Analysis of airborne sound reduction index of bare CLT walls

2018
Estimation of the airborne insulation of vertical partitions, evaluated from the performance of basic components according to standardized prediction models, does not provide satisfactory results when applied to walls made of Cross-Laminated Timber (CLT) elements.

COMPARISON BETWEEN LABORATORY AND IN SITU SOUND REDUCTION INDEX MEASUREMENTS

2001
The paper deals with the results of research concerning the acoustical properties of masonry walls tested both in a laboratory with suppressed flanking transmission and in a laboratory with relevant flanking transmission (in situ). Measurements were aimed at evaluating the difference between Sound Reduction Index in laboratory and in situ and the ...

On the uncertainty of sound reduction index measurements from inter-laboratory tests

2018
Test reports of building acoustics measurements cannot be considered complete without declaring the associated uncertainty. Two dominant methods exist for calculating the uncertainty, i.e. the empirical approach, standardized in ISO 5725, and the modelling approach, standardized in ISO/IEC Guide 98-3.

SOUND REDUCTION INDEX OF CARDBOARD PANELS FEATURING A HONEYCOMB PAPER CORE [PDF]

Nowadays it is crucial to design environmentally friendly solutions exploiting recycled materials. From this point of view, paper and cardboard can be easily recovered and are largely available in dump sites. From an acoustic point of view, such materials are usually lightweight and do not possess structural properties.
