Figure 2: The association between road traffic noise exposure (LAeq,6-22 hr) and the prevalence of hypertension and angina pectoris, and cardiovascular mortality, derived from Dutch studies. The dotted line corresponds to no effect of road traffic noise exposure. The study effect estimates (RR5dB and their 95% confidence intervals) were derived according to the methods described in Van Kempen et al., 2002[6]
