我们对人类对音频质量（尤其是高保真音乐信号）的感知感兴趣。总体感知质量至少部分取决于对较低级别的音色和空间属性（例如亮度，温暖度，位置和包围度）的感知。反过来，这些属性取决于声学参数，例如频谱和耳间互相关系数。通过结合声学测量和人类听力测试，我们正在探索声学参数与感知的音色和空间属性之间的联系，以及这些感知属性与整体质量和听众的偏好之间的联系。从我们的发现中，我们正在开发人类听觉感知的数学和计算模型，以及工程感知驱动的音频工具。
Since theInstitute of Sound Recording was created in 1998, it has become known internationally as a leading centre for research in psychoacoustic engineering, with world-class facilities and significant funding from research councils and industry. Our primary goal is simply this: to make sound better. Were interested in human perceptions of audio quality, particularly of high-fidelity music signals. Our work combines elements of acoustics, digital signal processing, psychoacoustics (theoretical and experimental), psychology, sound synthesis, software engineering, statistical analysis and user-interface design, with an understanding of the aesthetics of sound and music.<br><br>Our research aims to provide tools to assist in any area where assessment of the quality of audio as perceived by human listeners is desirable but, for one reason or another, potentially problematic, and to provide complementary tools to allow appropriate adjustment where the assessed quality is not as it should be. More generally, we aim to engineer perceptually-motivated signal analysis, processing and control systems. We have doubled the facilities space in the Department of Music and Media. Our Performing Arts Technology Studios have been upgraded and complemented by a 1.7m investment in state-of-the-art production and media suites.<br><br>Our Sound Recording PhD will prepare you for success at each stage of your project. The structure is designed to provide intensive graduate preparation for a future career and is suitable for either part-time or full-time candidates. You can also study for an MPhil with us, the differences between an MPhil and PhD is in the volume, originality and significance of the work you will do.<br><br>Youll begin your project with a thorough review of previously published academic literature in relevant areas, which will lead to a critical/analytical report. The conclusions to this report will suggest an appropriate next step, which will normally be some sort of experimental study, designed to test a hypothesis you have formulated from your literature review.
