Research Group: Acoustics Group

Currently Active: 

We undertake projects ranging from fundamental science to real-world applications and are active in three major areas: aeroacoustics of aircraft engines; ultrasonics and underwater acoustics; and noise source imaging and virtual acoustics. The Group includes the Rolls-Royce University Technology Centre in Propulsion Systems Noise .

Ultrasonic and underwater acoustics

Sound travels better in water than any other form of signal, and research in the Centre for Ultrasonics and Underwater Acoustics (UAUA) brings together acousticians, oceanographers, archaeologists, zoologists, geophysical surveyors and chemists, who explore questions such as:

  • What would a waterfall sound like on Titan, Saturn's largest moon? How could this have enhanced the Cassini-Huygens probe mission?
  • How do dolphins think and how can this be exploited to protect shipping?
  • Can we produce 3D pictures of shipwrecks, hidden for hundreds fof years under the mud at the bottom of the sea? Can we undertake archaeology without disturbing the wreck?
  • Do humpback whales create 'walls of sound' to trap prey and how can we exploit this phenomenon to protect seals from the noise of piling in harbours?
  • How can we use sound to monitor the annual transfer of billions of tonnes of atmospheric gases into the ocean and back again – a process of key importance to our climate and its stability?

The themes of exploration and discovery underpin UAUA's research, and key activities range from climate studies to the protection of marine mammals. Using an interdisciplinary approach, UAUA takes projects from fundamental science to real-world applications.

Biomedical and high-power ultrasonics

In addition to our oceanographic activities, we conduct research which addresses a range of biomedical issues, such as how ultrasound can be exploited to change chemical reactions and therefore help industries become cleaner and more efficient.

Our research has led to developments in many areas, including:

  • a 'smart stethoscope' to assess the effectiveness of ultrasound in destroying kidney stones
  • an ultrasound system to detect osteoporosis and the general health of bone
  • a method for assessing muscle quality using ultrasound
  • techniques that enable industry to assess the effectiveness of ultrasonic devices designed
    to clean surgical instruments, circuit boards and other tools
  • techniques to detect erosion in pipelines
  • a discovery that could help electroplating  companies become cleaner and more efficient through the use of acoustics.

We have also contributed to a national study looking at the use of ultrasound to treat tumours and have advised on the safe use of ultrasound (eg for foetal scanning). These studies are carried out in collaboration with a range of hospitals, including Guy's and St Thomas', London; the Institute of Cancer Research; Churchill Hospital, Oxford; Southampton General Hospital; and Chemistry at the University of Southampton.

Aeroacoustics and nonlinear acoustics

Aeroacoustics is the study of aerodynamically generated sound. The Acoustics Group supports a substantial programme of research in aeroacoustics which focuses on reducing aircraft noise. This is a particularly challenging problem since aircraft noise is generated by multiple sources, many of which are associated with turbulent, unsteady motion. All must be reduced to achieve a significant reduction in overall noise. Aircraft noise is a major nuisance for residents who live close to airports, and a significant environmental constraint on the growth of commercial aviation. Our Group is home to the Rolls-Royce University Technology Centre (UTC) in Gas Turbine Noise which forms part of the global Rolls-Royce research network and undertakes research on all aspects of aircraft noise. The activities of the UTC include theoretical, computational and experimental studies of aircraft noise sources and the development of robust noise prediction tools. Areas of particular interest are the design of acoustic liners to reduce noise radiated from intake and bypass ducts, the development of improved models for fan broadband noise and jet noise, and their integration within whole aircraft noise prediction schemes. We are also responsible for developing and exploiting advanced measurement techniques for rig and full-scale engine noise tests, and for appraising noise data acquired in industrial test facilities by Rolls-Royce and other industrial partners.
