Creation of virtual sound environments using geometrical acoustics and finite elements method
Creation of virtual sound environments using geometrical acoustics and finite elements method
In this paper, the sound pressure field of a small room was analysed using geometrical acoustics methods, a wave equation method in the frequency domain and binaural impulse response measurements in order to create virtual sound environments for specific source-receiver positions. The GA methods were applied using CATT-Acoustic, where the Randomised Tail-corrected Cone-tracing was implemented in order to generate binaural impulse responses. The wave equation technique was applied using ACTRAN, which utilizes FEM to estimate the sound pressure field. Afterward, a hybrid method combining GA and FEM was implemented via Off-line signal processing to create binaural impulse responses using the frequency ranges where each technique provides more reliable results. Finally, the realised virtual sound environments were verified against the binaural impulse response measurements by means of objective and subjective methods.

Abstract
In this paper, the sound pressure field of a small room was analysed using geometrical acoustics methods, a wave equation method in the frequency domain and binaural impulse response measurements in order to create virtual sound environments for specific source-receiver positions. The GA methods were applied using CATT-Acoustic, where the Randomised Tail-corrected Cone-tracing was implemented in order to generate binaural impulse responses. The wave equation technique was applied using ACTRAN, which utilizes FEM to estimate the sound pressure field. Afterward, a hybrid method combining GA and FEM was implemented via Off-line signal processing to create binaural impulse responses using the frequency ranges where each technique provides more reliable results. Finally, the realised virtual sound environments were verified against the binaural impulse response measurements by means of objective and subjective methods.
