Abstract
Noise generated by load supporting elements of an apparatus (e.g., tread 12 of a tire 10) having a plurality of repeating design cycles 14 is spread over a broad frequency spectrum. This is accomplished by making the apparatus with the load supporting elements (e.g. tread lugs) arranged in accordance with the following procedure. First, determining the maximum number of repeating design cycles 14 which may be placed about the apparatus, the design cycles being of at least two different lengths; Second, selecting a maximum pitch ratio i.e. ratio of maximum and minimum design cycle lengths; Third, determining the appropriate number of harmonic segments 16 which the apparatus can be divided into; Fourth, determining the size of each of the harmonic segments 16 and the number of design cycles 14 for each of the harmonic segments; Fifth, arranging the various design cycles 14 in each of the harmonic segments 16 so that the wave length of the predominant modulation frequency of the segment corresponds to the fundamental length of that segment.
