On-Site Acoustic Testing is an independent field-testing company focused on acoustics, noise, vibration, secure facilities, RF shielding, indoor environmental conditions, and specialized technical investigations.
Field Measurement and Verification
Our work is performed at the installed condition: buildings, equipment, secure spaces, industrial facilities, data centers, residential properties, and other sites where measured performance matters more than a nominal product or laboratory rating.

Independent Technical Work
OSAT does not sell acoustical products or installation services. Our role is measurement, diagnosis, verification, and reporting so owners, engineers, contractors, facility operators, attorneys, and other project teams can make decisions from objective field data.
U.S. and International Projects
Projects are performed throughout the United States and internationally, from focused troubleshooting visits to formal standards-based acceptance testing and extended monitoring programs.
