Combines 16 mm, 30 mm and 100 mm tube options, precision microphones, PhonoVibe DAQ, signal generation and TSONUS software to measure absorption coefficient and sound transmission loss.T-Sonus extends the TIERA sound and vibration ecosystem into acoustic material testing. The workflow is intended for laboratories that need a controlled way to compare foam, panels, liners, ducts, enclosures and other materials using a repeatable normal-incidence tube measurement setup.
The system uses mounted loudspeakers to create a controlled sound field inside the tube. Precision microphones measure sound pressure at defined locations, while the PhonoVibe acquisition system transfers the signals to TSONUS software for processing.

The engineering behind this product
Why this measurement is made, how it goes wrong, and what the numbers mean — written by the people who build the instrument.
AcousticsMeasuring Sound Absorption in an Impedance Tube — and Why Your Number Disagrees With the DatasheetThe two-microphone transfer-function method (ISO 10534-2) measures a material's normal-incidence absorption coefficient in a tube the size of a drainpipe. It is fast, repeatable and cheap — and it answers a narrower question than most people think, which is exactly why lab numbers and reverberation-room numbers disagree.9 min read · Read →
