Synthesis of a Virtual Urban Soundscape
AbstractThe main research question addressed in this article is to find out to what extent it is possible to predict statistical noise levels such as L5 and L95 on an urban public square, based on the information about the square’s functionality, the activities going on, and the architecture of the surrounding buildings. The same information is also exploited to auralize the soundscape on the virtual square, in order to assess the disturbance perceived by people of the traffic noise by means of laboratory listening tests, which are based on binaural sound recordings acquired in situ and incorporated in simulations to evoke typical acoustical situations. Auralizations were carried out by two calculation algorithms (ray-tracing and image source method) and two acoustic scenarios (an anechoic situation and a virtually reconstructed square in Odeon®). The statistical noise levels, calculated from the auralized soundscapes, compare well with measurements in situ. The listening test results also show that there are significant differences in people’s perception of traffic noise, depending on their origin.
