Timber usage in the Australian construction industry has significantly increased due to its
strength, aesthetic properties and extended allowances recently introduced in building …

This article presents a perceptual comparison of the loudness of a large range of 64 different
typical “living room” sounds transmitted through two different walls:(1) a light-weight wall …

This paper introduces a methodology that makes use of laser Doppler vibrometry to assess
the acoustic insulation performance of a building element. The sound power radiated by the …

Steel studs are an inevitable part of drywall construction as they are lightweight and offer the
required structural stability. However, the studs act as sound bridges between the …

The paper presents the application of Artificial Neural Networks (ANN) in predicting sound
insulation through multi-layered sandwich gypsum partition panels. The objective of the …

The irrotational part of the structural intensity for flexural wave motion in plate-like structures
is calculated from measurement data of kinematic quantities, such as out-of-plane velocities …

Featured Application The work presented in the paper, relates to building physics,
specifically to building acoustics. Results can be applied in engineering practice and …

Gypsum board walls are widely used in today's buildings. A possible way to considerably
increase the sound insulation performances of such lightweight walls is to apply double …

In this paper, a wave based model is developed for the investigation of the direct sound
transmission through double walls with structural connections placed between two rooms …

In this paper we discuss the airborne sound insulation of timber frame partition walls with
different construction details measured in the laboratory according to EN ISO 10140-2. The …
