High Level Impedance Tube

Mecanum’s High Level impedance tubes are specifically designed to cover the 300 Hz to 6000 Hz frequency ranges and to go up to 155 dB.


Material Properties

➡ Normal incidence sound absorption coefficient (α)

➡ Normal incidence complex reflection coefficient (R)

➡ Normal surface impedance (Zs)

➡ Normal incidence sound transmission loss (TL)

➡ Characteristic impedance (Z)

➡ Wave number (k)

➡ Transfer matrix coefficients (Tij)

➡ Equivalent/effective dynamic density (ρeq)

➡ Equivalent/effective dynamic bulk modulus or compressibility (Keq)

TUBE SPECIFICATIONS

Tube Internal Diameter Frequency Range Available method
29 mm  300-6000 Hz 2, 3 and 4 microphones method

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 and the indirect method using the 3 microphones measurement.

ADDITIONAL INFORMATION

  • Every Mecanum High Level impedance tube is supplied with grids (for samples with low mechanical strength) and rings (to avoid leaks).

Main advantages of the product

Measurement method in accordance with the ASTM and ISO standards;

User-friendly interface;

Measurement method from the scientific literature including sine-sweep excitation that improves the signal to noise ratio;
