On-Site Acoustic Testing, LLC (OSAT) provides independent acoustic, RF shielding, noise and vibration field testing for U.S. government agencies, military installations, defense contractors and prime contractors. We support secure facilities and mission-critical buildings throughout the United States and internationally.
OSAT provides independent measurement and verification rather than selling soundproofing products, shielding systems or installation services. Our work supports design and construction review, commissioning and acceptance, troubleshooting, remediation verification and retesting.
