Acoustic Changes to the Ontario Building Code


Nicholas Sylvestre-Williams
 Principal, aercoustics Engineering Limited

The next version of the OBC will be introducing significant changes to the acoustics requirements for 
construction, under Section 5.9 & 9.11. The current 2012 code, simply put, requires walls to meet a Sound
Transmission Class (STC) 50. The proposed changes introduce the concept of Apparent STC (ASTC). 

This presentation will focus on the upcoming changes to the OBC pertaining to acoustics with an
introduction to the concepts of Transmission Loss, STC, and ASTC, and connecting these concepts to
what the new code brings and their impact on design and construction.

Nicholas Sylvestre-Williams is a principal with aercoustics Engineering Limited, Canada’s leading acoustics, noise & vibration consulting firm. He is a registered professional engineer in Ontario and several other Provinces, as well as a Designated Consulting Engineer in Ontario. He has been active in the field of noise & vibration for 15 years, having worked on a large number of projects, both nationally and internationally, over his career. He has been focused on residential development projects and is currently working on The One, Canada’s first super-tall residential building. Nicholas is the Chair of the American National Standards Institute (ANSI) group on Room Acoustics and is heavily involved in the development of standards and guidelines as they relate to acoustics.

Toronto Chapter of Construction Specifications Canada
and Ontario Glass & Metal Association
invite you to attend

A CSC/OGMA Educational Collaboration

Thursday, November 14, 2019
9:30 a.m. to 3:00 p.m.
Richmond Hill Country Club

The Toronto Chapter of Construction Specifications Canada and the Ontario Glass & Metal Association are excited to team up to produce an educational event that will be both informative and entertaining. Share the Vision will be held at the Richmond Hill Country Club on
Thursday, November 14, 2019, from 9:30 a.m. to 3:00 p.m.

Some of the topics we’re working on include:

  • Reducing sound transmission in buildings: New technology interlayers developed for laminated glazing are reducing the noise heard through windows (Continuing Education accredited).
  • The new Ontario Construction Act: Updates on the status of the Act's implementation and how you can use the new laws to protect your business.
  • Emerging technologies in glass: Vacuum glass is expected to make a huge improvement in the thermal conductivity of glass. Nanotechnology will virtually eliminate glass reflection and glare. 
  • Building envelope failures: We will look at a few case studies, the causes of some of the worst building failures, and how to avoid them. 
 Please mark the date in your calendar now and plan to attend this highly educational event. A continental breakfast and lunch will be served.

Look for registration details in your inbox in mid-October.
