GB/T 25077-2010 Acoustics—Materials for acoustical applications—Determination of airflow resistance
Abstract
This standard specifies two methods for measuring the flow resistance of porous sound-absorbing materials.
The specimens can be directly cut from porous material products.
Note: For references on the characteristics of airflow in laminar and turbulent states, please refer to Appendix A.
