STUDY ON SIMPLE ESTIMATED METHOD OF HEAVY FLOOR IMPACT SOUND CONTROL GRADE

Inside of the Housing Performance Indication System, indications related with sound environment are highly demand by residents. These affect to claim and trouble, and become civil suit factor. Therefore, to promote spreading indication of house performance are much required. In this study, focusing to the heavy floor impact sound control grade, we simplify the evaluation method criteria and proposing slab thickness grade conversion.
