host inflammatory homeostasis in rats exposed to noise for 30 consecutive days. Chronic noise exposure increased blood glucose and corticosterone levels for at least 14 days after cessation of noise. Stressed rats also exhibited elevated levels of glycogen and triglyceride in the liver and impaired hepatic insulin production via insulin-induced insulin receptor/insulin receptor substrate 1/glycogen synthase kinase 3β signalling, which persisted for 3–14 days after cessation of noise exposure. Chronic noise altered the percentage of Proteobacteria and Actinobacteria in the gut, increasing Roseburia but decreasing Faecalibacterium levels in the cecum relative to controls. Immunoglobulin A, interleukin 1β, and tumor necrosis factor α levels were also elevated in the intestine of these animals, corresponding to noise-induced abnormalities in glucose regulation and insulin sensitivity. These results suggest that lifelong environmental noise exposure could have cumulative effects on diabetes onset and development resulting from alterations in gut microbiota composition and intestinal inflammation.

“…However, the role played by noise in the study was only slightly associated with cases of disease. Despite this finding, the author noted the difficulty in distinguishing an association between noise and air pollution was difficult to separate (Sørensen et al 2015).…”

“…Such studies mainly focused on NO2 and particulate matters, which are deemed as important indicators of traffic emissions. They were significantly associated with higher blood cholesterol, respiratory mortality and infections, and asthma for children under 4 (Sørensen et al 2015;Beelen et al 2007). However, the results suggested difficulty in explaining the interaction between these two pollutants.…”
