T-Sonus Impedance Tube

TIERA's impedance tube kit for acoustic material characterization. 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.

Features

• Measures sound absorption coefficient and sound transmission loss
• Supports 2, 3 or 4 microphone impedance tube methods
• Compliant workflow for ISO 10534-2, ASTM E1050 and ASTM E2611
• Tube options: 100 mm, 30 mm and 16 mm for 50 Hz to 10 kHz coverage
• Pairs with a 4-channel PhonoVibe DAQ and Class I or Class II precision microphones
• TSONUS software covers calibration, measurement, averaging, merging and report generation
