消音器傳輸損失量測方法探討

Investigation of the Experimental Methods for the transmission loss of a motorcycle muffler

摘要


消音器噪聲分析技術中傳輸損失(Transmission Loss, TL)為一常用之聲功率等級表示法,本研究將針對雙聲源法進行探討,分別利用聲源為白噪音法與掃頻法進行實驗,並探討其不同頻帶聲壓大小與實驗結果的關係,並利用兩種方法互相驗證其準確性,得出較準確的雙聲源法傳輸損失實驗架構。

Transmission loss (TL) is a common parameter to describe the acoustic performance of a muffler. Experimental methods are studied in this research in order to establish a more accurate transmission loss measuring platform. Both white noise and swept sine method are investigated and compared to measure transmission loss by two source method.
