摘要
用凸分析理论分析了机器噪声测试中平均声强级近似计算的误差 ,导出了最大误差计算公式 。
In this paper the approximate calculation error of average sound intensity level is discussed by means of convex theory.The maximum error calculation formula is established.This paper pointed out the condition of maximum error when the approximate formula was used in measuring noise of automobile engine.
