齿轮单元(变速箱)的噪声排放既取决于干扰(齿轮啮合、轴承运行等)，也取决于外壳的绝缘能力和模态行为。根据设计参数，可以防止或增强壳体墙壁的自然振动。传输噪声的激励和发射机制是通过执行激励能量通过功率发射器结构的传播过程和通过壳体的模态测试来确定的。振动和噪声测试结果与模态测试结果的比较，为所选变速箱的噪声结构识别提供了可能性。对获得的结果进行比较和分析，可以准确地确定齿轮传动单元总谱的产生原因。
The noise emission of gear units (gearboxes) depends both on the disturbances (gear meshing, bearing operation, etc) and on the insulating capabilities and modal behavior of the housing. Natural vibrations of the housing walls can be prevented or intensified depending on design parameters. The mechanism of exciting and emission of transmission noise is defined by carrying out the process of propagation of excitation energy through the structure of power transmitters and by modal testing of the housing. The results of vibration and noise testing in comparison to the results of modal testing give the possibility of identification of noise structure for the chosen gearbox. Comparison and analysis of the results obtained lead to precise determination of the causes of creation of the total spectrum of gear transmission units.
