摘要
建立了一个统计能量分析 (SEA)模型用于轿车内室噪声的仿真计算 .40 0～ 5 0 0 0Hz频率范围内SEA模型的计算结果与车内声压水平实测值的误差达到 3dB以内 .基于此模型进行了轿车内室噪声的优化与控制研究 ,获得一系列有价值的分析结果 .
A statistical energy analysis(SEA) model was developed to simulate the interior noise of car.The interior car sound pressure level results of the SEA model obtain a difference of less than 3 dB compared to the test data over the frequency range of 400～5 000 Hz.Some methods of car interior noise controlling and optimization were analyzed based on this model to obtain a serial of valuable results.
