Acoustical properties of double porosity granular materials (2011)
Journal Article
Venegas, R., & Umnova, O. (2011). Acoustical properties of double porosity granular materials. ˜The œJournal of the Acoustical Society of America (Online), 130(5), 2765-2776. https://doi.org/10.1121/1.3644915

Granular materials have been conventionally used for acoustic treatment due to their sound absorptive and sound insulating properties. An emerging field is the study of the acoustical properties of multiscale porous materials. An example of these i... Read More about Acoustical properties of double porosity granular materials.

Microstructure influence on acoustical properties of multi-scale porous materials (2011)
Thesis
Venegas Castillo, R. Microstructure influence on acoustical properties of multi-scale porous materials. (Thesis). Salford : University of Salford

This thesis investigates the microstructure influence on the acoustical properties of multi-scale porous materials. The theory of sound propagation in multi-scale materials is extended to account for physical processes specific to very small pores,...

A relaxation approach for time domain modelling of sound propagation in porous media (2011)
Thesis
Turo, D. A relaxation approach for time domain modelling of sound propagation in porous media. (Thesis). Salford : University of Salford

In the present study a relaxation approach to modelling sound propagation in porous media has been developed. A frequency domain model has been formulated and is shown to allow an analytical transformation of the governing equat...
