HVAC plant, pumps, fans, compressors, and air handling units are among the most common sources of unacceptable noise in commercial buildings. QPT provides HVAC noise control solutions for Brisbane commercial facilities, assessing the source, transmission path, and receiver before specifying treatment — which may include acoustic enclosures, duct attenuators, flexible connections, and anti-vibration mounts.

Mechanical plant transmits vibration through structure and pipework, creating noise in spaces well away from the source.

For spaces requiring reverberation control, QPT supplies and installs acoustic wall panels, ceiling baffles, and acoustic ceiling systems. Applications include open-plan offices, meeting rooms, break-out spaces, recording studios and industrial environments where communication is safety-critical.
