中文摘要 | 槍砲噪音對人耳影響甚大,以往軍事單位及研發廠庫在進行訓練及測試時,均選擇人煙稀少及海岸邊進行,以避免人民反感,但隨著時代變遷及土地過度利用,使得住宅區離軍事單位及研發廠庫訓練及測試地點月來越進,槍砲噪音的改善,將成為國軍需面對的重要問題。而國內目前對槍砲噪音尚無任何規範及法令可供依循,國際間亦未達成共識,此係因槍砲噪音屬於音量極大而時間極短的瞬間脈衝音,在測量與評估上有一定難度。本文介紹目前國外對槍砲噪音之研究,並以實際量測之槍砲聲為例,以時間訊號及1/3倍頻分析來說明槍砲噪音狀況與特性,此可做為未來軍事噪音防治之參考。 |
英文摘要 | Gun blast noise has great impact to human ears. In the past, military services and weapon system research and development agencies choose remote field or coast to perform training and testing in order to reduce annoyance to the surrounding community. However, more residential areas are developed closer to these exercising areas due to the overuse of land in Taiwan. As a result, gun muzzle noise management becomes an important issue that demands immediate attention. Currently, there is no specific standard or law to regulate gun muzzle noise nor in Taiwan or international community. The difficulty of setting a common regulation is because the gun muzzle noise is an instantaneous impulse noise. In this study, we reviewed several international research results related to gun blast noise. We also illustrate an example using real measurement of time history and 1/3 octave band spectra to demonstrate gun blast noise levels and characteristics. The result of this study can be used as a reference for future work on gun blast noise management and control. |
