噪音短時間測值代替長時間測值之研討

Substituting the Short-Term Measured Value with the Long-Term Measured Value of Noise

摘要


在高雄煉油廠外圍連續測定Leq(10min)24小時,利用此結果計算Leq(10min)1次及2次與Leq(1hr)間的相關係數。所得結果其相關係數幾乎都在0.9以上,亦即爲高度相關。依此可說,在近距離同時測定連續24小時幾個測站時爲了減少人工、時間及費用,短時間測定代替長時間測定是可行的方法。

This study has continuously measured the Leq (10min) at the outskirt of the Kaohsiung Refinery of China Petroleum Company for 24 hours. The measured values are used to calculate the correlation coefficients between one Leq (10min) and Leq (1 hr), also between two Leq (10min) and Leq (1hr). The result shows that the correlation coefficient are almost above 0.9 indicating they are highly correlated. So it can be inferred that for the sake of reducing power, time and cost, the short-term measured value can substitute the long-term measured value of noise when continuously measure several locations in a close distance within 24 hours.
