Scope: This standard specifies the test method for measuring tire noise mounted on a test vehicle or trailer under freewheeling conditions. Freewheeling is the condition in which the engine is off, there is no power drive, the transmission is in neutral, and the test tires are in a free-rolling state. The tire noise test results of the vehicle method are closer to the actual effect than the trailer method, but the tire noise is affected by the suspension parameters; the trailer method test results are closer to the actual noise generated by a single tire. This standard applies to passenger car tires and truck tires as defined in ISO 3833. It is neither suitable for measuring the tire noise (sound field distribution) of the vehicle under normal driving conditions, nor is it suitable for measuring the traffic noise and the degree of hazard at a given position of the vehicle under normal driving conditions.
