The WHO environmental noise guidelines for the European Region are in the final stages of updating. The guidelines not only consider new evidence associating noise exposure with health outcomes but also new noise sources and where possible, quantify the risk of these health effects with an incremental increase in noise exposure. In addition to transport noise (aircraft, rail and road traffic), wind turbine and leisure noise are considered. The health outcomes reviewed and covered in the guidelines include annoyance, cardiovascular and metabolic effects, cognitive impairment, quality of life, mental health and well-being, hearing impairment and tinnitus, adverse birth outcomes, and effects on sleep. Moreover, the guidelines address different types of interventions and their effects. The development of WHO guidelines follows a rigorous framework to ensure unbiased systematic review of evidence and formulation of public health recommendations. The Grading of Recommendations, Assessment, Development and Evaluations (GRADE) approach was applied to assess the quality of evidence. This ICBEN 2017 session presents the main outcomes of the systematic reviews of evidence on health outcomes and interventions. The systematic reviews will be published in a special issue of the International Journal of Environmental Research and Public Health (IJERPH).
