Recently, the expectation of people about the comfort of sound is higher than the past. But the current noise assessment at ground noise cannot reflect it. This study was conducted about complex design element, which is compared by ground noise. Indexes about complex design element were determined that CR(Cover Ratio), DR(Depth Ratio), BR(Building-dep. Ratio) and EAR(Exceed Area Ratio) and were compared with the ground average Sound Pressure Level(SPL). The simulation result was compared with indexes by correlation analysis. Consequently, CR, DR, GR and EAR showed a tendency to be proportional or inversely proportional with the average Sound Pressure Level(SPL) in ground.
