Nor1527
Kundt impedance tube
Material Sound Transmission Loss and Acoustic Impedance Tube Systems
Nor1527 acoustic performance measurement system is an acoustic impedance, sound transmission loss and sound absorption coefficient measurement system operating in accordance with ASTM E-2611, ASTM E-1050, ISO 10534-2 standards. Measurements can be made at a frequency of 50Hz – 6400 Hz, under room conditions, temperature and pressure. There are 2 different diameter tubes (100 mm, 30 mm diameter) for low and high frequency measurements.
Applications
- ASTM E2611 (4 Pole Transfer Matrix Method) measurement method
- ASTM E1050 and ISO 10534-2 (Transfer Function Method) measurement method
