EXPERIMENTAL STUDY ON AIRBORNE SOUND INSULATION OF CROSS LAMINATED TIMBER PANEL WALLS

Analysis of acoustical behavior of bare cross laminated timber floors for the evaluation of the improvement of impact sound insulation

The estimation of impact sound insulation of horizontal partitions, evaluated from the performance of basic components using EN 12354-2 Standard, do not actually provides satisfactory results when applied to the floors realized with cross laminated timber (CLT) elements. Among the possible reasons of this limited correspondence between predicted and measured impact noise values, one of the most...

Sound insulation in multi-story timber buildings

During on an extensive investigation of a multi-story timber building with light-frame construction, several stages of the building process and their impact on sound transmission were observed. The sound insulation properties of the building components were measured before and while the buildings were occupied. Furthermore, interviews with the occupants were conducted. This procedure made it po...

Predicting the Sound Insulation of Walls

Between 1990 and 1998, the author published five conference papers which described the gradual development of a simple theoretical model for predicting the sound insulation of building partitions. The first aim was to extend Sharp’s model for cavity walls to cavities without sound absorption. The second aim was to remove the reported over prediction of Sharp’s model for cavity walls. The third ...

Ambient vibration tests of a cross-laminated timber building

a study on insurer solvency by panel data model: the case of iranian insurance market

the aim of this thesis is an approach for assessing insurer’s solvency for iranian insurance companies. we use of economic data with both time series and cross-sectional variation, thus by using the panel data model will survey the insurer solvency.
