Research group

Signal Processing Audio and Hearing Group

We research the processing, perception and control of complex signals.

Part of Engineering

About

We develop technological innovations related to both engineering and the human science aspects of acoustics.

Our main research areas are: 

  • active control of sound and vibration 
  • spatial and 3D audio reproduction and capture 
  • audiology, hearing impairment, psychoacoustics and communication 
  • signal processing for underwater acoustics 
  • bioacoustics 

Our work also extends beyond acoustics to: 

  • the fields of image processing 
  • biomedical signal processing 
  • human balance 

People, projects and publications

People

Professor David Simpson

Prof of Biomedical Signal Processing

Research interests

  • His research interests are in biomedical signal processing with applications in neurophysiology and cardio-vascular and cerebro-vascular control. Specific topics are:
  • Blood flow control in the brain (how does the brain regulate is own blood supply and how to detect impairment of this function).
  • Auditory evoked potentials (methods to detect the small electrical responses of the brain to auditory stimulation for the assessment of various hearing disorders).
