XSW4301 / XSW4331 Impedance Tube
2026-03-25
XSW43X1 series impedance tubes are
a new type of impedance tube product designed by BSWA based on the
transfer-function method. The impedance tubes are compact in design,
lightweight, and easy to assemble, making material replacement more convenient
and rapid. As a supplement to the SW42X1 and SW46X1 series impedance tubes,
they are suitable for users who are concerned about the mid-frequency
performance of the materials. One set of tubes can complete the required
frequency band testing. If a wider frequency range is needed, please choose the
impedance tubes of the SW42X1 and SW46X1 series.
The XSW43X1 series
impedance tubes are designed based on the two-microphone transfer function
method. Paired with the MCR impedance tube software, the measurable material
parameters include: sound absorption coefficient, reflection coefficient,
acoustic impedance rate, acoustic admittance rate, transmission loss,
propagation wave number, etc.
Features:
● Acoustical
properties of material measurements based on the transfer-function method
according to not only absorption coefficient standard of GB/T 18696.2, GB/J 88,
ISO 10534-2 and ASTM E1050-12, but also transmission loss standard of ASTM
E2611–17
● Separable
sample holder tube is convenient for placement of materials to be test
● Faster
and more accurate compared to the standing wave ratio method
● Combined
measurements with different microphone spacings can cover a wider
frequency range
● The
inner diameter is 50mm, which lies between the commonly used 100mm and 29mm
pipes in the market. It meets the requirements for inter-pipe sealing and snap
connection structure in the conventional frequency band. The structure has been
improved, significantly enhancing the sealing and sound insulation
performance, and making the pipe installation more convenient and rapid.
Applications:
● Quantitative
measurement of acoustic properties of materials
● Measure
the acoustic coefficients of materials which required for simulation software
