Waterpower Generation is the pollution-free clean energy that produces electric power using water pressure, and on account of its merit that contributes to supply the superior quality of electricity, its regular construction had been promoted together with the Five-year Plan for Economic Development in 1960s. However, since the Noise which was made during the operation time of the hydraulic turbine dynamo should be inevitably exposed directly to the adjacent office, it brings many inconveniences to the business, and because the dynamo room locating between the hydraulic turbine dynamo and the office was architecturally concluded with the reflection material-centered, it functions rather to amplify the Noise that occurs during the operation time of the hydraulic turbine dynamo. Therefore, this Study has actually surveyed also evaluated the architectural acoustic characteristics of the hydraulic turbine dynamo room on the subject of Daechung Dam. It is now considering that such material could be utilized as the valuable data hereafter in control the Noise of the hydraulic turbine dynamo room.

In case of College Art Hall that was made for their rehearsal or public performance or so for Art College Students, this necessitates more of countermeasure for sound-insulation also soundproof than other common buildings. However, without any accurate classification between Sound-Insulation and Sound-Absorption, most of them recognizes that if merely the sound-absorption material is used thereat, the transmitting sound into the adjacent chamber can be intercepted, so that it is the actual circumstances that they prepare the countermeasure for Sound-Absorption only. Accordingly, due to such imprudent measures, those sounds and voices which performing at the neighboring room are travelling to the exercise room, a lot of difficulties should be suffered when they exercise. This Research has measured the sound-insulation characteristics in accordance with its existence or nonexistence of the 'opening' on wall-body for the object of various wall-bodies in recently built College Art Hall, and on the basis of the above, this Study willing to present a fundamental data for establishment an efficient sound-insulation measures, by comparison and evaluation with the standard table on boundary-noise, domestically on current.
