| Abstract: | The vibration response of a equipment cabin in acoustic noise environment is predicated according to Statistical energy analysis(SEA)in this paper.An extrapolation formula based on past equipment cabin acoustic noise test is presented.By using mean acceleration leve(reference lg),the 19 test statistic data and test extrapolation data are comparaed,the results are satisfatory.their confidence interval are Analysed. |
