About the presenters:
Clair Wakefield is a professional engineer with a lifetime of experience in acoustics. Clair obtained his Bachelor and Masters of Applied Science degrees in mechanical engineering from UBC. He is the principal of Wakefield Acoustics Ltd. a local engineering firm specializing in Architectural Acoustics and Building Noise Control. They also consult for public sector transportation projects including highway and airport noise impact assessment.
Duane Marriner earned his honours physics degree from UVic and a Masters of Applied Science in mechanical engineering from UBC. In the pursuit of their professional services they have measured numerous transportation noise sources and provided solutions using sophisticated modelling software.
They have presented papers on topics of their expertise including Noise and Annoyance, Quiet Pavement and Environmental Noise Mapping.
About the Topic:
Since its inception in 1988, the BCBEC has been a forum for the exchange and dissemination of information and ideas relating to the evolution of the building envelope. We have hosted luncheon seminar topics on technical and legal issues of many sorts, mostly involving keeping water out of the enclosure and optimisation of thermal performance. However, the building envelope separates the indoor (conditioned) environment from all of the elements contained in the exterior environment. These include, but are not necessarily limited to: heat, light (and other forms of electro-magnetic radiation), humidity, precipitation (in a number of forms), wind, pressure and sound . The mitigation of noise generation and transmission through the building envelope must be taken into consideration. When the envelope is designed, upgraded or repaired for controlling rain penetration or thermal resistance, the acoustic characteristics are often affected by the design decisions and not necessarily for the better. The speakers will introduce us to the basics of noise generation, transmission and mitigation, inside and out. They will lead a discussion and generally upgrade our knowledge in dealing with unwanted noise. Please join us in this informative and interesting presentation on the science and engineering of acoustics and how we can benefit from considering acoustics in our building designs.
