| Abstract: | According to "Guide to the Expression of Uncertainty in Measurement" and "the Evaluation and Expression of Uncertainty in Measurement" , this paper discussed and estimated the cumulative effects of all causes (not include the affect of sound source) of measurement uncertainty in I. C. engine sound power level measurement. It aimed at improving the precision of the result of noise measurement , promoting the study of reducing I. C. engine noise and making measuring uncertainty widely used in the I. C. engine industry. |
