| 520 3# - SUMMARY, ETC. | |
| Summary, etc | Road surface noise can be measured by microphones mounted in close proximity to the tyre/road interface on a moving vehicle. The draft standard ISO/DIS 11819-2 defines the “CPX” measurement method that has been widely adopted by many road authorities and researchers. In New Zealand two CPX measurement systems have recently been developed in general accordance with this standard, but using different approaches: one with a conventional trailer, and the other with instrumentation fitted to a car. There are also differences in the instrumentation and data processing architecture between the systems. This paper compares the designs of the two systems and provides commentary on the requirements of the draft standard. |
