Eastern Branch Evening Meeting
More Mysteries Of Groundborne Noise And Vibration
A Presentation By Rupert Thornely-Taylor
Thursday 14 September 2017 at 7pm
The Board Room, Colchester Institute, Sheepen Road, Colchester, CO3 3LL


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 will continue from and bring up to date Rupert’s very well attended talk to our Branch last year, with more real-world examples to illustrate how the subject has moved on.   These examples highlight 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.

Attendance Certificates for CPD will be available.                                                                                    

There is no need to book a place at this event.  Please direct any queries to Hugo Cass, Secretary Eastern Branch. [Tel. 07970 807526, E-mail: info@ammonite-acoustics.co.uk ]

Colchester Institute’s Colchester Campus is within easy walking distance of both the railway station (Colchester Station) and the town centre. Walking from either location takes approximately 15 minutes.  The Meeting is being held in the Board Room, which is on the first floor, above the Institute’s Main Reception foyer.  The Board Room is directly opposite the first floor lifts.  The lifts are just to the right of the Reception Desk, as you enter the building.

Travelling by Car:

If travelling on the A12 via Chelmsford in a northerly direction, take the A133 exit sign-posted for Colchester Central. At the roundabout, take the second exit onto Cymbeline Way (The Avenue of Remembrance) and at the next roundabout take the third exit onto Westway. At the next roundabout, take the fourth exit into Sheepen Road and Colchester Institute is on the left, beyond the retail park (including Matalan). 

If travelling south from the Ipswich direction on the A12, take the A1232 Colchester exit.  Go straight over the next  two roundabouts and down Ipswich Road to a further roundabout. Take the third exit onto Cowdray Avenue.  Go through the traffic lights, over one roundabout and at the second roundabout take the first exit onto Westway.  At the next roundabout take the third exit onto Sheepen Road, as above.

Enter the campus via the Central Gate, then proceed to the Institute’s Main Reception.
