In September 2018 researchers from Bulgaria published their review of the medical scientific literature to assess the association between residential road traffic noise and the risk of hypertension in adults. This had been the subject of a World Health Organisation (WHO) evidence based review but since its publication an increasing amount of large-scale research had been published hence this review. A total of 9 studies were included in the review. The studies were of moderate quality and no publication bias was identified. Results showed that residential road traffic noise was associated with a higher risk of hypertension in adults, but that the risk was lower than previously reported.
