Klimat akustyczny polskich uzdrowisk = The acoustic climate of Polish health resorts

Abstract

ilence and a good acoustic climate are important in every environment where human beings live (at home or the place of work, in the streets, on transport, etc.). Special attention needs to be paid to health resorts at which patients come to regenerate their health. However, the acoustic climate of spas is under the great impact of noise generated by local transport, neighbours, bars and restaurants, as well as by other communal sources. According to the legislative Act of the Ministry of Environment (the Dziennik Ustaw Official Journal of Laws of 2012, item 1109) in the core area of a health resort (the so-called zone A), the level of noise level cannot exceed 45 dB during daytime and 40 dB during night hours. In places close to roads the limits are slightly higher, at 50 and 45 dB respectively. These limits are very restrictive. However, we must remember that noise is very destructive and can involve many health disturbances; and health resorts are places in which sick and aged people come to improve their health status and to regenerate organisms. In spite of the great importance of an appropriate acoustic climate noise measurements are undertaken periodically and not monitored by public institutions. Acoustic climate studies are usually carried out by research institutes (e.g. the Institute of Geography and Spatial Organization of the Polish Academy of Sciences) every ten years, as a part of investigations to assess the quality of climatic conditions in health resorts. The aim of the paper is a general assessment of the acoustic climate in Polish health resorts and of trends as regards possible changes over the last 10 years (2009–2019) in 20 spas located in different bioclimatic regions of Poland. More detailed analysis is done for 2 coastal resorts (Świnoujście and Kołobrzeg). There are analysed factors influencing the acoustic climate and the effectiveness of actions undertaken by local authorities to reduce noise levels. Attention is paid to the spatial distribution of resort objects (sanatoria, hospitals etc.), the organisation of local transport, and the quality of roads and of the neighbourhood of cities in which tourist and administrative functions are pursued. As the most important factors influencing the acoustic climate are transport and activity of a multifunctional nature (with health-resort and tourist functions having contrasting expectations).
