Clarity : machine learning challenges to revolutionise hearing device processing
Presentation / Conference
Graetzer, S., Akeroyd, M., Barker, J., Cox, T., Culling, J., Naylor, G., …Viveros Munoz, R. Clarity : machine learning challenges to revolutionise hearing device processing. Presented at e-Forum Acusticum 2020, Online

In the Clarity project, we will run a series of machine learning challenges to revolutionise speech processing for hearing devices. Over five years, there will be three paired challenges. Each pair will consist of a competition focussed on hearing-de... Read More about Clarity : machine learning challenges to revolutionise hearing device processing.

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...

Measuring a portable audio device’s response to excessive sound levels
Report
Kendrick, P., Cox, T., Fazenda, B., & Jackson, I. Measuring a portable audio device’s response to excessive sound levels

This is a report detailing how a series of measurements were carried out to quantify the non-linear performance of a series of portable audio recorders. The performance of a series of common devices is quantified including the; Cannon 550D, Edirol r... Read More about Measuring a portable audio device’s response to excessive sound levels.

The 2nd Clarity Enhancement Challenge for Hearing Aid Speech Intelligibility Enhancement: Overview and Outcomes
Conference Proceeding
Akeroyd, M. A., Bailey, W., Barker, J., Cox, T. J., Culling, J. F., Graetzer, S., …Tu, Z. (2023). The 2nd Clarity Enhancement Challenge for Hearing Aid Speech Intelligibility Enhancement: Overview and Outcomes. . https://doi.org/10.1109/icassp49357.2023.10094918

This paper reports on the design and outcomes of the 2nd Clarity Enhancement Challenge (CEC2), a challenge for stimulating novel approaches to hearing-aid speech intelligibility enhancement. The challenge was for a listener attending to a target spea... Read More about The 2nd Clarity Enhancement Challenge for Hearing Aid Speech Intelligibility Enhancement: Overview and Outcomes.
