【摘要】 柴油机组噪声是一种环境污染源。它由多种声源构成的，主要为空气动力噪声和表面辐射噪声。在实际工作中，控制油机房噪音外泄是可行的，选择的方案是综合治理。若结合油机房结构的调整，治理工作将更加简单化。更多还原

【Abstract】 As one source of environmental pollution, diesel noise comprises multipIe sound sources, which are mainly the Aerodynamic Noise and the Surface Radiation Noise.In practice, by applying an overall treatment, it is feasible to exert control over the leakage of engine room noises. If com- bined with the structural adjustment of the engine room, the control effort would be much simplified.更多还原
