Introduction: The article deals with the issues of protection against noise and vibrations of engineering equipment, which spread into the residential area through ventilation shafts, and the problems of bringing noise to standards during the operation of diesel generators. The purpose of this work was the development and implementation of methods and means to reduce the vibration levels of the walls of the technological room in which the diesel generator set was installed. Materials and Methods: The article presents studies using computational and graphical and resonance and statistical methods. Measurements of the noise level from the operation of a diesel generator located on the site of the residential buildings under consideration, as well as in residential premises, were carried out. Results and Discussion: The estimated calculation showed that the noise levels on the territory do not meet the requirements of sanitary standards. The results of measurements of the sound pressure level before and after noise protection measures for an individual living space gave an assessment of the qualitative and quantitative ratio of the accepted and new types of measures and materials. Conclusions: The effectiveness of vibration isolation of engineering equipment depends on the applied vibration isolation scheme; the wrong choice of vibration isolation scheme can lead to an uncontrolled increase in the amplitude of vibrations of the foundation of engineering equipment. To eliminate low frequencies, it is necessary to install vibration isolating supports under the foundation of the diesel generator set.
