En la mayoría de las frecuencias medias para el tabique ligero, desarrollado a partir del 15 aditivo de la invención, presenta coeficientes de absorción superiores a 0,2, lo cual demuestra que el mortero ligero es de 3 a 8 veces más eficiente que el poliespuma. In most of the medium frequencies for the light partition, developed from the additive of the invention, it has absorption coefficients greater than 0.2, which shows that the light mortar is 3 to 8 times more efficient than polyfoam .
Para determinar las pérdidas de transmisión y el índice de aislamiento acústico de los hormigones ligeros, con densidades inferiores de 800 Kg/m3, se utilizan métodos 20 empíricos de cálculo. El procedimiento utilizado, aunque no es de gran precisión, ofrece una idea bastante acertada del comportamiento de este material ante los ruidos aéreos. To determine the transmission losses and the sound insulation index of light concrete, with densities lower than 800 Kg / m3, empirical methods of calculation are used. The procedure used, although not very accurate, offers a fairly accurate idea of the behavior of this material in the face of aerial noise.

Los resultados 25 obtenidos de muestran en la tabla 6. The method is applied to a sample of the light cellular concrete obtained with the additive of the invention, with a density of 705 Kg / m3 and a thickness of 100 mm. The results obtained are shown in table 6.
Tabla 6: Características de aislamiento acústico Table 6: Sound insulation characteristics
A partir de los resultados obtenidos, en la tabla 7 se establece una comparación con materiales de uso común en las construcciones a partir de sus valores de pérdida de transmisión para cada frecuencia. Based on the results obtained, a comparison is made in Table 7 with materials commonly used in constructions based on their transmission loss values for each frequency.
