Mecanum’s 2 microphones impedance tubes are specifically designed to measure the main normal indicators of a wide range of acoustical materials. The method is based on ASTM E1050 and ISO 10534-2 standards.
**Large spacing between µ1 and µ2 is essential for better results at low frequencies (as stated in ASTM E1050)
|Tube Internal Diameter||Frequency Range||High SPL Option|
|29 mm||200-6600 Hz||Available|
|44.44 mm||100-4300 Hz||N/A|
|100 mm||35-1900 Hz||N/A|
TUBE-X is a user-friendly software that will simplify the measurement procedure. It’s also fully compatible with FOAM-X software that can extract non-acoustic parameters of porous materials using the inverse method with a 2 microphones absorption measurement.
- All Mecanum impedance tubes are delivered with grids (for low mechanical strength samples) and rings (to avoid leaks).
- All Mecanum’s 2 microphones impedance tubes can be upgraded to 3 or 4 microphones, contact your Mecanum product expert for details.
