¿Son necesarias tantas curvas de referencia en aislamiento acústico?

Abstract

[ES] Después de una breve consideración sobre la conveniencia y fundamentos psicoacústico de las valoraciones globales de las magnitudes de aislamiento acústico de las curvas de referencia se consideran las características y propiedades de las curvas de referencia previstas para valoración de la mejora global del aislamiento frente al ruido aéreo de revestimientos livianos. Se indican los intervalos frecuencia donde les mayor la eficacia de un revestimiento acústico en igualdad de restantes condiciones y se concluye en que para valorar adecuadamente el efecto global de un revestimiento hay que usar como curva de referencia el propio divisorio sobre el que se va a aplicar, siendo las dos curvas de referencia propuestas en el documento ISO/DIS una solución de compromiso para no incrementar el numero de parámetros que definen un producto acústico.

[EN] Alter a brief view of single number quantities and psychoacoustic fundamentals used in sound insulation, reference curves provided in the new standard (a DIS level ISO project) as a method for globally assessing of airborne sound insulation improvements of lightweight wall linings are dealt with. By using a numeric simulation model the properties of airborne sound insulation improvements of wall linings resulting from that single number ratings are discussed: among then the frequency intervals of higher efficiency and the insignificance of the incident noise spectrum are noteworthy. Another important conclusion concerns the variability of global improvement as a function of the reference curve, the two curves involved in the standard project represents a certain compromise of simplicity.
