Effect of time interval between pulses on the synthetic sound generated by repetitive nanosecond pulse discharge

The time interval between pulses is the key parameter of sound synthesis generated by repetitive nanosecond pulse discharge. In this paper, experimental studies on discharges at different intervals using a pin–pin electrode were carried out and time-domain waveforms obtained capacitor microphone. experiment results show that single discharge with FWHM (full width half maxima) 6 ns can produce much wider 16 μs because thermal inertia. Based measured waveform pressure burst modulation method, for better 100 Hz was theoretically determined to be shorter than 15 μs. However, it experimentally found too short gas recover its insulating ability from previous energy deposited into following are greatly reduced. synthetic considerably lower theoretical one.
