ABSTRACT:
Circumferentially separate tire pitch sequences are selectively positioned for suppressing tire noise by comparing waveform representations of the separate pitch sequences in a correlation function and using the magnitude of a Hilbert Transform to identify minima of the absolute value of the correlation function. The relative rotated position of the pitch sequences for suppressing tire noise is selected from the vicinity of one of the minima.
