GB/T 6446-1986 《Frequency weighting for the measurement of aircraft noise (D-weighting)》 Related products

GB/T 6446-1986 is a standard in the field of aircraft noise measurement. It focuses on the Frequency Weighting (D-Weighting) method used in aircraft noise measurement. It is clear that its application scenario is aircraft noise measurement. Based on the acoustic principle, D-Weighting weights aircraft noise of different Frequencies through specific Frequency Response characteristics, so that the measurement results are more suitable for the actual perception of aircraft noise by the human ear. The standard specifies the specific parameters and implementation methods of D-Weighting, which provides a unified specification for aircraft noise measurement and helps to accurately evaluate the impact of aircraft noise on the surrounding environment and people.
