INDUSTRIAL NOISE CONTROL PROJECTS

Nova Chemicals Corporation, Sarnia, Ontario

HGC Engineering made extensive use of sound intensity measurement to isolate the dominant segments of pipe-radiated sound in a complex of high pressure, high volume piping.

The detailed measurements were analyzed to develop noise control recommendations in the form of acoustical lagging of many lineal metres of piping.

Sound levels throughout the area were reduced by 10 dBA. The cost savings over alternative methods of noise control were in the order of several million dollars.

HGC Engineering also assisted Nova in installing permanent noise monitors at the property line at the facility.
