ABSTRACT:
A low cost wave interference silencer including an enclosure having an inlet and an outlet with a direct bypass communication therebetween with a first acoustical length and further including a plurality of flat fin components enclosed between wall segments of the enclosure to define a plurality of series-connected flow paths arranged in spaced parallelism and including segments in reverse flow relationship to define a second flow path between the inlet and the outlet having an acoustical length greater than that of first acoustical length to produce a phase shift of a sound frequency within the exhaust flow between the inlet and the outlet and a resultant wave interference attenuation thereof.
