How are the acoustic properties of polyester fiber acoustic panels tested?

2026-06-29
Acoustic performance testing is typically conducted according to GB/T 20247-2006 "Acoustics—Measurement of Sound Absorption Properties of Materials by Reverberation Chamber Method," or alternatively according to international standards ISO 354 or ASTM C423. It is recommended to choose a third-party testing organization with CMA and CNAS accreditations to issue the test report.
