摘要：
The invention relates to techniques for listening to the closed cavities of various objects to diagnose their condition. It can be used in medicine to study the noise of the human body, in technology for assessing the state of various mechanisms. The technical task of the invention is to simplify the design, obtain better sound information and improve reliability. The device of the sound stream compactor for auscultation contains a parabolic reflector, in which the central hole, and a reduced parabolic reflector is installed in its focus. The focus of the parabolic reflector and the focus of the reduced parabolic reflector are the same. The reduced parabolic reflector and the central hole have the same diameters. The central hole in the parabolic reflector is connected to a flexible tubular sound pipe equipped with an ear tip. The technical result from the application of the present invention is due to the fact that the design of the device is simplified and, accordingly, its reliability is increased, since there are no power sources and electronic devices. The received sound information is better, due to the fact that the picture of the sound stream coming from the object of study is not distorted in the singular region, but is compressed and unambiguously reflected from the surface of the reduced parabolic reflector, because the sound stream becomes more intense as a result of its compression.Изобретение относится к технике прослушивания закрытых полостей различных объектов для диагностирования их состояния. Может быть использовано в медицине для изучения шумов жизнедеятельности организма человека, в технике для оценки состояния различных механизмов.Технической задачей предлагаемого изобретения является упрощение конструкции, получение более качественной звуковой информации и повышения надежности.Устройство уплотнителя звукового потока для аускультации содержит параболический отражатель, в котором выполнено центральное отверстие, а в его фокусе установлен уменьшен
