- Abstract
- 교사내소음영향을미치는소음은도로및철도소음을포함하며, 각음원의음향특성(주파수대역별음의높낮이등)에따라실외에서실내로전달된다. 본연구에서는실외소음이실내로전파될때전달특성의주된영향인자가실내흡음률과창호개구부면적이라고가정하였으며, 도로교통소음을대상으로실외·실내실측값과시뮬레이션을통한예측값을서로비교하여실내전달특성에대한예측기법의적정성을검토하였다. 실측데이터와예측결과의비교를통해면음원모델이점음원모델대비탁월한성능을확인하였으며, 예측오차가평균±1 dB(A) 이내로분포하는것으로나타났다. 도로및철도소음의교사내평균전달계수가-8.0, -8.2dB(A)로나타났으며, 두소음원이유사한음향특성을갖는것에기인한것으로판단된다. 본연구의결과는향후신설학교계획시환경영향평가및교육환경평가(기존학교포함)에활용될수있는유용한자료로사용될것으로기대된다.
