Acoustic Impedance and Sound Transmission Tubes

Machined aluminum tubes with mounting ports for microphones. Available in three diameters (28mm, 45mm and 100 mm) and configurable for either normal incidence sound absorption or sound transmission measurements.

Machined aluminum construction reduces influence of background noise and tube wall absorption.

Use with our Trident data acquisition software and EZ1050 or EZ-NITL applications for post process analysis.
