Taking into account that the technological process of surface plastic deformation during manual processing and processing on a machine tool is intensively used in various branches of mechanical engineering, it seems appropriate to study the vibroacoustic characteristics during hardening of flat workpieces, which will make it possible to achieve sanitary standards in the operator’s working area. Since ensuring safe working conditions is important in the processes of hardening slabs. This article presents the experimental results of studies of noise and vibration spectra during the processing of flat parts by the method of ball-and-rod hardening. In the course of the research, dangerous and harmful production factors that arise during the implementation of the processing of flat parts have been identified. The results of measuring sound pressure levels at the operator’s workplace during the operation of the compressor and the machine itself, as well as during the processing of flat parts, taking into account the number of indenters in the package and the preload of the hardener, are presented. The data obtained are confirmed by the correctness of theoretical conclusions about the patterns of formation of noise spectra and the contribution of noise sources to the sound field at the operator’s workplace. The research results allow us to confirm the validity of the theoretical approach to the description of the regularities of the noise generation process.
