OSAT provides independent acoustic and diagnostic field testing for SCIF, SAPF, VTC, and other secure or mission-critical facilities.
Acoustic Verification for Secure Facilities
Testing can include airborne sound-isolation measurements, speech privacy and intelligibility measurements, diagnostic investigation of weak transmission paths, and verification after corrective work.
ICD-705-Related Field Work
Project scope is developed around the applicable facility criteria, construction documents, security requirements, and acceptance process. For the current OSAT secure-facility service overview, see SCIF, SAPF & VTC Acoustic Testing.
Diagnostic Investigation
Where a facility does not achieve the required acoustic performance, OSAT can use frequency analysis, source-localization techniques, targeted sound-isolation measurements, vibration measurements, and other field methods to help identify limiting paths or construction conditions.
