Abstract: A monolithic noise suppression device comprising a monolithic, integral baffle housing module. The module comprising, in turn, at least no welded joints or seams between the various components that make up the core of the module and no welded joints or seams between the core, or any structures that make up the core, and the various interior surfaces and/or structures that make up the body of the module. The module is preferably plastic and manufactured using a layered printing process. The monolithic, integral baffle housing module may include various other features that enhance performance, reduce manufacturing cost, facilitate customization and eliminate restrictions on disposability as compared to conventional noise suppression devices. The monolithic noise suppression device may further comprise a first stage noise suppression device to be used in conjunction with the monolithic, integral baffle housing module.
