Railways are an environmentally friendly means of transport but noise and vibration are increasingly becoming a source of objection to new developments and existing operations, Crossrail and HS2 being two recent high-profile examples.
What are the sources of noise and vibration and their physical mechanisms? How are these sounds and vibrations generated and how do they propagate into the environment? What are the prospects for reducing them? From rolling noise, to curve squeal, aerodynamic noise and ground-borne noise and vibration, all sources have different characteristics and influencing factors.
David will also discuss the current legislative framework, including noise limits for new vehicles in the Technical Specifications for Interoperability, and ongoing research.
PROFESSOR OF RAILWAY NOISE AND VIBRATION, INSTITUTE OF SOUND AND VIBRATION RESEARCH, UNIVERSITY OF SOUTHAMPTON
David has spent 30 years studying noise and vibration from railways. He has written over 100 journal papers and his book, Railway Noise and Vibration: Mechanisms, Modelling and Means of Control, was published in 2008.
David studied mathematics at Cambridge and has a PhD from Southampton. He previously worked at BR Research and TNO in the Netherlands before joining ISVR in 1996.
