摘要
摘要本文论述了表面声强法及其在混响条件下的应用,探讨了运用自谱表面声强新方法在数据处理及测试技术中的一些有益经验,并通过与其它方法的比较论证了它的可行性.
Surface acoustic intensity technique and its application in measurement of engine sound power under condition of reverberation, including test data reduction using autospectrum and beneficial experiences in testing, were described. Feasibility of the new technique was validated through comparison with other techniques.
