摘要：

Several methods presently exist for obtaining acoustical measurements of materials using an impedance tube. Three methods which offer both accuracy and convenience were chosen for this study. A brief summary of the theories of these methods and a comparative experimental study of them using the same apparatus and testing materials are presented to show their relative merits.
