ISO 10844 Acoustics – Specification of Test Tracks for Measuring Noise Emitted by Road Vehicles and Their Tires
If you are an automotive company, a tire company, or a test track owner and you are involved with vehicle exterior noise measurements, then you must know about standard ISO 10844. Common vehicle pass-by noise testing (such as ISO 362 and ISO 13325) is required to be conducted on a test track conforming to ISO 10844. Characteristics of a test track can significantly influence the exterior vehicle noise measurement. In particular, pavement surface texture affects the noise generated by the tires. The shape, flatness, and sound absorption properties of the track affect how the sound propagates away from the vehicle. The purpose of the ISO 10844 standard is to specify the noise test track in a manner that minimizes the variation of vehicle noise measurements made at different testing locations.
