New methods for predicting soundscape

Abstract

The ISO 12913 series Soundscape standard provides procedures to describe the acoustic environment in context and cognition and to interpret it with the help of psychoacoustics. This presupposes the presence of an acoustic environment and to interview people living in this soundscape. As during the pandemic interactive communication was limited, a greater focus was led on creating artificial acoustic environments. With the help of a simulation method, a human-focused acoustic virtual environment for the auralization of traffic noise is implemented based on existing traffic data. Traffic noise is an important attribute for the design of attractive living spaces. A reliable prediction of this burden in urban development and traffic planning offers a great potential. For this purpose, source, transmission, and receiver properties as well as movement profiles from traffic data and possible noise reduction measures are considered. Methods and concepts for simulation as well as human perception are focused. The potential to exploit available data from traffic and planning is demonstrated using example scenarios. The simulation enables the auralization and evaluation of the perception of traffic noise in different scenarios.
