Abstract: An acoustic device operative to generate high-power acoustic tones having a combustion based or chemical reaction based fluidic power source, an aeroacoustic generator, an assembly to provide feedback, and an array hosing that shapes the output pattern of the sound waves. The combustion or chemical/energetic reaction of one or more solid and/or liquid chemicals used as the source of pressurized gas is similar to a rocket engine or a gas generator which turns liquid and/or solid fuels into relatively massive volumes of pressurized gas. Examples of these generators are edge tone generators, sirens, vibrating reeds and unstable shock generators. In the case of edge tone generators, a physical resonant cavity assembly must be included around the effluent flow to provide feedback serving the purpose of stabilizing the output acoustical power and tonal properties. An array assembly is added to the aeroacoustic generator in order to shape the output pattern of the sound energy.
