ABSTRACT
At
present, acoustic maps are used in management tasks of assessing the acoustic
climate of the environment. The methods of modeling and simulation of noise
assessment indices are used for this purpose. These indicators represent the
quantitative spatial distribution of the sound level. Research on the
perception of sounds has been carried out for many years and it has been found
out that subjective acoustic impressions are of significant importance. This
paper proposes a quantitative and qualitative approach to the assessment of
noise in the urbanized environment using acoustic maps. The features of sound
quality and their importance in the modeling of noise annoyance assessment have
been described. Acoustic measurements were made on the example of the selected
case study in the environment. The results of modeling physical indicators of
road noise in the environment with the use of acoustic maps are presented. Based on the registered acoustic measurements, the
results of the sound quality features of the acoustic signals in the time and
frequency domain are presented below. The determined values of sound quality
features are a valuable source of information in the field of noise perception
assessment. A model for assessing road noise has been proposed. It includes
sound quality features which can be used in acoustic maps. As part of the discussion of the results, it was found
that the obtained results of quantitative and qualitative analysis of the
acoustic signal parameters can be the basis for the development of the road
traffic noise annoyance assessment model using acoustic maps technology.
