Abstract
A tire defect detection system including a support structure for receiving a tire; an actuator disposed proximate the tire for impacting the tire; a microphone disposed proximate the actuator for receiving a sound wave generated when the actuator impacts the tire; and a computer responsive to the microphone, the computer programmed to calculate a number of discriminator quantities from the resulting sound wave and to compare the calculated discriminator quantities with stored discriminator quantities indicative of a defect to determine whether a defect is present in the tire.
