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.

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.

Noise and lighting at a luxury waterfront hotel.

Guest comfort, safe walkways, and a sensitive shoreline.

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.

Speech intelligibility, tested in flight.

Recommendations adopted across a fleet of similar aircraft.

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

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.
