Investigation & verification

Understand the source.
Verify the solution.

Noise and vibration problems can arise from mechanical equipment, building systems, industrial operations, exterior sources, or sound transmission between spaces. We investigate the source and transmission paths, document operating conditions, and use field measurements to identify contributing factors, guide corrective measures, and verify performance.
