Abstract: An acoustically variable burner system is provided, having a burner wherein the flow of gas thereto, and consequently the flame pattern resulting from the ignition of the gas, is variable by transmission of acoustic waves therethrough via an acoustically-based control system. The preferred burner design produces a realistic, wood-burning type flame pattern. An acoustic controller, such as an APPLE® iPod®, MP3 player, computer, etc., may be utilized to drive/control electroacoustic transducers positioned adjacent the burner, the sound waves of which are produced thereby varying the flow rate of gas to the burner gas ports, thereby varying the flame height in direct correspondence with the audio signal. Further, the flame color may be altered by introduction of flame color variant compositions exposed to the flame via a flame color variation device removably positioned adjacent the burner.
