Impedance Tube SW230

BSWA  SW series impedance tube can accurately measure sound absorption coefficients and material impedance values according to standards described in ISO10534-2 (1998). SW series iimpedance tube is based on the Transfer Function Method, which is much faster than the commonly used Standing Wave Ratio Method. The Transfer Function Method separates the incident and reflected energy from the measured transfer function, and then estimates the acoustic properties of the test sample that is located at the end of the tube.

SW230 impedance tube can measure the sound absorption coefficients with the frequency range between 125Hz~3150Hz
