Application Summary AI generated

This standard specifies the static airflow method for measuring the airflow resistance of porous materials, such as acoustic foams, fibrous insulation, and perforated panels. It is applied in acoustical engineering and product testing to characterize how easily air passes through a material, which is critical for predicting sound absorption and transmission loss in building, automotive, and industrial noise control applications.
