About Acoustic Material Testing Equipment
Acoustic material characterisation determines the sound absorption coefficient (α), acoustic impedance (Z), and transmission loss of porous absorbers, foams, composites, and surface treatments. The transfer function method (ISO 10534-2 / ASTM E1050) uses a standing-wave impedance tube with two precision measurement microphones and a loudspeaker source. Small-tube systems (29 mm, 100 Hz–6.4 kHz) and large-tube systems (100 mm, 50 Hz–1.7 kHz) cover different frequency ranges. Placid Asia supplies the Norsonic Nor1527 impedance tube and SPEKTRA SQ-6 acoustic coupler for laboratory and end-of-line production testing.

Frequently Asked Questions
What is the transfer function method for measuring sound absorption?
ISO 10534-2 describes the two-microphone transfer function method. A broadband signal is generated in the tube. The complex transfer function between the two microphone positions is used to calculate the normal-incidence sound absorption coefficient (αn) and acoustic impedance.
What tube diameter should I choose for my frequency range?
Small tubes (29–40 mm diameter) measure from ~200 Hz to 6 kHz. Large tubes (100 mm) extend down to ~50 Hz but are limited to ~1.7 kHz. The choice depends on the material's relevant frequency range and sample preparation constraints.
