| Abstract |
On-dol, which is a Korean traditional heating system, is in use to this day because the system is suitableto our lifestyle. And nowadays, for the reduction of construction period and enhancement of productivity transitionfrom existing system to dry type On-dol system has been attempted. However, dry type On-dol system was not putto practical use because of the restrictions of thermal and acoustic performance, construction workability and economicproblem. Especially, restriction of acoustic performance is an essential problem in apartment buildings. Therefore, thispaper presents data for reduction of floor impact noise by comparison and analysis of existing system and On-dolsystem through field measurement. |
