Saving fuel by cutting noise
Engineering researcher Jordan Cheer has been honoured for his work to improve fuel efficiency in cars by reducing road noise.
His paper with Professor Stephen Elliott Spatial and temporal filtering for feedback control of road noise in a car was judged one of the best three out of 200 competing for the Sir James Lighthill Award at the 19 th International Congress on Sound and Vibration in Vilnius, Lithuania.
Jordan is reaching the end of his PhD at the University's Institute of Sound and Vibration Research (ISVR) and will then embark on postdoctoral work at ISVR. He is looking at ways to use the existing car loudspeakers to control interior noise. This would allow a reduction in the car's standard acoustic treatments and thus reduce weight and improve fuel efficiency.
