声学 阻抗管中吸声系数和声阻抗的测量 第1部分:驻波比法
Application Summary AI generated
This standard specifies a method for measuring the sound absorption coefficient and acoustic impedance of materials using a standing wave ratio technique within an impedance tube. It is primarily applied in acoustical testing laboratories and by manufacturers of sound-absorbing materials, such as acoustic foams, panels, and fibrous insulations, to characterize their performance for use in building acoustics, automotive interiors, and noise control engineering.
