TSA Technical Lecture - Acoustic Design and Changes to the National Building Code - May 25, 2017

The TSA Tech Lecture Series 2016 kicks off with a lecture from AECOM acoustic engineer Alan Oldfield. Acoustics and noise are top complaints for quality of life and the workplace; whereas good acoustic design can improve well-being and productivity. This seminar explores current trends in building design and what can go wrong when the acoustic environment is not considered in the design stage. Key concepts and factors of influence will be described, including airborne and impact (‘footfall’) sound transmission, reverberation, speech intelligibility and speech privacy. In Canada, building code requirements for sound control have until now been based on direct sound transmission through wall or floor elements. New requirements in the National Building Code introduce a more comprehensive approach, which also considers flanking sound transmission via indirect paths. This change in approach will be reviewed, along with examples to demonstrate how the new requirements can be fulfilled. The seminar will conclude with a discussion of further building code changes related to sound control that could be introduced in the future. Alan Oldfield, M.Eng., C.Eng. (UK), P.Eng., is a Senior Acoustic Engineer and Project Manager at AECOM and is a specialist in architectural acoustics and building engineering noise control. He has been an Acoustic Engineer at AECOM for 11 years. His work ranges from construction noise and vibration impact studies for infrastructure projects to architectural acoustic design for institutions and venues.
