Claim 0:
1. An NVH-reducing driveshaft damper, comprising:
a tubular structure defining an inner surface and an outer surface; and
a unitary polymeric attenuation strip helically wound around the tubular structure at a pitch angle θ and positioned on the tubular structure, wherein the attenuation strip (i) includes a plurality of elongate protrusions extending upwardly from a base and positioned inwardly from the base's lateral edges, (ii) has a base-to-protrusion ratio BPR of at least 5, BPR being equal to the base's width between its lateral edges divided by the protrusion height of the tallest elongate protrusion, (iii) has a protrusion-spacing ratio PSR of at least 1, PSR being equal to the mean spacing between adjacent elongate protrusions divided by the protrusion height of the tallest elongate protrusion, and (iv) has a ratio of the protrusion height of the tallest elongate protrusion to the maximum protrusion width of the tallest elongate protrusion of between 2 and 4.
