Lattice metamaterials as advanced airborne sound insulators

Physical Review Applied
. Airborne sound insulation is vital for noise reduction across various engineering fields. Traditional mass-based soundproofing methods, while effective, are often hindered by their bulkiness and limited ventilation capability. In contrast, lattice metamaterials provide a lightweight architected alternative with high tunability ...

Game engine based auralization of airborne sound insulation

, 2018
Describing planned acoustic design by single number ratings yields a weak link to the subjective event, especially when the single number ratings are interpreted by others than experienced acousticians.

Calculation of airborne and impact sound insulation between dwellings

, 1986
Some years ago a model was described for the calculation of the weighted airborne sound insulation between dwellings. Further work has been done since in order to increase the applicability of this model, including the extension to octave band ...

A Design Methodology Incorporating a Sound Insulation Prediction Model, Life Cycle Assessment (LCA), and Thermal Insulation: A Comparative Study of Various Cross-Laminated Timber (CLT) and Ribbed CLT-Based Floor Assemblies

Acoustics
Mass timber is increasingly being employed in constructing low- and mid-rise buildings. One of the primary reasons for using mass timber structures is their sustainability and ability to reduce environmental consequences in the building sector.
