On-Site Acoustic Testing provides independent noise and vibration assessment of HVAC systems, pumps, fans, rooftop equipment, generators, mechanical rooms, and other building systems affecting residential, commercial, and institutional spaces.
Mechanical equipment noise
Building equipment can produce broadband, tonal, low-frequency, intermittent, or cyclical noise that is difficult to characterize with a single short measurement. Testing can document actual operating levels, frequency content, affected locations, and changes between equipment states.
- HVAC and rooftop equipment noise
- Chillers, condensers, cooling towers, and air handlers
- Pumps, fans, motors, compressors, and generators
- Mechanical-room and penthouse noise
- Interior and exterior receiver measurements
- Property-line and neighboring-property measurements
Structure-borne vibration
Rotating and reciprocating equipment can transmit vibration through slabs, framing, piping, curbs, and equipment supports. Sound and vibration measurements can be used together to distinguish airborne noise from structure-borne transmission and identify dominant paths.
Long-term and remote monitoring
When equipment cycles intermittently or complaints occur primarily at night, long-term and remote noise and vibration monitoring can document operating patterns over days, weeks, months, or longer. Optional sound and video recording may also be used where appropriate to correlate measured events with site conditions.
Comparative and mitigation testing
Measurements can compare individual equipment configurations, operating loads, before-and-after repair conditions, and pre- and post-mitigation performance. This is useful when evaluating aging equipment, isolation systems, barriers, operational changes, or equipment replacement.
Independent field verification
OSAT does not sell mechanical equipment, vibration isolators, or acoustic treatment products. Our role is to measure actual field conditions and provide objective technical documentation for owners, HOAs, property managers, engineers, contractors, and other project stakeholders.
