I am a PhD student exploring the topic of The Quality of Experience of 3D Audio under the supervision of David Kirk. This research project, which commenced in October 2014, is a collaboration between BBC Research and Development and Open Lab at Newcastle University. Much work is being carried out on improving the technical aspects of 3D audio reproduction (such as binaural and ambisonics) and it is likely that such technologies and related content will be more widely available to the user in the coming years. However, it is not yet understood how the user perceives such technologies and what aspects of the reproduction give a good or bad quality of experience. How does the quality of experience vary across the range of consumer devices, across the different 3D audio techniques and across different content genres? This project considers questions like this and aims to develop experimental techniques for measuring the quality of experience of 3D audio.

Prior to this project I lived in Denmark for two years whilst studying for a master’s degree in Acoustic Engineering at the Technical University of Denmark, Copenhagen. This degree gave me a broad knowledge of acoustics including loudspeaker and microphone design, room acoustics and hearing science. My thesis was on Near-Field Reconstruction of Sound Fields Using a Rigid-Sphere Microphone Array and investigated a new method of predicting and visualising sound fields for use in noise identification. My bachelor degree is in Physics with Music Technology from Keele University and whilst there I undertook an exchange semester at Dalhousie University, Canada.
