Figure 5From: Quantification of the exposure and effects of road traffic noise in a dense Asian city: a comparison with western citiesThe %HSD by road traffic noise. The data points are the %HSD within each 1Â dB interval of exposure over the Lnight range of 42 to 69Â dB. The best fit quadratic exposure-response regression model is shown, together with 95% upper and lower confidence bounds.Back to article page
