XSW4301 / XSW4331 Impedance Tube
XSW series impedance tubes are a new type of impedance tube product designed by BSWA based on the transfer-function method. They were designed and processed by ZKXY. The impedance tubes are compact in design, lightweight, and easy to assemble, making material replacement more convenient and rapid. As a supplement to the SW 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 SW series.
The XSW 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
