ActiveAcoustics - Determination of sound transmission loss in impedance tubes - Transfer matrix method
声学 阻抗管中传声损失的测量 传递矩阵法
Application Summary AI generated
This standard specifies the transfer matrix method for measuring sound transmission loss in impedance tubes. It is primarily applied in acoustical engineering and materials testing to evaluate the sound insulation performance of small samples, such as acoustic foams, panels, or muffler components, under normal incidence conditions. The method is used in laboratory settings for product development, quality control, and compliance testing in industries like automotive, aerospace, and building materials.
