Research Group: ISVR Signal Processing and Control Group

The analysis of signals lies at the heart of studies in acoustics, dynamics, audiology and human sciences and as a basis for control of sound and vibration. The Group was formed as a focus for signal processing and control techniques and, as such, interacts with the other groups in ISVR. We are involved in a wide range of applications, from aircraft vibration, through active noise control and clinical patient monitoring, to the study of acoustic signalling of bats, dolphins and other marine mammals. Our extensive list of collaborators includes colleagues across the University (eg from Science and Engineering, Ocean Sciences, Medicine, Rehabilitation), local hospitals, and industry and academia at home and abroad. We run a number of short courses on signal processing techniques for industry and for clinical medicine.
