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...

Object-based reverberation for spatial audio (2017)
Journal Article
Coleman, P., Franck, A., Jackson, P., Hughes, R., Remaggi, L., & Melchior, F. (2017). Object-based reverberation for spatial audio. Journal of the Audio Engineering Society, 65(1/2), 66-77. https://doi.org/10.17743/jaes.2016.0059

Object-based audio is gaining momentum as a means for future audio content to be more immersive, interactive, and accessible. Recent standardization developments make recommendations for object formats; however, the capture, production, and reproduct... Read More about Object-based reverberation for spatial audio.

Characterization of acoustic diffusion using refracto-vibrometry (2016)
Journal Article
Jackett, R., Piper, B., & Hughes, R. (2017). Characterization of acoustic diffusion using refracto-vibrometry. Journal of Sound and Vibration, 392, 70-76. https://doi.org/10.1016/j.jsv.2016.12.028

Refracto-vibrometry is a relatively new measurement technique that is sensitive to variations in the optical refractive index of a medium caused by changes in acoustic pressure within that medium (the acousto-optic effect). It has so far been employe... Read More about Characterization of acoustic diffusion using refracto-vibrometry.

Evaluating a distortion-weighted glimpsing metric for predicting binaural speech intelligibility in rooms (2016)
Journal Article

A distortion-weighted glimpse proportion metric (BiDWGP) for predicting binaural speech intelligibility were evaluated in simulated anechoic and reverberant conditions, with and without a noise masker. The predictive performance of BiDWGP was compare... Read More about Evaluating a distortion-weighted glimpsing metric for predicting binaural speech intelligibility in rooms.

Volumetric diffusers : pseudorandom cylinder arrays on a periodic lattice (2010)
Journal Article
Hughes, R., Angus, J., Cox, T., Umnova, O., Gehring, G., Pogson, M., & Whittaker, D. (2010). Volumetric diffusers : pseudorandom cylinder arrays on a periodic lattice. ˜The œJournal of the Acoustical Society of America (Online), 128(5), 2847-2856. https://doi.org/10.1121/1.3493455

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
Pogson, M., Whittaker, D., Gehring, G., Cox, T., Hughes, R., & Angus, J. (2010). Diffusive benefits of cylinders in front of a Schroeder diffuser. ˜The œJournal of the Acoustical Society of America (Online), 128(3), 1149-1154. https://doi.org/10.1121/1.3463817

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...

The room-in-room effect and its influence on perceived room size in spatial audio reproduction
Presentation / Conference
Hughes, R., Cox, T., Shirley, B., & Power, P. The room-in-room effect and its influence on perceived room size in spatial audio reproduction. Presented at 141st Convention of the Audio Engineering Society, Los Angeles, USA

In spatial audio it can be desirable to give the impression of a target space (e.g. a church). Often the reproduction environment is assumed acoustically dead; in practice most listening spaces (e.g. domestic living rooms) introduce significant refle...
