sound barrier 【航空】音障,聲壘。

sound bite

Article 36 to build expressways , urban overhead road and light - tract lines that traverse areas where there are concentrated noise - sensitive structures and that might produce environmental noise pollution , sound barriers shall be erected or other effective measures shall be taken to control environmental noise pollution 第三十六條建設經過已有的噪聲敏感建筑物集中區域的高速公路和城市高架、輕軌道路,有可能造成環境噪聲污染的,應當設置聲屏障或者采取其他有效的控制環境噪聲污染的措施。

Based on the algorithm , the modeling methods of complex situations such as curved surfaces , partial absorption , directional sources , multiple sources and various sound barriers , have been presented . then , the objective modeling ( parameter prediction ) and the subjective modeling ( binaural auralization ) of enclosed sound fields have been studied in detail . in order to verify the above algorithms , the results worked out by our computer program have been compared with those of measurement in real buildings , calculating by statistical method , modeling by other researchers and a kindred software 聲場視聽一體化是在封閉聲場參數預測( parameterprediction ) 、可聽化( auralization )和可視化( visualization )基礎上提出的一個新的概念,其本質含義是:在一定的聲學、數學和信號處理理論基礎上,通過建立三維聲場的計算機模型,實現從客觀聲學指標、主觀聽覺感受和直觀視覺效果三方面對三維封閉聲場進行綜合的預測和評價。

I on the tamshui line , reducing train speed , schedule length , wheel friction and number of carriages from six to three , plus erecting more effective sound barriers along the emergent section close to minchuan west road station 新北投支線采取調降行車速度、減少班次、六車組改為三車組、車輪切削、鋼軌研磨等改善措施;民權西路站進入地下段前,增設全罩式隔音墻工程。

This phrase is borrowed from the aeronautics flight testing industry of the 1950 ’ s , when pilots flew increasingly faster , or “ pushing the envelope ” , eventually breaking through the sound barrier and further 這一個片語從1950年代的航空學飛行測試業被借,當飛行員逐漸地更快速地飛了的時候,或“推到極限“ ,最后突破健全的障礙和比較遠的。

Starting with the invention of the bicycle , going on to sports cars , cars with jet engines , rocket - powered cars , attempts to break the sound barrier , and rocket - engine airplanes 從自行車的發明開始,接著到跑車,噴氣發動機車,火箭噴射器車,試圖打破聲障,然后是火箭引擎飛機。

Approaching the sound barrier 逼近音障

It was also once said that the sound barrier would never be broken 也有人說過,牢固的障礙是無法突破的。
