Abstract

The auditory effects caused by the outdoor concert are discussed in this paper. The analysis is based on the computation results obtained by means of supercomputing PL-Grid infrastructure and specific computational algorithms developed by the authors. The software consists of the outdoor sound propagation module and psychoacoustical noise dosimeter. The simulation was performed by means of real music recordings and the following outdoor propagation conditions were taken into account: speaker directivity, ground effect, building reflection, distance attenuation, and sound absorption by the atmosphere. On the basis of the proposed methodology the dynamic (one minute time resolution) psychoacoustic maps of hearing threats for considered area were created expressed by TTS (Temporary Threshold Shift) values in critical bands. Moreover, the results include also maps of sound level and noise dose values.
