Abstract
Изобретение относитс к измерению звуковых колебаний, з частности к устройствам дл оценки звукоизолирующих свойств конструкций. Дл расширени эксплуатационных возможностей устройства и повышени точности результатов в устройстве каждый внешний излучатель шума 8-11, установленный вокруг исследуемой объемной конструкции, разделен экранами 13-16, выполненными из металлических листов, покрытых с двух сторон последовательно сло ми вмбродемпфирующего материала и эластичного звукоизолирующего материала с открытыми наружными попами, а угол распространени направленных звуковых волн, излучаемых каждым внешним излучателем шумз, меньше угла, создаваемого этими излучател ми и наружными торцами соответствующих экранов. Между ребрами исследуемой конструкции и торцами экранов установлены уплотнители, выполненные из упом нутого звукоизолирующего материала. 3 ил.The invention relates to the measurement of sound vibrations, in particular, to devices for evaluating the sound insulation properties of structures. In order to expand the operational capabilities of the device and increase the accuracy of the results in the device, each external noise emitter 8-11, mounted around the investigated volumetric structure, is divided by screens 13-16, made of metal sheets, covered on both sides in succession by layers of vibration damping material and elastic soundproof material open outside popes, and the angle of propagation of directional sound waves emitted by each external noise emitter is smaller than the angle produced by these and The routers and outer ends of the corresponding screens. Between the ribs of the structure under study and the ends of the screens, there are seals made of the said sound-insulating material. 3 il.
