Part Number:BSWA SW420
Impedance Tube, acoustic material testing SW series Impedance Tubes can accurately measure sound absorption coefficients and impedance according to standards described in ISO10534-2 (1998). They are based on the Transfer Function Method, which is much faster than the commonly used Standing Wave Ratio Method. The SW series Impedance Tubes are specially designed not only to work with the cut samples but also for direct use in the field. The small size and durable aluminium construction make it easy to transport and be used for estimating the properties of walls, ceilings, installed building materials, road surfaces, different ground surfaces, interiors of vehicles, etc. BSWA offers the complete set of Impedance Tube system, which includes: the tubes, microphones; DAQ hardware and measurement software.

SW420 measures Sound Absorption coefficient complying with GB, ISO and ASTM standards in the frequency range of 50 - 1800 Hz.
