In research are used objective and subjective sound features on the development of noise annoyance assessment model in urbanized environment. They represent a quantitative and qualitative evaluation of the acoustic signal. The relation of objective features in subjective features is the direction of research on the development of noise annoyance evaluation model developed for several years. The carrier of information about the characteristics of sound in the environment is an acoustic signal coming from noise sour...

The article presents a way of identifying and modeling sound features in an urbanized environment. The subject of article is focused on the problem of noise pollution modeling coming from moving technical objects, i.e. vehicles that are potential sources of noise. In this case, the vehicles are treated as multi-source acoustic energy emission objects. The proposed approach assumes the occurrence of variable relations in the system: source-path propagation-receiver. In the presented method the information carrier i...

According to the existing Directive 2002/49/WE the task of identification and forecasting of noise pollution in the urban environment are carried through acoustic maps technology. The parameters designated in acoustic maps are limited to the quantitative size of evaluation of the environment exposed to the effects of noise sources, e.g. LAeq, LDEN, Lnight. The determined values of these parameters are fundamental to the decision пїЅ making process in the terms of noise reduction. The results of undertaken research...

In studies on the assessment of the impact of environmental noise sources, depending on the objective set, there are used various supporting models and technologies. In the article, there was carried out the analysis of the selection of physical and psychoacoustic variables caused by the noise sources. They were determined the basic psychoacoustic measures of sound quality for registered acoustic signals in urban environment. The results were compared with the results obtained in the experiment. There was carried ...
