汽车车内噪声测试与分析
Test and Analysis of Inner Noise of Automobiles
摘要
Abstract
Noise of different positions inside a car were tested and analyzed, and the noise distribution was researched. The results show that the inner noise is increased by 4 dB (A) with the car’s speed raised by 10 km/h. Noises are different between front seat and back seat, and their frequency ranges of the noises are 125~200 Hz and 800~2 000 Hz respectively. Wind noise can make difference of the noise between left and right ears. This difference increases initially and then decreases with the increasing of the car’s speed. Sedan car’s noise situation of the back seat is better than that of Hatchback car’s. These results are of reference value in noise control design of automobiles.关键词
