摘要：

A measuring probe has been built that is comprised of an electrostatic transducer as a source and two receiving microphones. This probe allows measurements of acoustic impedance to be made over a wide range of values and over a larger frequency range than hitherto possible in waveguides by separating the contributions of the plane and first helical modes to the impedance.
