进气噪声原理的研究探讨与降噪措施

Reseach on air admission noise theory and measures of noise reduction

对进气噪声的产生原理进行分析和研究，利用赫姆霍兹谐振消声器的设计原理，设计了适合某车型的谐振腔，降低了进气噪声的声压级。消声降噪效果明显。

Make analysis and research on air admission,using the theory design of helmhohz resonator muffler, it designs the resonant cavity which suits for some vehicle type,reduces the sound pressure level of air inlet noise,and makes obviously effect on noise exclusion and reduction.
