TUBE – HIGH LEVEL IMPEDANCE TUBE
Enquiry Item
The high sound level impedance tube, having a diameter of 29mm, is designed to measure the main acoustic indicators of a wide range of acoustic materials using 2, 3 or 4 microphone methods. In in situ configuration, it will be ideal for measuring the surface impedance of aeronautical liners or perforated plates and thus studying their non-linear behavior at high levels (155 dB).
