Estimating BS 4142 Character Corrections at the Planning Stage
A presentation by Matt Torjussen, followed by an opportunity for Q&A and informal chat.
BS 4142 provides subjective and objective methods for determining graded corrections to the specific sound level for impulsivity and tonality; however, these require specific sound sources to be installed and operating. In planning applications where the sources are proposed, or the propagation path is intended to change significantly, only the professional judgement of the acoustics practitioner can be relied upon to determine the likely prominence/audibility of these features at a remote assessment location. To address this gap, simplified auralisation (‘auralisation-lite’) has been used to estimate the character corrections using the calculation method from ISO 9613-2.
In this talk, the problem being addressed will be highlighted, the process of auralisation-lite will be described, the results of experiments testing the method will be presented, and an interactive test will be used to highlight the importance of objective methods.
Matt Torjussen is the Acoustics Lead at ANV Measurement Systems. He is a graduate of the ISVR in Southampton, a Chartered Engineer, and a member of the Institute of Acoustics. Matt has experience in consultancy, product design, and instrumentation.
His research interests include understanding the acoustic features in environmental noise and their effects on human perception, as well as the creation of tools for measuring, evaluating, and assessing them.
How to get there
Arup, 7th Floor, 1 W Regent St, Glasgow G2 1RW
Attendees should be aware that the office is in the Glasgow City Low Emission Zone (LEZ) and that there are therefore charges for certain vehicles (for practical purposes, it is generally the case that diesel engine vehicles registered after September 2015, and petrol vehicles registered from 2006 onwards will meet the required LEZ standards). The closest multi-storey carpark is the NCP at 81 Mitchell St, Glasgow G1 3LN. On-street parking is available in the surrounding area but is limited and may require the Ringo App to pay. The office is a 5 minutes’ walk from both Glasgow Central and Glasgow Queen Street and is close to many bus stops.
If you have any queries about this meeting, please contact Laurent Galbrun (Heriot-Watt University) L.G.U.Galbrun@hw.ac.uk.
