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

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,... Read More about Microstructure influence on acoustical properties of multi-scale porous materials.

A relaxation approach for time domain modelling of sound propagation in porous media (2011)
Thesis

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... Read More about A relaxation approach for time domain modelling of sound propagation in porous media.
