Noise Evaluation Considering the Uncertainty Variation According to Frequency
Lee Chulwon(이철원),Koo SeungJun(구승준),Kong Young Mo(공영모) 한국소음진동공학회 2014 한국소음진동공학회 학술대회논문집 Vol.2014 No.4
In the evaluation of measured noise data, tolerance shall be decided based on the uncertainty. The uncertainty has frequency variations due to the different standard deviations at each frequency. Therefore, tolerance shall be differently decided for each frequency with the same confidence probability. In the report, the evaluation method considering the frequency variation of uncertainty will be introduced. From the approach, considering the actual noise distribution characteristics of the ships, the tolerance shall be decided for each frequency with the same probability, but the overall averaged value shall be kept to the value designated in each notation.
