Abstract: PURPOSE: An anechoic performance inspecting device and an anechoic performance measuring system using the same are provided to measure the performance when an inspection object is within a same medium or becomes a boundary of media different each other. CONSTITUTION: An anechoic performance inspecting device comprises a first body unit(100), a second body unit(200), a specimen fixing unit(300), a signal generating unit, and a signal sensing unit. A fluid is charged in an internal space of the first body unit. One end of the second body unit is joined to the first body unit. The second body unit is connected to the first body unit. The fluid is charged in an internal space of the second body unit. The specimen fixing unit is joined to one end of the first body unit. The specimen fixing unit fixes a specimen to be positioned in the internal space of the first or second body unit. The signal generating unit released continuous or discontinuous signals to the internal space of the first or second body unit. The signal sensing unit senses the signals existing in the internal spaces of the first and second body units.
Abstract translation: 目的：提供一种消声性能检测装置和使用该检测装置的消声性能测量系统，以便在检查对象在同一介质内或成为彼此不同的介质边界时测量性能。 构成：消声性能检查装置包括第一主体单元（100），第二主体单元（200），样本固定单元（300），信号生成单元和信号感测单元。 流体在第一主体单元的内部空间中被充电。 第二主体单元的一端连接到第一主体单元。 第二主体单元连接到第一主体单元。 流体在第二主体单元的内部空间中充电。 样本固定单元连接到第一主体单元的一端。 样本固定单元将要定位在第一或第二主体单元的内部空间中的样本固定。 信号发生单元将连续或不连续的信号释放到第一或第二主体单元的内部空间。 信号感测单元感测存在于第一和第二身体单元的内部空间中的信号。
