Direct-Reading One-Port Acoustic Network Analyzer
A novel measurement instrument is proposed to perform reflection measurements of guided acoustic waves. Both the magnitude and the phase of the reflection coefficient are measured simultaneously. The compact construction and the direct-readout feature facilitate an attractive measurement alternative for traditional standing-wave-ratio (SWR) detectors with movable microphones. These advantages are decisive for infrasonic frequencies where traditional SWR detectors require setups of 10m or more.
