Abstract
A system for suppressing sound from a flame comprises a detector for detecting a first signal which emanates from the flame. A photo sensor rapidly detects the noise from the flame. The first signal is inverted to produce a second signal. The second signal is applied to the flame for cancelling the sound produced by the flame. Preferably, an electric arc is produced between a cathode positioned in the flame and an anode positioned around the flame. The electric arc is modulated by the second signal.
