| 摘 要： | 內燃机排气噪声是内燃机的主要噪声源。本文对产生排气噪声的机理以及声功率进行了理论探讨。在低频域,内燃机排气噪声具有简单源特性;在中、高频域,排气噪声具有四极子源特性。在频域上给出了排气噪声声功率的公式。

| Abstract: | Theoretical discussion is given to the mechanism and the sound power of exhaust noise which is the primary source of IC engine noise. v\t low frequencies, the exhaust noise shows simple-source characteristics, while at middle or high frequencies, quadrupole-source characteristics. The formulas for sound power of exhaust noise in frequency domains are given. |
