JORDAN CHEER: Active Approaches to Enhancing Noise and Vibration Control

Jordan Cheer is a Professor at the Institute of Sound and Vibration Research, University of Southampton and Royal Academy of Engineering Research Chair in Smart Acoustic Control Technologies. Jordan graduated from the University of Surrey in 2008 with a BMus (Tonmeister) in Music and Sound Recording, in 2009 he received an MSc in Sound and Vibration from the ISVR and received the PhD in 2012 from the same institute. His research is mainly focused on active acoustic technologies, with an emphasis on the control and manipulation of sound and vibration. This encompasses the active control of noise and vibration, and the detection, enhancement and control of sound. His research has been published widely, with more than 150 publications to-date. Jordan serves as a Subject Editor for the Journal of Sound and Vibration and an Associate Editor for the Journal of the Acoustical Society of America. He is a Chartered Engineer and a Fellow of the Institute of Acoustics.

KEYNOTE SUMMARY

There is a continuously evolving need for noise and vibration control treatments that offer high levels of performance within lightweight and compact design constraints. Active noise and vibration control technologies are now relatively mature within the automotive sector, but their application remains constrained to specific challenges due to their relatively high cost. This talk will review the development of active noise and vibration control systems for automotive applications, before discussing emerging methods that synergistically combine active control with emerging passive NVH treatments. These smart acoustic control technologies variously demonstrate the potential for reduced energy requirements and lower computational burden compared to purely active control systems, whilst highlighting the higher levels of control performance, increased control bandwidth, adaptability and improved robustness compared to passive systems.
