A systematic review of evidence of the effect of transport noise interventions on human health
MetadataShow full item record
This paper describes a systematic literature review (1980-2014) of evidence on the effects of transport noise interventions on human health. Sources considered are roadways, railways, and air traffic. Health outcomes include sleep disturbance, annoyance, cognitive impairment of children and cardiovascular diseases. The interventions reviewed covered all noise management or control strategies practiced for all sources of transport noise. A previously developed model was applied to categorise studies (1). The review shows that evidence is thinly spread across different sources, outcomes and intervention types. While meta-analysis of the association between changes in level and outcome was not possible, some 43 individual transport source studies were examined as to whether the intervention lead to a change in health outcome and (for source, path and infrastructure change interventions) if the observed change in outcome was of a magnitude at least equivalent to that which would be predicted from a relevant exposure-response function, or exhibited excess response. The review showed that diverse intervention study designs, methods of analyses, exposure levels, and changes in exposure, restricted the analysis of findings. Further studies of transport interventions should be based on a protocol of measuring change in exposures, outcomes and confounders, not just changes in noise levels.
