On-Site Acoustic Testing provides independent field testing 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.
From construction verification to persistent noise complaints, our work establishes what is happening and why. As an independent testing company, we provide findings without a product or installation sales interest.
ICD-705-related acoustic testing, design review, troubleshooting and field verification for secure and mission-critical environments.
02RF attenuation, shielding-performance and continuity measurements for projects requiring documented field performance.
03Field verification of walls, floors, ceilings, doors, facades and rooms for commercial, institutional and residential construction.
04Field testing for data center design, commissioning and operations, including community noise, equipment vibration, source localization and FLIR thermal investigation.
05Source localization, long-term monitoring, machinery and building-system measurements, community noise and diagnostic investigation.
06Independent testing for multifamily buildings, associations, pickleball and other amenity noise, mechanical systems and recurring resident complaints.

Case studies
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.

Indoor and outdoor surveys identified noise concerns and areas that were overlit or underlit, with recommendations that considered both guest visibility and turtle-nesting habitat.

Ground testing and a two-hour flight evaluated cabin announcements under operating conditions, informing headset selection, volume settings, and system gain staging.

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.
