The first measurement of neutral gas pressure modulation in the range of 10 kHz was performed using a piezoelectric transducer near the cylindrical inner wall surrounding microwave discharge plasma in the HYPER-I device. The signals from the transducer output were investigated with the ion saturation current signals from two Langmuir probes located at the plasma boundary layer.
