heal.abstract	The aim of the present study is mapping patterns related to noise pollution and the acoustic environment -in a broader context- in the urban area of Athens, Greece. European Union considers environmental noise to be a significant environmental issue and has thus introduced a directive (2002/49/EC) concerning "assessment and management of environmental noise". The primary goal of this thesis is to present a holistic approach which combines elements of two basic methodologies related to acoustic environment studies: a) noise mapping and b) soundscape approach. The methodology implemented is significantly influenced by the article of Margaritis & Kang (2017). The main inputs are environmental noise measurements and perceptual soundscape recordings. A total of 483 locations were selected through systematic sampling and distributed equally across an area of 4.83 km2 which includes the commercial triangle of Athens, the National Garden, the area surrounding the archaeological site of the Acropolis and four additional districts (Metaxourgeio, Plaka, Kerameikos, Exarcheia). The unsampled locations are assigned spatially interpolated values using the Ordinary Kriging method. The results feature three noise pollution maps (LAeq,30 sec, L10 and L90 indexes) and three soundscape maps which reflect the way human ear perceives the presence of sounds. Depending on their source, these sounds are categorized into “human”, “natural” and “technological”. Additionally, through the conduct of Geographically Weighted Regressions, it was examined whether the dispersion of environmental noise levels can be explained by the spatial distribution of soundscape data. Furthermore, a visualization of the predominant soundscape of the area was attempted through the process of cartographic overlay. Regarding the comparison of environmental noise levels with the recordings of perceptual soundscape data, it is deduced that the dispersion of all three indicators is explained to a significant degree (73% for L10, 78% for LAeq, 30s and 80% for L90 index) from the soundscape recordings, which consequently implies good adaptability of the model. Moreover, the spatial autocorrelation test (Moran’s I) indicates that in all three cases the errors have constant variance, even spatial distribution and arise through stochastic processes. The adaptability of the model is therefore further strengthened. Four important findings emerge from the analysis. Firstly, areas with high levels of noise pollution (northern and northern to central locations) are characterized by high to moderate presence of technological and absence of human and natural sounds. Secondly, in the southern central region there is a simultaneous presence of all sound sources; moderate-high technological, moderate human and low natural. This region is characterized by moderate to low environmental noise levels and is distinguished by several commercial activities. Thirdly, areas with absence of technological sounds in which combinations of human and natural sounds prevail are in the south and southwest where low levels of environmental noise are detected. These recreational districts are reasonably distanced from the noisy centre. Finally, areas featuring a moderate presence of technological and natural sound sources where human ones are absent are mostly urban green spaces built in proximity to the main road network as the noise produced by the latter does not leave the adjacent acoustic environment unaffected.	en
