Abstract: An acoustical silencer (10) includes a housing (12) extending generally axially vertically upwardly from an inlet (14) to an outlet (16). A laterally extending upper divider wall (18) is attached to the housing and has a plurality of apertures (22) therethrough. A plurality of tubes (24, 34) extend axially vertically through respective apertures and have an integral bulge (26) crimped radially outwardly to a larger radius than the aperture and engaging the topside of the upper divider wall to suspend the tube therefrom. A laterally extending lower divider wall (28) has a plurality of apertures (30) therethrough. The tubes extend axially vertically through the apertures of the lower divider wall and some have integral bulges (32) crimped radially outwardly to a larger radius than the aperture of the lower divider wall and engage the underside of the lower divider wall to suspend the latter from the tubes.
