A Correlation Analysis between the Airtightness and Sound Insulation Performance on the Opening Spaces of Han-style Windows

The purpose of this study is to evaluate the correlation coefficients between the airtightness and sound insulation performance of Han-style windows in New Han-ok. To achieve these goals, field measurements were accomplished in 18 bedrooms of 16 Han-oks in which actual residents were living, and then lab measurements were proceeded in the reverberation lab for evaluating the sound insulation performance. Followings are results. The results of the correlation analysis between the airtightness(Air change per hour at 50 Pa, ACH50) and sound insulation performance(Sound reduction index, Rw) in bedrooms of actual Han-oks, it was found that there were no significant correlation between two evaluating values. On the other hand, it was analyzed that the correlation coefficients of total 24 structures(double casement windows, single casement window, casement and sliding windows, single sliding window, 6 types per each structure) were located on 0.6757 exponentially and 0.4154 lineary in the lab evaluating conditions. But, The results of evaluating 4 structure classificatorily, it was found that there were high correlation coefficients(0.8665~0.9273 at ACH50, 0.8414~0.9346 at Rw). These results were signified that the correlation coefficients were changed according to the each structure and case by case analysis were necessary at the same time. c 2014 KIEAE Journal 한식창호, 기밀성능, 시간당 환기회수, 차음성능, 음향 감쇠 계수 Han-style Windows, Airtightness Performance, Air Change per Hour at 50pa, Sound Insulation Performance, Sound Reduction Index A C C E P TA N C E IN F O Received April 21, 2014 Final revision received June 21, 2014 Accepted June 23, 2014 한식 창호의 개구 면적에 따른 기밀 및 차음 성능간 상관성 연구 88 KIEAE Journal, Vol. 14, No. 3, Jun. 2014 따라서, 본 연구에서는 신한옥 내외부간 침기와 소음 프라이버시 에 큰 영향을 미치는 한식 창호를 대상으로 한 기밀성능 및 차음성능 을 실시하여 각 성능간 상관성 분석을 통해 기밀성능 평가량 변화에 따른 차음성능 평가량 변화 추이를 분석해 보고 향후 한식 창호 성능 향상에 필요한 자료를 제공하고자 한다.
