Independent testing for demanding environments.

Acoustics · Noise · Vibration · RF shielding · Air quality

On-Site Acoustic Testing provides independent acoustic testing services for secure facilities, data centers, buildings, aircraft, industrial equipment, and products, as well as environmental noise and vibration. We identify sources and transmission paths, help teams correct problems, and retest to verify results.

Selected organizations associated with projects performed by OSAT. Organization names identify project experience and do not imply endorsement or affiliation.

Case studies

Field experience. Documented results.

Explore all case studies

Every door verified to its required rating.

More than 60 doors. Full acoustic compliance at completion.

All doors initially failed. Advice on seals, caulking, and fitment, installer training, and real-time feedback helped bring 100% of the doors to their required rating by the end of testing.

Existing SCIFs assessed and retested.

Acoustic deficiencies identified in occupied secure areas.

OSAT tested perimeter assemblies, doors, and inter-room transmission at a defense-contractor headquarters. Following corrective work, retesting verified the applicable ICD-705 acoustic requirements.

Independent noise evidence for a data center.

Field measurement and review of disputed noise readings.

Property-boundary measurements and a review of instrument suitability, calibration and test methods informed a data-center noise dispute. The principal legal action was subsequently withdrawn; a limited ordinance matter remained.

Investigation & verification

Understand the source.
Verify the solution.

A weak door seal, a concealed transmission path, or vibration carried through a structure can undermine an otherwise sound design. We investigate the installed condition, identify likely causes, and use field measurements to guide remediation and verify performance.
