AN EXPERIMENTAL STUDY ON MEASUREMENT OF SOUND INSULATION OF LIGHT WEIGHT WALL WITH LOESS BOARD USED IN KOREAN TRADITIONAL HOUSE(HAN-OK)

摘要

The purpose of this study is to evaluate residential performance of Korean traditional house(Han-ok) by comparing sound insulation performance of lightweight wall finished with the existing gypsum board and loess board developed with loess, Korean traditional house finishing material. The measurement of sound insulation performance was performed by test method of international standards, ISO 140-3 and ISO 717-1. The results of measurement showed that sound insulation performance of loess is better than that of gypsum board, and that all specimens applying only loess showed Grade 2 while those specimens applying only gypsum board of sound insulation grades presented by Korean building regulations indicated 'out of grade'.
