  1. It introduced designs of acoustic structure of high sound insulation testing room, and applications in the field of sound - absorption, which provide reference for the professional personnel engaging noise control and architectural acoustics

    摘要介紹了高隔聲測試室的聲學結構設計及在吸聲領域的應用，以供噪聲控制和建築聲學專業人員參考。
  2. Passages reserved for connecting the engine room to the outside ( e. g., the cooling fan outlet, the exhaust outlet, the ventilation outlet, etc. ) must be designed as muffling passages, whose insertion loss should also be equivalent to the sound insulation amount of the fender structure. only in this way can the environmental noise outside the engine room live up to the standard

    為機房與外界相通而預留的通道（如冷卻風扇出口、發動機排氣出口、機房通風換氣口等）必須設計成消聲通道，其插入損失也應與圍護結構的隔聲量相當，只有這樣做才可保證機房外的環境噪聲達標。
  3. Here a number of factors must be taken into consideration, such as the environmental standard of the area where the engine room is located, the fender structure of the engine room as well as the engine type, power level and the cooling air volume, etc. the core of the overall control is the concept of " equal sound insulation ", which means to apply a closed fender structure to isolate the engine unit from outside parts so as to cut the outward sound radiation

    經過多年來與環保部門的合作，對油機房進行消噪聲處理，積累了一些治理經驗，主要是必須根據具體的機房項目來確定相應的控制方案，這其中應考慮機房所在區域的環境標準，機房圍護結構形式及油機機型、功率、冷卻風量等因素。綜合控制的核心是等隔聲概念，即用一封閉的圍護結構將機組與外界隔離開來，減少聲源對外的聲輻射。
  4. The conclusions are drawn by analysis : the sound insulation performance of structure is improved by using flexible viscoelastic materials ; otherwise it is complicated to sound insulation for incidence angles and the thickness of materials ; for multi - layered compound structure, it is important to choose flexible viscoelastic materials as external rubber, which can gain good insulative effect

    分析表明：軟質阻尼材料能明顯改善結構的隔聲性能；相對來說入射角度和材料的厚度對隔聲性能的影響比較復雜；而對于多層復合結構而言，面層橡膠的選取尤為重要，一般採用軟質橡膠材料來得到大的隔聲量。
  5. It is effective that railroad line and structure of railway carriage are improved on and acoustical absorption and sound insulation materials are selected reasonably

    改進線路狀況和車輛結構、選用隔聲、吸聲效果良好的隔聲吸聲材料是行之有效的降噪措施。
