PRESSURE WAVEFORM MEASURING DEVICE AND MEASURING METHOD

摘要

<P>PROBLEM TO BE SOLVED: To provide a pressure waveform measuring device and method for a planar pressure wave propagating toward an opening end part within a conduit-like space. Ž<P>SOLUTION: The device includes a plurality of pressure waveform measuring means provided separately along the conduit-like space; and a data processing means phase-shifting pressure waveform data obtained by the pressure waveform measuring means to a reference position along the conduit-like space to obtain a pressure waveform in the reference position from which reflected waves reflected by the opening end part are removed.
