Dual frequency band amplitude panning for multichannel audio systems
Presentation / Conference
Hughes, R., Franck, A., Cox, T., Shirley, B., & Fazi, F. Dual frequency band amplitude panning for multichannel audio systems. Presented at 2018 AES International Conference on Spatial Reproduction - Aesthetics and Science, Tokyo, Japan

Panning laws for multi-loudspeaker setups, for example vector base amplitude panning, are typically derived based
on either low or high frequency assumptions. It is well known, however, that auditory cues for both localization and loudness differ at... Read More about Dual frequency band amplitude panning for multichannel audio systems.

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...

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.

Determining and labeling the preference dimensions of spatial audio replay
Presentation / Conference
Francombe, J., Brookes, T., Mason, R., & Woodcock, J. Determining and labeling the preference dimensions of spatial audio replay. Presented at QoMEX 2016, Lisbon, Portugal

There are many spatial audio reproduction systems currently in domestic use (e.g. mono, stereo, surround sound, sound bars, and headphones). In an experiment, pairwise pref-erence magnitude ratings for a range of such systems were collected from trai...

A high-frequency BEM for 3D acoustic scattering
Presentation / Conference
Hargreaves, J., Lam, Y., Langdon, S., & Hewitt, D. A high-frequency BEM for 3D acoustic scattering. Presented at 22nd International Congress on Sound and Vibration, Florence. Italy

The Boundary Element Method (BEM) is a powerful method for simulating scattering of acoustic waves which has many advantages, particularly when the problem concerns an object in an unbounded medium. Its applications are however limited in practice be... Read More about A high-frequency BEM for 3D acoustic scattering.

Acoustic cross-energy measures and their applications
Presentation / Conference
Hargreaves, J., & Lam, Y. Acoustic cross-energy measures and their applications. Presented at The 22nd International Congress on Sound and Vibration, Florence. Italy

Acoustic energy density and acoustic intensity are quantities which are well established and widely applied. When these are applied to pressure and particle-velocity fields which are the linear superposition of more than one wave they naturally separ...

Fault tolerant strategy of actuator failure for actively controlled railway wheelsets
Presentation / Conference
Mirzapour, M., Mei, T., & Li, H. Fault tolerant strategy of actuator failure for actively controlled railway wheelsets. Presented at 2014 UKACC International Conference on Control, Loughborough University

This paper presents the development of a fault-tolerant scheme through an analytical redundancy approach for actively controlled railway wheelsets. The main aim of the study is to maintain the basic control of the rail vehicles in the event of actuat...

Towards a full-bandwidth numerical acoustic model
Presentation / Conference
Hargreaves, J., & Lam, Y. Towards a full-bandwidth numerical acoustic model. Presented at Forum Acusticum, Krakow, Poland

Prediction models are at the heart of modern acoustic engineering and are used in a diverse range of applications from refining the acoustic design of classrooms and concert halls to predicting how noise exposure varies through an urban environment....
