Chinese Abstract

在台灣居高不下的都市噪音環境,室內為求隔絕戶外噪音而裝設氣密隔音窗,卻因此阻礙了室內外的自然換氣,不但使室內空氣品質變壞,也增加了室內冷氣的負荷。因此本研究進行窗用消音器與氣密隔音窗整合之研究,嘗試平衡隔音與換氣兩者性能,希望在隔音窗下實現既能換氣又能消音減噪之換氣隔音窗設計。本研究於國立成功大學建築系聲學實驗室,利用聲強法量測其隔音性能,分析本研究設計之四種吸音裝置型式,即空殼式、微孔吸音板式、穿孔板內填玻璃棉式以及共振腔式,依實驗結果在風扇運轉的換氣狀態下,共振腔設計型式之換氣隔音窗不僅能滿足通風需求,而隔音性能亦可達到R_W=32dB,研究成果除符合研究目標外,並可提供給業界之參考,協助廠商提升研發換氣隔音窗之技術能力。

English Abstract

Installing soundproof windows for isolation from outdoor noise also obstructs fresh air flow. It causes bad indoor air quality. This research conducted tests of many kinds of ventilated silencers for soundproof windows to try to combine sound insulation and ventilation performance in one window system. The present study analyzes sound insulation with respect to ventilation effects, the object being to develop window systems that will reduce noise transmission whilst allowing airflow into the building, a performance that matches summer indoor ventilation and refreshment needs. In addition these window systems will enable the efficient use of daylight, thus addressing growing concerns about sustainability. In this study at the Acoustics Laboratory various prototypes were tested and their acoustic performances were assessed by types of ventilated silencers. The results show types of variable-volume resonant silencers have values over 32dB by R_w index, showing excellent acoustic performances, and the results show that the proposed method can achieve the design goal of obtaining high-performance sound insulation on ventilated soundproof windows in buildings.
