Scope

Main technical content: This standard specifies the method for measuring the leakage noise of the whole vehicle in an aerodynamic-acoustic wind tunnel, including the basic conditions of the test, the measurement and sealing methods, the establishment of working conditions, the measurement process, evaluation parameters, record keeping, data processing, and measurement reports. This standard can evaluate the leakage noise level in the vehicle and diagnose the sources of wind noise and transmission path problems. This standard is applicable to automobiles with complete body sealing systems, and the maximum size of the vehicle must meet the requirements of the wind tunnel for vehicle weight and external dimensions.
