ABSTRACT:
A muffler including paraboloid steel baffle chambers which may contain a continuously encased vacuum. These chambers can be shaped out of steel paraboloids. The exhaust of the engine (or noise source) can flow into the space between chambers and out of the muffler with high efficiency. The paraboloids are designed so that the noise is reflected to maximize a sound wave's path and minimize its intensity.
