저자 : Eun-Suk Jang, Chun-Won Kang, Ho-Yang Kang, Sang-Sik Jang
초록
The sound absorption property, hand feel, air permeability and pore size of 25 kinds of traditional Korean natural wallpapers (Hanji) were measured and analyzed in this study. The sound absorption rate of Hanji became larger with increasing of frequency beginning from 3.2 kHz, reached 2 times in frequency range of nearby 4 kHz. The sound absorption rate of Hanji was increased as the permeability was lowered and the pore size was decreased. The sound absorption property of Hanji wallpaper could be improved by manufacturing process such as supercalendering process.

Keywords: Hanji wallpaper, capillary flow porometer, sound absorption rate, pore size
