The article’s research subject concerns soundscape acoustic perception and human perception. The article aims to support decision-making processes, based on the subjective assessment of green areas by visitors, allowing modeling of planning strategies in urban green areas. This would allow creating a friendly soundscape and managing it sustainably. The need to create a musical landscape can contribute to finding a new function and attractive form for the studied areas now and in the future. Research carried out for selected city parks in Bydgoszcz (Poland) took into consideration people’s responses in assessing the soundscape. Surveys conducted in selected parks provided information on noise sources and how consumers perceive noise during their stay in the park. A question about feeling described the reception of sound sources’ intensity by respondents (level of feeling: low, medium, high, and very high). The completed studies allow to “translate” subjective sound level responses to the numerical values of the correlation using fuzzy cognitive maps. The implemented scenarios show the possibility of using tools supporting the decision-making process in urban planning, taking into account existing acoustic conditions.

“…A commonly used solution to classify linearly inseparable data is a projection of the original data to the function space (space of attributes), in which the data are linearly separable with a probability close to 1. Usually, the dimension of the space of attributes-K is a lot larger than the dimension of the space of the original-N, and a carried-out transformation of one space into another is a non-linear transformation [66]. The graphic presentation of the non-linear transformation of the linearly inseparable data is shown in Figure 5a After a non-linear transformation, the data become linearly separable and they can be separated by one separation plane.…”

This paper addresses the problem of noise in spa protection areas. Its aim is to determine the delimitation of the areas that exceed a permissible noise level around the sanatorium on the example of a health resort in Inowrocław. The determination of the exceedance of permissible noise levels allows us to develop directly effective local policy tools to be included in planning documents. In order to reduce noise infiltration, it is important to define environmental priorities. Taking into account their impact on the health of users in the protection area, environmental priorities enable us to introduce additional elements to street architecture. In order to properly manage space, in accordance with the idea of sustainable development, zones of environmental sensitivity-and their socio-environmental vulnerability-have been designated for assessing damage (exceeding permissible noise in health facilities) and defining methods of building resilience (proper management). This has provided the basis for a natural balance optimized for the people living in these areas. To achieve the goal above, non-linear support vector machine (SVM) networks were used. This technique allows us to classify the linearly inseparable data and to determine the optimal separation margin. The boundaries of the areas which exceeded permissible noise levels (separation margin) were estimated on the basis of noise pollution maps, created by means of the SVM technique. Thus, the study results in establishing buffer zones where it is possible to use varied land utilization in terms of form and function, as described in the planning documents. Such an activity would limit the spread of noise.Sustainability 2019, 11, 4199 2 of 17 it is important to properly manage and recognize social, environmental and health vulnerabilities. "Noise sensitivity" is defined as an individual and increased probability of perceiving sounds as unpleasant [8][9][10][11]. Moreover, getting used to excessive noise levels causes indifference, which is caused by exposure to a hazardous situation [12][13][14][15][16].Noise can be characterized by its source (e.g., anthropogenic or natural causes) or by specific physical values, such as power, intensity, frequency or duration. It should be noted that its relevant parameters refer not only to strictly objective values considered to be unpleasant or harmful but also, to the same extent, to the places where common sounds will cause unwanted or disturbing effects [17][18][19]. Organized urban spaces are treated like resources directly used by local residents. The conditions of these spaces decide also on the possibilities for creating a proper base for planners who, to a greater or lesser degree, introduce quantitative and qualitative changes in the area [20,21].It is important then, to analyze the acoustic situation. The determination of physical parameters such as density, open spaces, their shape, the greenery and the location of the buildings has a significant effect on the noise spread in the environment [18,22]. Maps are a...

“…Combining these technologies with classic highprecision measurements allows us to capture a broader spectrum of features of the tested objects. Such solutions are successfully used in inventory measurements and monitoring of both small [9] and larger facilities [10,11] or large areas exposed to various types of risks [12,13].…”

Modern measuring technologies give the means to perform tasks previously impossible with conventional methods. Their main advantages include reduced time consumption and higher measurement precision. Contemporary displacement and deformation studies of engineering structures often involve application of laser technologies, which are characterised by high precision of measurements. This article presents an analysis of results obtained from measurements of changes in the geometry of an engineering structure in which two complementary measuring technologies were used, i.e. tachymetric measurement with a Leica TDRA6000 laser station and laser scanning with a 3D FARO Focus S150 scanner. The utilised laser station enabled determination of 3D displacements in the local control point network installed on the studied structure as well as transfer of point clouds obtained from laser scans into a uniform coordinate system. The hybrid technology employed and the measurement method used ensured that the accuracy of the determined displacements and deformations of the structural components of the structure was high. The described measurement and result processing technology makes it possible to comprehensively analyse the geometric performance of structures, which consequently leads to the development of more complete conclusions concerning prevention of adverse effects of displacements and deformations in engineering structures.
