Living in a quiet area provides health benefits such as increased quality of life and well-being. Nearby access to quiet areas can also offer psychological restoration and can help in reducing noise annoyance reactions. Quiet areas are not only beneficial for human health but also help to protect areas of valuable habitat. The Environmental Noise Directive (END) recognises the need to preserve areas of good acoustic quality, referred as “quiet areas”. However, the data reported as part of the END contains little information on how the countries, regions and cities define and protect quiet areas in their territories and whether there has been a significant improvement in designation and protection of these areas over the past years. The aim of this paper is to present an overview of how countries define and protect quiet areas in Europe. This is achieved using data from case studies comprised of online questionnaires, which were completed by noise representatives of different countries, regions and cities. In addition to the analysis of the questionnaires, a combined spatial assessment of noise exposure, land use and land cover data for areas potentially unaffected by noise pollution in European cities is presented for 2012 and 2017.
