“…To examine the effect of the concrete core fill on the floorfloor flanking path, the vibration reduction index of the path in question was examined with and without the core fill using the finite element method (FEM). FEM can predict vibration transmission between concrete structures with sufficient accuracy [2], and it has been previously used for investigating the vibration reduction index of building junctions [2][3][4][5][6]. Additionally, FEM allows the complex geometry of the hollow core slabs and the core fill to be taken into account accurately.…”

“…Resilient joints between building constructions reduce vibration transmission from one element to another [4]. Because of that, it is a frequent impression among building engineers that resilient joints in any position close to the joint positively affect the sound insulation between two rooms.…”

“… La ejecución influencia los resultados de aislamiento acústico y posiblemente también los resultados del índice K ij . Por ejemplo, las fisuras en las uniones entre elementos constructivos o en las propias particiones, afectan a los índices K ij [97] y no están recogidas en el modelo de cálculo.…”

“…Figura 12.2, los valores calculados son menores que los valores resultantes de los ensayos. Esto también ha sido descrito por otros autores como Crispin, et al [78,97]. Se observa un incremento del índice K ij a partir de 400 Hz de 4,5 dB/octava en este caso.…”

“…Por otro lado, a pesar de lo que dice la teoría, se observa en las figuras 12.2, 12.3 y 12.4 la tendencia a un aumento del K ij a partir de 500 Hz, con una pendiente media de 2,5 dB/octava. Comparando con mediciones experimentales publicadas, como las de Crispin et al [78,97] y Schiavi y Astolfi [77], también pueden observarse estas variaciones, aunque ningún autor especifica claramente el motivo de que se producen.…”

This research work deals with the effects of junction construction details on airborne sound insulation in buildings and the analysis of flanking transmissions across double ceramic brick walls with elastic interlayers.The sound transmission between two adjacent rooms comprises two paths: the direct path, caused by the incident sound on a separating wall, and the indirect path, through flanking elements connected to the separating wall, such as floors, internal walls, ceilings, etc. Flanking elements vibrate when excited in the sound field, thus transferring sound via structure borne to the receiving room. Dominant flanking transmissions can decrease the field sound insulation performance of the building.The vibration reduction index, K ij. expresses the acoustic attenuation of construction joints. This is an input parameter in the calculation models designed to estimate the airborne sound insulation between adjoining rooms in buildings. These models are used to comply with the acoustic requirements set by "Basic Document DB HR Protection against noise" included in the "Spanish Building Code". The characterization of K ij. must be addressed experimentally by means of measurements. The available empirical K ij. formulae were developed in different European laboratories, but they have not been validated with standard tests performed on common Spanish walls, such as those studied in this work.
