Wiele badań pokazuje, że hałas jest szkodliwy dla ludzi i zwierząt. Również nadmiar sztucznego światła wpływa destrukcyjnie na ekosystemy.

Traffic related noise is currently considered as an environmental pollution. Paper presents results of multidirectional study attempting to serve urban traffic without the need to erect noise barriers interfering urban space. Initial concept of the road expansion included construction of 1000 m of noise barriers dividing city space. Improvement in the acoustic conditions after construction completion is possible due to the applied noise protection measures: vehicle speed limit, smooth of traffic flow, use of road pavement of reduced noise emission and the technical improvement of the tramway.

In the contemporary world, where globalization and industrialization are progressing, there are no large cities that do not generate noise. Noise is usually connected with industrial areas, airports, circulation spaces or city centres. However, it is increasingly felt in places that have previously been associated with peace and quiet, such as suburban housing estates, recreational areas, urban forests, and parks. Noise penetrates public space, robbing this landscape of silence, pleasant sounds or positive sounds. The negative impact of noise on the life processes of humans and animals is worrying. Sound quality should be treated as an element of landscape quality, therefore it should be considered in planning processes or urban space development projects. The aim of this paper is to present an analysis of the soundscape in city space and of the level of noise in Centralny Park in Olsztyn, Poland. Guidelines were also drawn up for the proper management of park space in terms of reducing noise impact, and a model (recommendation) for analysed areas was formulated. The study consisted of:
– measurements of sound pressure levels (SPL) at selected points in two periods,
– interviews with park users and the preparation of a mental map,
– preparing a design scheme for a redesign of the park.
The results confirmed the difference between SPL in the leafless and leafy period. They also showed a clear relationship between the perception of sounds and well-being in the park.
