Research results of the part surface treatment by a ball-and-rod reinforcer (multicontact shock-vibrating tool) through the surface plastic deformation method are provided. The considered process can be used for hardening both flat and curved surfaces, as well as for generating compressing residual voltages, pocket smoothing, regular microrelief fitting on friction pairs, and for joint weld machining. When carrying out this research, the manufacturing processability is identified, the regularities of selecting design data of the device are determined. The treatment process is percussive, and it is attended by heavy acoustic radiation. It is found that noise under processing far exceeds the allowable range. Materials and Methods. The investigation was conducted on a universal milling machine. Long flat parts were exposed to hardening. The parts were installed directly on the machine table or in special devices. A line noise source was accepted as a model. Research Results. Dependences are obtained for determining the sound pressure, natural frequencies of the part oscillations, and noise spectra. A set of noise abatement procedures under processing is worked out. A considerable amount of the experimental research confirming adequacy of the obtained theoretical models is undertaken. Discussion and Conclusions. When carrying out the studies, it is established that efficiency in noise abatement cannot be obtained by the rational selection of the vibration-absorbing material. In this regard, the use of passive noise protection of the machine site in the form of a flat polycarbonate-glass screen is recommended. This will allow reducing noise in the work zone to the standard values. Design data of the offered acoustic screen are calculated.</p></abstract><trans-abstract xml:lang="ru"><p>Введение. В статье представлены результаты исследований обработки поверхностей деталей шарико-стержневым упрочнителем (многоконтактный виброударный инструмент) методом поверхностно-пластического деформирования. Рассматриваемый процесс может использоваться для упрочнения как плоских, так и лекальных поверхностей, создания сжимающих остаточных напряжений, сглаживания каверн, нанесения регулярного микрорельефа на пары трения, а также для обработки сварных швов. При проведении настоящих исследований выявлены технологические возможности обработки, определены закономерности выбора конструктивных параметров устройства. Процесс обработки относится к ударным и сопровождается интенсивным звуковым излучением. Установлено, что шум при обработке значительно превышает допустимые пределы. Материалы и методы. Исследования проводились на универсальном фрезерном станке. Упрочнению подвергались длинномерные плоские детали, которые устанавливались непосредственно на стол станка либо в специальные приспособления. Линейный источник шума принят в качестве модели. Результаты исследования. Получены зависимости для определения звукового давления, собственных частот колебаний детали и спектров шума. Разработан комплекс мероприятий по снижению шума при обработке. Выполнен значительный объем экспериментальных исследований, подтверждающий адекватность полученных теоретических моделей. Обсуждение и заключения. При проведении исследований установлено, что эффективность в снижении шума не может быть достигнута рациональным подбором вибропоглощающего материала. В связи с этим рекомендуется применение пассивной шумозащиты рабочей зоны станка в виде плоского экрана из поликарбонатного стекла, что позволит довести до нормативных значения шума в зоне обработки. Рассчитаны конструктивные параметры предлагаемого акустического экрана.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>обработка шарико-стержневым упрочнителем</kwd><kwd>уровни звукового давления</kwd><kwd>спектры шума</kwd><kwd>защитные устройства</kwd><kwd>processing through ball-and-rod reinforcement</kwd><kwd>sound pressure levels</kwd><kwd>noise spectra</kwd><kwd>protection devices</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Чукарин, А.
