Abstract
Lightweight structures made of timber material have a number of advantages; they may become cost effective in the future and they demand relatively short production duration. However, one of the main drawbacks is related to the sound transmission, as it is becoming an increasing nuisance. The differences in weight, stiffness, density and repartition compared to traditional materials have repercussions on how the sound propagates through the structures and problems of sound insulation in the low frequency range through the junctions may arise. This paper provides an investigation of the reflection and transmission properties of a wall-floor real-sized timber element, which resembles a section of a lightweight building. The latter... (More)
Lightweight structures made of timber material have a number of advantages; they may become cost effective in the future and they demand relatively short production duration. However, one of the main drawbacks is related to the sound transmission, as it is becoming an increasing nuisance. The differences in weight, stiffness, density and repartition compared to traditional materials have repercussions on how the sound propagates through the structures and problems of sound insulation in the low frequency range through the junctions may arise. This paper provides an investigation of the reflection and transmission properties of a wall-floor real-sized timber element, which resembles a section of a lightweight building. The latter investigation was carried out by comparing finite element simulations with experimental data. The fairly good match between the experimental results and the simulations point out at the applicability of the finite element analysis as a prediction tool during the design phase before buildings are actually put up in order to prevent future problems.
