Material Testing

Material Testing

Materials have two important acoustic properties:

  • Sound Absorption Coefficients
  • Sound Transmission Loss (Sound Insulation Index)

BSWA supplies the following products for your material testing use:

SW series impedance tube

Can make Sound Absorption Coefficients and Sound Transmission Loss measurements.

Detail

F100/F50 square impedance tube

Designed base on transfer-function method, according to GB/T 18696.2, GB/J 88, ISO 10534-2, ASTM E1050-12, and ASTM E2611-17 standards, including absorption tube kit and transmission loss tube kit.

Detail

R-Cabin

Small reverberation chamber which can be used to measure the sound absorption of small and irregular samples, such as car seat, roof panel, carpet and etc.

Detail

MC3642A/B

4 input channels (with 4 adjustable gains) and 2 output channels, can simultaneously analyze 4 channels of acoustic and vibration signals. It can apply to most acoustic and vibration testing with the VA-Lab measurement software.

Detail

MC3242

4-channel hardware designed for analyzing acoustic and vibration signals acquired simultaneously from its 4 channels. It can be used with BSWA VA-Lab software and BSWA impedance tubes to make sound transmission loss test.

Detail

VA-Lab IMP

Acoustical measurement software for impedance tube testing. It supports sound absorption and sound insulation measurements in BSWA SW series impedance tubes.
