An experimental and statistical study of the behavior of the vibration field in two coupled lightweight wooden joist floors

Authors: Lars-Göran Sjökvist, Jonas Brunskog

Abstract:
The aim of this study was to evaluate the vibration level attenuation of a common wooden floor structure and to present the results together with the statistical precision of the evaluation. Linear regression was used to determine the attenuation rate in the two main directions of the floor structure. The probability for the attenuation rate to be zero was calculated. The attenuation rate was found to be high in the direction perpendicular to the beams with a probability to be zero lower than 0.001. In the direction parallel to the beams the attenuation rate was found to be close to zero.
