Simulation, Auralization and Their Verification of Acoustic Parameters Using Line Arrays

Document Thumbnail

An existing room with installed line arrays was investigated by means of corresponding measurements. Furthermore in EASE4.1 a simulation of direct sound coverage as well as of the room impulse response has been done, to derive as a result sound levels and intelligibility measures. Here different approaches have been utilized including a statistic field approximation and the room acoustic algorithms of EASE AURA. Additionally the same acoustic parameters have been measured using the measurement software EASERA. The comparison of measured and simulated results showed a good correlation. To additionally confirm the similarity, a comparison of auralized files was performed which showed deviations audible only for experts.
