Sound barrier capable of reducing sound energy losses
The invention provides a sound barrier capable of reducing sound energy losses. The sound barrier capable of reducing the sound energy losses comprises a rectangular slot, a protective connecting rodand a bracket, the rectangular slot is made of hollow sound insulation steel plates, two ends of the rectangular slot are sealed, a flange which is in flange connection with a dock wall surface is welded to one end of the rectangular slot, connecting circular rings are symmetrically fixed to two side edges of the rectangular slot, circular rings are arranged at two ends of the protective connecting rod, the circular ring at one of the two ends of the connecting rod is connected with the connecting circular rings of the rectangular slot, the circular ring at the other end of the connecting rodis connected with the dock wall surface, and the bracket is fixed to the dock wall and supported under the rectangular slot. The sound barrier capable of reducing the sound energy losses is suitable for reflecting back sound waves from the side when a reverberation method is used for measuring the sound power of ships in a dock pool, the sound energy leakage in the dock pool is reduced, the signal-to-noise ratio in the dock pool is improved, the sound field diffusivity is improved, and the accuracy of the measurement of the radiated sound power of the ships in the dock pool is improved.
本发明提供的是一种减少声能损耗的声屏障。包括矩型槽、保护连杆以及支架，所述矩型槽由中空隔声钢板制成，矩型槽两端密封，矩型槽一端焊接有与船坞壁面法兰连接的法兰，矩型槽两个侧边对称固定有连接圆环，所述的保护连杆两头带有圆环，连杆一头的圆环与矩型槽的连接圆环连接，连杆另一头的圆环与船坞壁面连接，所述支架固定于船坞墙壁上支撑在矩型槽下。本发明适用于在船坞水池中使用混响法测量舰船声功率时采用该声屏障装置把侧面来的声波反射回去，减少船坞水池中的声能泄露，提高船坞水池中的信噪比，增强声场扩散性，提高船坞水池中舰船辐射声功率测量的准确性。
