simulación acústica de salas, validación de código informático, comparación internacional, índices de articulación, aurilizaciónResumen
Este artículo aborda la validación de los resultados de la simulación del código computacional de acústica de salas del Software RAIOS 7. El programa calcula las respuestas impulsivas monoaurales y binaurales (RIR y BRIR), así como los parámetros de calidad acústica en una sala dada, por pares. fuente-receptor especificado. Para validar las respuestas de impulso monoaural y el cálculo de los parámetros acústicos, los resultados de la simulación se comparan con los resultados de otros programas, así como con los datos de medición en la habitación publicados anteriormente. La sala simulada es una de las utilizadas en la última intercomparación internacional de simuladores. Se muestra que el código computacional en estudio presentó desviaciones similares a los demás programas. Para validar las respuestas impulsivas binaurales se utilizan pruebas de articulación. Las pruebas de inteligibilidad se realizan en cinco aulas de diferentes tamaños. Las mismas habitaciones se modelan en código de computadora para generar las respuestas de impulso binaurales para los pares fuente-receptor posicionados como en la habitación real. Las mismas señales de sonido utilizadas en las pruebas reales se mezclan con las respuestas impulsivas binaurales simuladas, generando aurilizaciones. Finalmente se realizan pruebas de articulación y se comparan sus resultados con pruebas realizadas en salas reales, indicando errores inferiores al 5%.
