The end linking the timing gears cap, the side wall of cylinder and the skirt section of the engineblock are the sound radiation resources of the two engineblock sides. Except that, this thesis calculates sound power level of radiated noise from the engineblock with MATV method. It is found that the noise radiated from the engineblock is slightly loud.

此外本文还应用MATV法计算了气缸体辐射噪声的声功率级，通过声功率级的计算发现：气缸体的辐射噪声偏高，达到了108.84dBA，并且在850Hz时，由于气缸体的激励频率与其第八阶固有频率相等，气缸体发生了共振，因而在该频率时，气缸体的辐射噪声最大，所占气缸体表面辐射噪声总能量比重也最高，该频率应该是本文噪声控制关心的重点。
