Acoustic metamaterials comprised of dead-end pores and black hole effect for low frequency sound absorption in linear and nonlinear regimes (2021)
Thesis
Brooke, D. Acoustic metamaterials comprised of dead-end pores and black hole effect for low frequency sound absorption in linear and nonlinear regimes. (Thesis). University of Salford

The aim of this work is to design and test acoustic metamaterial absorbers particularly for mitigation of
low frequency sound of high intensity. The absorbers designed are formed of a series of plates with a
central perforation, separated by air... Read More about Acoustic metamaterials comprised of dead-end pores and black hole effect for low frequency sound absorption in linear and nonlinear regimes.

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