声学 多孔吸声材料流阻测量
Application Summary AI generated
This standard specifies the method for measuring the airflow resistance of porous sound-absorbing materials. It is applied in the acoustical engineering and building materials industries to characterize how easily air passes through materials like fiberglass, foam, or mineral wool, which directly affects their sound absorption performance. The test is critical for quality control and product development of acoustic panels, mufflers, and noise control treatments.
