Kingdom has released a new materials measuring instrument from BSWA which manufacturers sophisticated sound sensing and measuring devices.

The BSWA SW series of sound Impedance Tubes can accurately measure sound absorption coefficients and impedance according to standards described in ISO10534-2 (1998) using the Transfer Function method.

The SW series Impedance Tubes are specially designed not only to work with the cut samples, but also for direct measurements in the field.

The small size and durable aluminium construction make it easy to transport the tubes which are supplied with a robust transport case.

The tubes have a wide application and can be used for estimating the absorption and impedance properties of walls, ceilings, installed building materials, materials used in the manufacturer of goods and products, for road surface and different ground surface measurement and the characteristics of vehicle interiors as some examples of their applications.

The tubes are supplied with an integrated 20W loud speaker in the impedance tube which supplies the excitation energy.

The BSWA Impedance Tube system includes the tubes, optional microphones, acquisition hardware and VA-Lab measurement software.

The optional VA-Lab analysis software provides all measurement functions for sound absorption and transmission loss testing.

The BSWA SW230/260 Impedance Tubes are intended to be used over the measurement frequency range from 125 Hz to 6300 Hz using two locations for optional 1/4" microphones which measure sound pressures.

SW433/463 Impedance Tubes are designed to measure both sound absorption coefficients and transmissions loss over 125 Hz to 3250 and 6300 Hz and use four optional 1/4" microphones for measuring sound pressures along the tubes.
