Qualitative evaluation of media device orchestration for immersive spatial audio reproduction (2018)
Journal Article

The challenge of installing and setting up dedicated spatial audio systems can make it difficult to deliver immersive listening experiences to the general public. However, the proliferation of smart mobile devices and the rise of the Internet of Thin...

Speech-to-screen : spatial separation of dialogue from noise towards improved speech intelligibility for the small screen (2018)
Presentation / Conference
Demonte, P., Tang, Y., Hughes, R., Cox, T., Fazenda, B., & Shirley, B. (2018, May). Speech-to-screen : spatial separation of dialogue from noise towards improved speech intelligibility for the small screen. Presented at 144th International Pro Audio Convention (AES Milan 2018), Milan, Italy

Can externalizing dialogue when in the presence of stereo background noise improve speech intelligibility? This has been investigated for audio over headphones using head-tracking in order to explore potential future developments for small-screen dev...

Volume diffusers for architectural acoustics (2011)
Thesis
Hughes, R. Volume diffusers for architectural acoustics. (Thesis). University of Salford

Most conventional diffusers are used on room surfaces, and consequently can only operate on a hemispherical area. Placing a diffuser in the volume of a room may provide greater efficiency by allowing scattering into the whole space. There are very fe...

Most conventional diffusers take the form of a surface based treatment, and as a result can only operate in hemispherical space. Placing a diffuser in the volume of a room might provide greater efficiency by allowing scattering into the whole space....

Diffusive benefits of cylinders in front of a Schroeder diffuser (2010)
Journal Article

A numerical investigation is performed into the diffusive effects of cylinders positioned in front of a Schroeder diffuser. A regular line of cylinders is shown to offer notable improvements to diffusion from a periodic Schroeder device, provided lat...

Multiple scattering between cylinders and a schroeder diffuser (2010)
Journal Article
Pogson, M., Whittaker, D., Gehring, G., Hughes, R., Angus, J., & Cox, T. (2010). Multiple scattering between cylinders and a schroeder diffuser. Acta acustica united with Acustica, 96(2), 292-299. https://doi.org/10.3813/AAA.918278

A multiple scattering method is developed to model an array of N cylinders positioned in front of a Schroeder diffuser. Results are compared against the more computationally intensive boundary element method, as well as existing multiple scattering m...
