Impedance Tubes for Sound Absorption Analysis
BSWA Solutions
BSWA SW series Impedance Tubes can accurately measure sound absorption coefficients and impedance according to relative ISO and ASTM standards. They also support the sound transmission loss measurements based on the Transfer Function Method. The Transfer Function Method separates the incident and reflected energy from the measured transfer function, and then estimates the acoustic properties of the tested sample installed in the tube.
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 be transported and used for estimating the properties of vehicle interiors, for instance. BSWA offers the complete Impedance Tube system, which includes the tubes, microphones, DAQ hardware and measurement software.
