Modeling walking on a lightweight wooden floor
(2015) 44th International Congress and Exposition on Noise Control Engineering, INTER-NOISE 2015 p.6263-6270- Abstract
The most common sound insulation problem for lightweight timber structures is impact sounds from people walking. This is especially apparent in the low frequency range, due to differences in weight, stiffness, density and repartitioning as compared to more traditional materials. As lightweight timber structures increase their market share, the understanding of their behaviour and the ability to predict the production and spread of these impact sounds by numerical models during the design phase of a building, become more important. The subject of this paper is a typical wooden floor constructed from particleboards on top of wooden beams. The floor is subjected to loads from test subjects walking on the floor.

The most common sound insulation problem for lightweight timber structures is impact sounds from people walking. This is especially apparent in the low frequency range, due to differences in weight, stiffness, density and repartitioning as compared to more traditional materials. As lightweight timber structures increase their market share, the understanding of their behaviour and the ability to predict the production and spread of these impact sounds by numerical models during the design phase of a building, become more important. The subject of this paper is a typical wooden floor constructed from particleboards on top of wooden beams. The floor is subjected to loads from test subjects walking on the floor. We compare measurements on this floor with simulations of the same floor construct using a finite element model with idealised walking loads. The frequency range of interest here is from 20Hz to 200Hz. The aim of the comparison is to create an accurate model of the floor that can capture the behaviour of the real structure and that can be used in subsequent models of larger structures i.e. multi-storey wooden buildings.
