The effect of stereo crosstalk on intelligibility : comparison of a phantom stereo image and a central loudspeaker source (2007)
Journal Article
Shirley, B., Kendrick, P., & Churchill, C. (2007). The effect of stereo crosstalk on intelligibility : comparison of a phantom stereo image and a central loudspeaker source. Journal of the Audio Engineering Society, 55(10), 852-863

The roll out of surround sound for broadcasting and packaged media, and the consequent addition of a center loudspeaker for sound accompanying video have the potential to reduce the impact of acoustical crosstalk and so improve the intelligibility of...

Up-mixing and localisation-localisation performance of up-mixed consumer multichannel formats
Presentation / Conference
Chaffey, R., & Shirley, B. Up-mixing and localisation-localisation performance of up-mixed consumer multichannel formats. Presented at 122nd AES Convention, Vienna, Austria

A number of listening tests were carried out to assess localisation of sound in derived surround sound fields. Two up-mixed consumer multichannel formats that use matrix decoding of 3/2 multichannel surround channels to increase the surround channel...

This thesis investigates how developments in audio for digital television can be utilised to improve the experience of hearing impaired people when watching television. The work has had significant impact on international digital TV broadcast standar... Read More about Improving television sound for people with hearing impairments.

The effect of early impulse response length and visual environment on externalization of binaural virtual sources
Presentation / Conference
Sinker, J., & Shirley, B. The effect of early impulse response length and visual environment on externalization of binaural virtual sources. Presented at 140th AES Convention, Paris, France

When designing an audio-augmented-reality (AAR) system capable of rendering acoustic “overlays” to real environments, it is advantageous to create externalized virtual sources with minimal computational complexity. This paper describes experiments de... Read More about The effect of early impulse response length and visual environment on externalization of binaural virtual sources.

Television dialogue; balancing audibility, attention and accessibility
Presentation / Conference
Ward, L., & Shirley, B. Television dialogue; balancing audibility, attention and accessibility. Presented at Conference on Accessibility in Film, Television and Interactive Media, Department of Theatre, Film and Television, University of York, United Kingdom

Sound effects and other non-speech broadcast elements play many roles within television and radio content, including
progressing the narrative. However, accessibility strategies for hard of hearing listeners tend to reduce all non-speech
elements e... Read More about Television dialogue; balancing audibility, attention and accessibility.

R2SPIN : re-recording the Revised Speech Perception in Noise Test
Presentation / Conference
Ward, L., Robinson, C., Paradis, M., Tucker, K., & Shirley, B. R2SPIN : re-recording the Revised Speech Perception in Noise Test. Presented at 20th Annual Conference of the International Speech Communication Association

Speech in noise tests are an important clinical and research toolfor understanding speech perception in realistic, adverse listen-ing conditions. Though relatively simple to implement, theirdevelopment is time and resource intensive. As a result,... Read More about R2SPIN : re-recording the Revised Speech Perception in Noise Test.

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...
