Выявление повышенных шумов от вентиляционных систем в период эксплуатации зданий приводит к необходимости проведения сложных и дорогостоящих операций по обнаружению и устранению источников шума, проведению демонтажных работ, установке дополнительных шумоглушителей или замене вентиляционного оборудования. Проведение корректных акустических расчетов является одной из важнейших задач при проектировании объектов различного назначения. Метод. В статье представлен анализ отечественных и зарубежных методик по определению шума, генерируемым дросселирующим устройством. Оценка точности результатов расчетов проводилась с помощью их сравнения с данными натурных испытаний. Результат. Было выявлено резкое возрастание уровня звуковой мощности в дросселирующем устройстве при увеличении угла поворота створки более 60 градусов, что оказывает значительное влияние на акустическую обстановку помещений и приводит к превышению нормируемых уровней шумового воздействия. Вывод. Проведенный сравнительный анализ существующих методик расчета позволил выявить, что отечественная методика расчета дает требуемый запас по уровню звуковой мощности дросселирующего устройства по всем октавным полосам. К недостаткам зарубежных методик расчета можно также отнести отсутствие учета акустического влияния фасонных элементов и присоединения воздуховода к дросселю, что приводит к необходимости дальнейшей верификации методик расчета для сложных систем.</p></abstract><trans-abstract xml:lang="en"><p>Objective. The identification of increased noise levels from ventilation systems during the operation of buildings necessitates complex and costly procedures to detect and eliminate noise sources, conduct dismantling work, install additional silencers, or replace ventilation equipment. Therefore, accurate acoustic calculations are one of the most critical tasks in the design of various facilities. Method. This article presents an analysis of domestic and international methods for determining the noise generated by throttling devices. The accuracy of the calculation results was evaluated by comparing them with data from field tests. Result. A sharp increase in sound power level within the throttling device was observed when the blade angle exceeded 60 degrees, significantly impacting the acoustic environment of the premises and leading to an exceedance of regulated noise levels. Conclusion. The conducted comparative analysis of existing calculation methods revealed that the domestic calculation method provides the required margin for the sound power level of the throttling device across all octave bands. A notable drawback of international calculation methods is the lack of consideration for the acoustic impact of duct fittings and the connection of the duct to the throttle, which underscores the need for further validation of these methods for complex systems.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>шум</kwd><kwd>шумовые характеристики</kwd><kwd>вентиляционная система</kwd><kwd>дросселирующие устройства</kwd><kwd>уровень звуковой мощности</kwd></kwd-group><kwd-group xml:lang="en"><kwd>noise</kwd><kwd>noise characteristics</kwd><kwd>ventilation system</kwd><kwd>throttling devices</kwd><kwd>sound power level</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">Лешко М.Ю.
