The improvement of acoustic performance construction systems is crucial. The flaws found
during the design of a building are often related to the lack of data that characterize the …

Resilient materials are nowadays widely used as underlayers in floating floors, in order to
reduce the transmitted impact sound pressure level. A floating floor, ie a floating slab on a …

Considerando o uso expressivo no cenário nacional de lajes pré-fabricadas de concreto
com elementos inertes de preenchimento do tipo cerâmico, este trabalho contém a …

During the last years it has been observed a growing interest in the characterization of the
acoustical performances of building elements at low frequencies. The proposal to extend …

The use of simplified prediction models described in the EN 12354 series standard is largely
diffused and suggested or adopted in many building codes. The aim of this work is to …

The estimation of acoustical performance of horizontal partitions from the performance of
elements and components using EN 12354 Standard do not actually provides satisfactory …

Hollow brick and concrete-slab floors can reach high acoustic performances with floating
floor over a resilient layer. However in situ acoustic performances may vary significantly …

The ability to estimate the impact sound insulation between rooms on the basis of product
performance, as stated in EN 12354-2 [1] Standard, is certainly of great interest. The …

Neste trabalho são apresentadas as características de isolamento acústico para os sons
aéreos e de impacto de três tipos de lajes, sendo lajes nervuradas de duas espessuras, tipo …

The prediction models proposed by the standards of the EN ISO 12354 series represent the
reference point for the evaluation of the acoustic performance of buildings. However, there …
