The purpose of this study was to establish structural bone noise analysing method for apartments building floor with Structural-Acoustic coupling analysis. Nowadays, noise through floor is recognized as important problem with the consequence that noise isolation technique is studied in the various fields of industry. From among noise factors, resonance sound is main reason for floor's solid noise. therefore, In this study, evaluation method for composite material slab is established and that a case study is suggested with it.
