“…Thus, the amplitude of power oscillations in an arc discharge experiment with copper electrodes in the atmosphere is about 1%-10%. 6,7 Whereas in an arc discharge experiment with carbon electrodes in a noble gas, there can be intense transverse oscillations of the arc channel with a frequency of about 100 Hz and current amplitude oscillations of up to 50%. 5 In the peripheral region of an arc with graphite electrodes burning in a high pressure inert gas, a large number of microscopic soot particles are produced together with nanoparticles.…”

We suggest a simple theory to describe the sound generated by small periodic perturbations of a cylindrical arc in a dense gas. Theoretical analysis was done within the framework of the non-selfconsistent channel arc model and supplemented with time-dependent gas dynamic equations. It is shown that an arc with power amplitude oscillations on the order of several percent is a source of sound whose intensity is comparable with external ultrasound sources used in experiments to increase the yield of nanoparticles in the high pressure arc systems for nanoparticle synthesis.
