When using a can periodically monitor A-weighted sound level of the system, the system of reading time interval should be less than 30ms. Or sound level meter Equivalent measurement system shall state provisions on verification of measuring instruments on a regular basis. GB 4569 2005 When using a sound level meter measurement 5.1.2 A characteristic of frequency weighting and "Fast (F)" stop time weighting characteristics. 5.1.3 beginning and end of each measurement should follow the manufacturer instructions for the press GB/T 15173 requirements for inspection and correction Associate sound level meter. Under no condition to make any adjustments, if after reading once a calibration calibration relative to the previous reading of the difference between type 1 Sound level meter is more than 0.5dB (A), type 2 sound level than 1dB (A), the measurement result is considered invalid after the previous calibration. Reading calibration measurement requirements shall be documented in Appendix A (informative) table. 5.1.4 measurement process, allowing the sound level meter according to specification requirements proper use of the windshield, but it should be noted that the spirit of the windshield on the microphone Sensitivity and directional influence. 5.2 vehicle speed and engine speed measuring instruments You should use a dedicated vehicle speed and engine tachometer measuring instruments, which should be consistent with the requirements of GB/T 5378 regulations. 5.3 Meteorological measuring instruments Anemometer, air pressure gauge and a thermometer should be consistent with GB/T 5378 regulations. 6 set-noise measurement method 6.1 Measurement Environment 6.1.1 measurement site (FIG. 1) Figure 1 Measurement of noise and field measurement area 6.1.1.1 Measurement site should be surface dry concrete, Asphalt or hard material having a high reflectance (excluding compaction Soil or other natural materials) consisting of flat ground. site It should be able to draw within a rectangular area measuring rectangular four Margins by test profiles (not including the handle) at least 3m, in this Shall not affect the sound level meter readings in the range of obstacles exist. Sound level meter microphone away from the edge of the road should not be less than 1m. 6.1.1.2 When surveyors and measurement other than the driver, in Shall have other staff in the measurement area. Surveyors and driving Members should not affect the position of meter readings. 6.1.2 Meteorology Measurement should be no rain, no snow and the wind speed is not greater than 3m/s the Carried out under the climatic conditions. Measurement should be excluded gusts of sound level meter Reading of. 6.1.3 Background noise Measurement, background noise (A-weighted sound level) to Less should test low noise 10dB (A) than to receive. 6.2 by commissioning and placement status 6.2.1 The test subject should be placed in the center of the rectangular measurement area (Fig. 1). 6.2.2 Commissioning the transmission in neutral, clutch is engaged, the driver in the normal driving conditions, the rear wheels can not overhead. If there is no empty Gear, wheels can be overhead, the drive wheel can be operated under no load condition. 6.2.3 If that is equipped with an automatic fan test, the measurement process should be undisturbed. 6.2.4 In the previously measured by test shall GB/T 5378 regulations warm-up operation, the engine temperature reaches normal operating requirements. 6.3 microphone placement and select the measuring point (Fig. 2) 6.3.1 microphone reference axis parallel to the ground, and the plane through the exhaust tone and flow direction perpendicular to the ground into a folder of 45 ° ± 10 ° angle. Relative to this plane, the microphone is located away from the subject test profiles (not including the handle) from the larger side. Microphone toward the exhaust Mouth, from the exhaust muffler tail pipe outlet 0.5m, and is located in the exhaust muffler tail pipe outlet of the same height, but the height from the ground shall not be less To 0.2m. GB 4569 2005 2 set-noise measurement microphone placed schematic diagram When the vehicle due to structural reasons can not meet this requirement, the microphone toward the exhaust port, located nearest the above conditions, and with the car The distance is greater than the 0.5m place, and should draw the measuring point diagram, mark the position of the microphone. 6.3.2 The test subject is equipped with two or more exhaust muffler, the muffler when the spacing is not more than 0.3m, just take a Measurement location, by selecting from the test profiles (not including the handle) recently muffler tail pipe outlet, or select from the ground up to the tail muffler Tube outlet. When the spacing between the muffler is greater than 0.3m, to deal with each muffler outlet measurement. 6.4 Operational requirements 6.4.1 The test measured by the following operating conditions. Engine speed. S is greater than 5000r/min, is taken as 1/2S; S is less than or equal to 5000r/min, taken as 3/4S. 6.4.2 stable after a specified engine speed, measured by the steady speed to slow down as soon as the sound level of the idle process. Time measurement should Including a short course of engine operation and constant deceleration all. 6.5 Value Requirements Measured as the maximum in each measurement position to repeat the test, each taking the maximum sound level measurements, take three consecutive measurement values The amount of results. 3 times the measured value of the difference between each other should not exceed 2dB (A), otherwise the measurement will be invalid. That is equipped with two or more test Muffler, take each point the maximum noise level measured value as a measurement result. Measured according to GB/T 5378 requirements rounded to the nearest whole number. 6.6 Measurement Record Measurement data and results of measurement conditions, that is test and measurement instruments and other technical parameters to fill in Annex A (informative) Table. If there should be noted that the case should be completed in the form of "additional instructions" column.
