HGC Engineering has conducted acoustical audits and acoustical assessment reports, noise contouring and workplace and environmental noise studies for a wide assortment of manufacturing facilities in Canada.

Xerox Research Facility, Oakville, Ontario
Compliance with the environmental noise emission limits was verified for this large scale and complex research and production facility, using sound intensity analysis. Despite significant interference from the traffic noise produced by the nearby expressway, HGC Engineering was able to demonstrate acceptable sound emission levels toward obtaining environmental approvals.

Kraft Foods Canada, facilities throughout Ontario
HGC Engineering undertook initial pre-audit screening assessments and detailed acoustic assessments for many Kraft facilities throughout Ontario.

The projects included assessment of existing operations, acoustic design of new projects, and noise control measures to achieve off-site sound level limits. Sites included Cobourg, Niagara Falls, and locations throughout the Greater Toronto Area.

Owens Corning Fibreglass Facility, Toronto
HGC Engineering undertook an acoustic assessment of this large scale production facility in 2004 to 2006, both toward consolidating the environmental approvals and in anticipation of process expansion. The expansions were completed in 2005, with no net increase to the sound emissions of the facility.
