The possibilities of using other models for predicting the binaural room impulse responses for low frequencies have been studied. This is due to the limitations of geometrical acoustics, which forms the basis for these programs.

JO - Journal of the Audio Engineering SocietyĪB - Wide-frequency-range auralization, such as needed for car audio, cannot be accomplished using currently available software for architectural acoustics modeling, since these are optimized for large rooms. TI - Experimental Auralization of Car Audio Installations Results from preliminary listening tests are emmanuel and kleiner, mendel and dalenbäck, bengt-inge and svensson, peter}, The signal processing for joining the results from low- and high-frequency modeling is described in detail. Different binaural approaches to low-frequency modeling are described. Finite-element and boundary-element models are being used at low frequencies, in conjunction with an augmented geometrical acoustics model for high frequencies to facilitate wide-frequency range auralization of, for example, car audio installations. doi:Ībstract: Wide-frequency-range auralization, such as needed for car audio, cannot be accomplished using currently available software for architectural acoustics modeling, since these are optimized for large rooms.
