University Material Research: Impedance Tube for Sound Absorption Measurement

A university acoustics laboratory required an impedance tube system for characterising novel acoustic materials developed in their research programme. The PLACID impedance tube system provided ISO 10534-2 compliant measurements across the frequency range of interest, with results traceable through accredited calibration.

• Application: Characterisation of porous acoustic absorbers and membrane absorbers
• Standard: ISO 10534-2 transfer function method
• System: PLACID impedance tube with 29 mm and 100 mm tube sections
• Frequency coverage: 50 Hz to 6.3 kHz combined
