In this work, a new approach to validate computer modeling auralizations by using articulation indexes is presented. The generation of acoustical virtual reality with the proprietary computer code RAIOS is briefly described. The code simulates the room acoustics, including specular and diffuse reflections, and a set of artificial neural networks provides the room’s binaural impulse responses at selected points in the audience region. Then, these responses are convolved with anechoic signals to generate virtual acoustical realities. In the sequel, the impulse responses at some room’s positions are measured and the convolution with the anechoic signals is provided to obtain a virtual articulation index. Finally, the computer modeling auralizations are also reproduced to the subjects and the obtained articulation index results are compared for validation purposes.
