Acoustical Testing Services

The principal tests performed in our reverberation chambers involve sound absorption, sound transmission loss, impact sound transmission, sound power, sound pressure, and dB(A) measurements—all of which are monitored in a central control room. Whether NRC tests, E90 testing, STC tests, or other acoustical testing, we provide clients with printouts, including both data and graphical presentations, immediately following the completion of each test for a record of performance.
