DEVICE AND METHOD FOR SILENCING NOISE ACOUSTIC WAVES

摘要

A device and method for silencing noise acoustic waves generated by a source of noise, such as an internal combustion engine. The device comprises a pipe (2) prepared to make the noise acoustic waves circulate through its interior (6); a metal cathode (3) located on the outer wall of the pipe (2); a metal anode (5) located on the inner portion of the pipe (2); and a winding (8, 9) configured to increase the voltage of the cathode (3) and generate, in the interior (6) of the pipe, electric arcs (4) that emerge from the cathode (3) to hit on the anode (5). The device generates a non-destructive electric arc capable of silencing the acoustic sound wave generated by the source of noise.
