Acoustic Properties of Material Measurement-Reflection Coefficient, Absorption Coefficient
本量測系統主要建構在B&K TL系統中，搭配符合ASTM與ISO規範之B&K 大小管徑之阻抗管進行材料聲學特性的量測，所獲得的特性主要來自材料對於聲波垂直入射的影響。
可獲得的特性與參數有: 反射係數、透射損失、吸音係數、材料的聲學阻抗
[This measurement system is mainly used to obtain the basic acoustic properties of material based on the B&K impedance tube(Large & Small tube) and rekated B&K instruments with TL signal analysis system.]
