I first used HGC expertise some 17 years ago to solve a very tricky problem with commercial exhaust fan noise on a hotel project. HGC’s solution was so effective in reducing the fan noise level that it quelled all complaints from neighbors. Since that time I have used HGC expertise on a variety of Independent School projects with the primary emphasis on sound attenuation within the buildings and help with theatre acoustics. They are consummate professionals.”

We have worked with HGC on multiple projects in which the acoustics of a space has been critical.  This includes two performance theatres, university teaching environments, and multiple churches.  In all instances, we have been very pleased with the results.”

We’ve worked with HGC on a number of projects in the last 15 years and found this firm to be very professional and reliable. I will not hesitate to work with HGC on future projects.”

Not only is HGC one of the most technically astute environmental noise consulting firms in Ontario, but they are also reliable, efficient and genuine.  ORTECH has worked with HGC for 20 years and we continue to be impressed with their technical expertise and professionalism.”
