Abstract

Wide frequency range auralization, such as needed for car audio, cannot be accomplished using currently available software for architectural acoustics modeling, since these programs are optimized for large rooms. This is due to the limitations of geometrical acoustics that form the basis for these programs. The possibilities of using other models for prediction of the binaural room impulse response for low frequencies have been studied. In this work, FEM and BEM models are used at low frequencies, in conjunction with an augmented geometrical acoustics model for high frequencies, for wide frequency range auralization of car audio installation. The binaural approach to the low-frequency modeling is described. The signal processing for joining the results from low- and high-frequency modeling is described. Results from preliminary listening tests are discussed.
