On-Site Acoustic Testing provides independent field measurement and diagnostic testing for data centers, supporting owners, operators, design teams, commissioning teams, neighboring properties, municipalities, and other stakeholders.
Data center noise testing
Data centers can generate substantial and highly tonal sound from cooling equipment, generators, transformers, rooftop systems, air handlers, fans, pumps, and other mechanical infrastructure. OSAT performs field measurements to document both facility performance and off-site impact.
- Property-line and community noise surveys
- Daytime and nighttime environmental noise measurements
- Octave-band and one-third-octave-band analysis
- Tonal and low-frequency noise investigation
- Source localization and contribution analysis
- Long-term unattended noise monitoring
- Before-and-after mitigation verification
- Commissioning and acceptance testing
For data center owners, operators, and design teams
Field testing can identify which systems actually control the acoustic environment after construction and during operation. Measurements can be used to verify design assumptions, investigate complaints, establish baseline conditions, evaluate mitigation measures, and support commissioning or expansion projects.
- Mechanical and electrical equipment noise
- Cooling-system and chiller performance
- Generator and emergency-system noise
- Rooftop and exterior plant measurements
- Interior equipment-room and occupied-space noise
- Vibration transmission through slabs, structures, piping, and equipment supports
- Operational comparisons under different loads and equipment configurations
Vibration testing
OSAT can measure vibration associated with rotating equipment, cooling systems, generators, pumps, structural transmission paths, and other data center infrastructure. Testing can help distinguish airborne-noise problems from structure-borne vibration and identify dominant transmission paths.
- Equipment and structural vibration measurements
- Frequency-domain analysis
- Source and transmission-path investigation
- Baseline and comparative measurements
- Verification following isolation or mitigation work
Thermal imaging and temperature investigation
Thermal imaging can be used alongside acoustic and vibration measurements to document temperature patterns and help investigate mechanical, airflow, enclosure, and equipment conditions. OSAT can provide FLIR-based thermal imaging and field temperature measurements where they are useful to the project scope.
- Thermal imaging of equipment and building systems
- Surface-temperature mapping
- Identification of anomalous hot or cold areas
- Comparative measurements under operating conditions
- Documentation for troubleshooting and commissioning support
Community and neighboring-property investigations
For residents, property owners, HOAs, municipalities, and other parties affected by data center operations, independent measurements can establish what sound is present, when it occurs, its frequency content, and how it compares with applicable criteria or baseline conditions.
- Residential and property-line measurements
- Nighttime and low-background-noise conditions
- Low-frequency hum and tonal-noise investigation
- Long-term monitoring to document operating cycles
- Independent documentation for planning, disputes, or mitigation review
Independent field verification
OSAT is an independent testing company. We do not sell data center equipment, acoustic products, vibration isolators, or mitigation systems. Our role is to measure actual field conditions, identify dominant sources and transmission paths, and provide clear technical documentation.
