Usingthewell-knownbandwidthformulaandthehalfpowerbandwidthformula[R.E.D.Bishop,G.M.L.Gladwell,Aninvestigationintothetheoryofresonancetesting,PhilosophicalTransactionsoftheRoyalSocietyofLondonA255（1963）241–280],inparticular,isthesimplestwaytoestimatemodaldampingforengineers.Byusingthehalfpowerbandwidthformula,thedampingfactorisestimatedtobeapproximatelythehalfbandwidthatthehalfpowerpoints.Oneofthemajorlimitationsthatrestricttheuseofthismethodisthecouplingeffectbetweencloselyspacedmodes.Inthispaper,thedependenceofthedampingestimationaccuracyontheselectedpowerratiosisstudiedwithbothanalyticalandexperimentaldataoffrequencyresponsefunctions.Theresultsshowthatbyselectingadequatepowerratiovalues,thecouplingeffectcanbeminimizedandtheestimationaccuracycanbesignificantlyimprovedforcloselyspacedmodes.Afurtherimprovementofaccuracycanbeobtainedbyapplyingthealgorithmofmodeisolation[H.P.Yin,D.Duhamel,Substractiontechniqueandfinitedifferenceformulasformodalparameterestimation,MechanicalSystemsandSignalProcessing18（2004）1497–1503;
