摘要
建立了一个统计能量分析 (SEA)模型用以轿车内室噪声的仿真计算 .结果表明 40 0～ 5 0 0 0Hz频率范围内的空气噪声和固体噪声都适用于统计能量分析方法 .SEA模型的计算与车内声压水平实测值精度在主要频带达到 3dB以内 .
A statistical energy analysis (SEA) model was developed to simulate the interior noise of cars.The result indicates that both ari-borne and structure-borne noise over the frequency range of 400～5 000 Hz was able to be considered using the SEA method.The interior car SPL results of the SEA model obtain a differentce of less than 3 dB compared to the test data.
