Abstract
A method of simulating noise generated by a tire using a computer, wherein waveforms of the sounds are determined, considering the phase, of which sounds originate from sources of sound, namely, a leading edge which is an edge of the load-supporting portion of the tread and first contacts the road surface when the tire rotates, and a trailing edge positioned opposite to the leading edge. The so-determined waveforms of the sound are integrated over the entire surface of the tread, after that, audible sound of the integrated waveforms is emitted from a headphone as tire-noise.
