Sound and thermal insulating properties of materials on mineral bases

Abstract

Results of the thermal and acoustic testing of selected mineral based materials used in building construction are presented. The sound absorption and reflection coefficient of the normal incidence sound wave on tested materials in the frequency range of 50 - 6500 Hz and thermal conductivity coefficient were determined. Obtained results were confronted with the theoretical numerical prediction models based on FEM BEM methods as obtained from the SAMCEF software. Obtained results allow optimization of the wall structure construction for household and building industry applications.© (2006) by the International Institute of Acoustics & Vibration.
