On-Site Acoustic Testing provides independent product-noise measurement, verification, and documentation for manufacturers, equipment suppliers, engineers, and purchasers who need defensible sound-emission data.
Product noise testing
OSAT can measure and document the noise produced by machinery, equipment, appliances, building systems, and other products under defined operating conditions. Testing can support product development, procurement, compliance documentation, acceptance testing, and investigation of field complaints.
- Sound-pressure and sound-emission measurements
- Octave-band and one-third-octave-band analysis
- Operating-condition comparisons
- Before-and-after design or mitigation measurements
- Source localization and dominant-noise investigation
- Field and project-specific test protocols
ISO 4871 noise declarations
ISO 4871 addresses the declaration and verification of noise-emission values for machinery and equipment. OSAT can provide measurement and verification support for projects where manufacturers, suppliers, owners, or purchasers need documented declared noise-emission values or independent confirmation of stated performance.
- Measurement support for declared noise-emission values
- Verification of manufacturer or supplier noise data
- Independent testing for procurement and acceptance
- Documentation of stated operating conditions and measurement results
- Comparison of measured and declared product-noise performance
For manufacturers and product developers
Independent measurements can be used during development to identify dominant sources, compare prototypes or design revisions, evaluate noise-control changes, and establish repeatable product-noise data before release or specification.
For purchasers, owners, and commissioning teams
When equipment is purchased with a stated acoustic requirement, field or project-specific verification can help determine whether installed or delivered equipment performs as represented. Testing can also help resolve discrepancies between published data and actual operating conditions.
Machinery and equipment investigations
Product-noise work can include fans, pumps, motors, mechanical equipment, industrial machinery, packaged systems, appliances, specialty equipment, and other noise-producing products. The appropriate measurement method depends on the product, operating condition, environment, and applicable specification.
Independent documentation
OSAT is an independent testing company. We do not sell noise-control products or equipment. Our role is to measure actual performance, document test conditions and results, and provide technically defensible reporting appropriate to the project.
