The more severe acoustic requirements imposed by the new Belgian standard for dwellings are a real challenge for the building professionals (architects, contractors, building elements manufacturers and suppliers, etc) and more particularly for the market of lightweight materials. An important brick producer in partnership with the BBRI has succeeded to propose efficient acoustic solutions for these kinds of materials by treating in particular the flanking transmission. Indeed, to obtain high sound insulations, the structural transmission paths of noise through the flanking walls cannot be neglected any more. By the application of resilient rubber interlayers at the junctions, these transmission paths are nearly eliminated. A large number of measurements was carried out in order to study in detail the effect of these flexible joints on the sound transmission. These measurements were made in a specially designed laboratory where vibration reduction indexes can be measured for all types of connections and for different loads. We present, in this paper, the measurement survey and the analysis of the results.

“…, 2007 a, se muestra un estudio donde la misma solución constructiva para aislamiento acústico, tiene diferentes resultados de medición, debido a las diferentes condiciones de los flancos laterales. Se pueden encontrar diferentes trabajos sobre estudios de las transmisiones laterales, como son Craik y Osipov, 1995, Hopkins, 1999, Crispin al., 2006y Alba et al, 2008. En estos trabajos y en las normas ISO 10848 (2007) se puede comprobar lo complejo de estos ensayos, que en algunos casos pueden durar varios días.…”

En este trabajo se plantea el uso del método de los elementos finitos para el estudio de las transmisiones laterales a través del índice de reducción de vibraciones, para el caso de soluciones constructivas con suelos flotantes. Por una parte, la inserción de láminas elásticas en nuevas soluciones constructivas es en la actualidad una práctica muy común. Por otra parte, los procedimientos de ensayo para el estudio acústico de este conjunto (forjado con lámina elástica) son muy laboriosos y las ecuaciones empíricas existentes no satisfacen la realidad en muchos de los casos. Es por este motivo que se plantea el estudio mediante los elementos finitos, lo que nos permitirá dar solución numérica a un gran conjunto de diferentes soluciones constructivas y poder así mejorar las predicciones numéricas para el aislamiento acústico.

“…It is found that the sound transfer coefficient through a junction will be evidently attenuated by adding the resilient layer [2]. The bending wave model of Craik [3] was developed to predict the effect of the resilient layers. The impact sound through a floating floor at low frequencies was developed by Tongjun Cho [4].…”

Abstract. Due to favorable sound isolation to the impact sound transmission, People are prone to adopt floating floor as insulation structure. Of the researches on impact sound insulation through a floating floor, the theoretical study is much less than the experiment analysis. For the purpose to determine sound insulation and the dominate sound transmission path through a floating floor, the Statistical Energy Analysis(SEA) is employed to set up a theoretical model for predicting sound transmission across two floor plates connected by a resilient interlayer, and there are two main paths: the stud path and the cavity path. It reveals that the resilient interlayer plays a key role in impact sound insulation of a floating floor, and there exists a good agreement between predicted and measured sound pressure level (SPL) in the rooms below the floors.
