Impedance Tube for Absorption Using 2 Microphones

 

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)

   

MATERIAL PROPERTIES

➡ Normal incidence sound absorption coefficient (α)

➡ Normal incidence complex reflection coefficient (R)

➡ Normal surface impedance (Zs)

 

TUBE SPECIFICATIONS

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 SOFTWARE

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.

ADDITIONAL INFORMATIONS

  • 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.
