With　the　industry　development,　people　are　raised　higher　and　higher　noise　and　vibration　comfort　requirements,　which　initiated　material　company　developing　higher　sound　isolated　material.　In　this　paper,　a　new　laminated　glass　sample　from　DuPont　is　investigated　by　using　numerical　models.　Based　on　the　analysis　frequency　and　damping　requirements　from　Dupont,　LMS　Virtual.　Lab　Finite　Element　Vibro-Acoustic　Solver　and　Inter　A.C　Statistical　Energy　Analysis　solver　are　both　preferred　for　covering　the　full　frequency　band　and　considering　the　frequency　dependent　damping　through　damping　loss　factor　definition.　Based　on　these　two　numerical　models,　the　laminated　glass　sample　material　Transmission　Loss　(TL)　performance　is　investigated　with　these　numerical　models;　Comparing　with　the　test　data　from　DuPont,　both　models　shows　very　good　results,　SEA　model　is　much　more　faster　than　FEA　Model　which　can　be　used　during　the　product　concept　design　phase,　but　FEA　model　is　much　more　accurate　and　good　at　for　capturing　the　damping　effect　which　can　be　used　for　product　detail　design　and　material　basic　research.　The　authors　also　present　details　related　to　the　numerical　models.
