A specialty expertise of ATCO Acoustical Consultants is the acoustical retrofit of existing facilities. It is our experience that noise becomes a community issue when industrial sites expand or old machinery and equipment are replaced with newer, upgraded systems. Clients from a variety of industries have called upon our engineers to reduce noise from their facilities: power generation, quarries & landfills, recycling, bottling, refining, mining, gas compression, manufacturing, steel production, smelting, pulp & paper, and more.

For our clients who require acoustical retrofit services, our noise consultants first conduct a site noise survey that includes:

• noise level analysis at the nearest sensitive receivers
• measurement of noise levels of equipment at the facility
• determination of the heat load of the equipment
• assessment of the structural and mechanical adequacy of the facility to support noise control features
• appraisal of the operational requirements, including downtime and maintenance

Our site survey supplies the acoustical and facility information we use to design the acoustical retrofit solution.

Solutions can involve:

• acoustical upgrade of building envelope
• silencing equipment (enclosures, barriers, silencers, acoustical louvers, etc.)
• modifications to the HVAC (Heating, Ventilation, and Air Conditioning) system
• pipe and duct lagging
