The Mysteries of Groundborne Noise & AGM

Winchester Guildhall, The Broadway, Winchester, SO23 9GH


The Southern Branch of the IOA invites you to share an evening with Rupert Thornley-Taylor, who will talk to us about “The mysteries of groundborne noise”. An interesting one not to be missed!

“It would take several bookcases to contain all the textbooks on airborne acoustics and noise. One shelf would do for all the books on groundborne noise and vibration. It is acoustics, but not as we know it. Measurement of vibration may seem simple, but a measurement is only of use if it can be applied correctly to the purpose for which it is made.

When groundborne noise makes the last stage of its journey it becomes airborne sound, but usually it is of interest in rooms, and at low frequencies where diffuse-field room acoustics does not apply and wave acoustics must be used instead. 

This talk highlights fundamental issues such as choice of measurement location, the way of attaching the transducers to the medium, errors and uncertainty in the results, prediction of vibration levels in nearby structures, and effects of the vibration on a receptor, such as a human being or a sensitive item of equipment.”

The presentation will be followed by the Southern Branch’s AGM, where all corporate members are welcome to vote. There will also be a Q&A afterwards at a local curry house with the presenter.

The event is free to members of the IoA, as well as to students and the general public. As numbers are limited, in order to register for this event, please go to the registration page at:
