The case of the subject gymnasium, since the finishing materials of strong reflectivity were mostly used, due to the declines of its vibration, reverberation and clearness, the serious acoustic defects are arising. Thence based on the study result that researched at the precedent study, this study has attempted to examine the acoustic satisfaction degree as well as its reaction by conduct an auralizational experiment and as the result, because the acoustic performance of the subject small-scaled gymnasium was upwardly appraised. It is considering that such result of the study could be utilized as the useful material which maintains the curtailment effect of construction cost also enables to elevate the acoustic performance when construction of the similar gymnasium henceforth, by means of presupposition·control the acoustic problem from its designing stage.

Opera House of Seoul Arts Center was opened in 1993, and is currently Korean representative opera house in connection with size and architectural shape resembling "Katmuri (one of radical components of Chinese characters)". However, due to fire during performance in December, 2007, remodelling was conducted, and so, finishing materials and interior factors including auditorium, wall and proscenium arch were changed, and acoustic performance was improved. In precedent studies, physical acoustic performance of opera house was assessed through acoustic simulation, and optimal improvement scheme was suggested, and acoustic performance was assessed through actual measurement on the spot after completion of remodelling. However, good results of physical acoustic performance don't necessarily mean good performance of acoustic performance felt by audience. Therefore, Physical and subjective acoustic Performance should be simultaneously assessed to assess acoustic performance of performance hall. From this viewpoint, this paper aims to assess subjective acoustic performance by conducting auralization experiment through which virtual acoustic field may be experienced at the stage of design after conducting optimal acoustic design through computer simulation on. After that, through the actual measurement after the Opera House of Seoul Arts Center was completed, the thesis investigated the characteristics of room acoustic and examined the reliability if it was constructed suitably for acoustic simulation. Also, the paper figured out the ordinary people's satisfaction of acoustic efficiency through psycho-acoustic experiment in the actual site.

리모델링을 통한 예술의 전당 오페라 극장의 건축음향 성능 개선에 관한 연구
박영지(Park Yeong-Ji),이국현(Lee Kook-Hyun),김재수(Kim Jae-Soo) 대한건축학회 2009 대한건축학회논문집 Vol.25 No.10
Opera Theater of Seoul Arts Center opened in 1993 is the opera-house representing our Country in the respects of the peculiar architectural form and its scale, with the shape symbolizing "Gatmouri"(Mount Ridge Beam). However, by passing 16 years sinceits construction, the facility has been gradually superannuated, and due to the fire broke out during the public performance in December, 2007, a necessity to do remodelling on the most of inside interiors had been arisen. Accordingly, in order to improve the acoustic characteristics of the Opera Theater, this Study has proposed the Change of Form and Finishing Materials on the spectator-seat, wall, Proscenium Arch using the Computer Simulation of Odeon 4.21 after a sound fault grasp of opera theater, at its remodelling stage. Likewise, at the Opera Theater newly constructed based on the suggested design materials, as the result of evaluation on the characteristics after conduct an actual survey on the acoustic performance using the symponie, the micro phhone and the DAT recorder prior to its Opening, it could be known that the acoustic performance was maintaining on more suitable acoustic condition of SPL, RT, D??, C??, Echo to the Opera Theater after remodelling work than the initial construction.

Although the college gymnasium was the space for students' education and athletic activity only, but in accordance with development of the society, recently its utilization is gradually expanding as a cultural space for the local citizens. However, since most of the old-aged gymnasium was constructed without consideration on the architectural acoustic characteristic that enables to accept diversified purposes. In case of the subject gymnasium, as the finishing materials of broad volume and strong reflectivity were used, a serious acoustic defects whereupon in order to control the vibration state and raise up its clearness, it is urgent situation that optimizing method of the acoustic factor. On such point of view, this study has small-scaled gymnasium where the acoustic defect is arising, and has grasped its architectural acoustic characteristics, then on the basis of this, also compared · analyzed both acoustic characteristics between the surveyed value of before-improvement and the predicted value of after-improvement using acoustic simulation. As a result, at after improvement comparing with before improvement, the purpose of the sports facility together with its function as a multipurpose space with possibility of various public performances have been evaluated as suitable. It is considered that such data could be utilized as the quite useful material for improvement the acoustic performance of the similar gymnasium hereafter at its designing and constructing stage.

도로교통소음으로 인한 박물관 전시실의 실내 소음레벨 예측 및 평가
이국현(Kook Hyun Lee),박영지(Yeong Ji Park),김재수(Jae Soo Kim) 大韓環境工學會 2010 대한환경공학회지 Vol.32 No.8
최근 자동차 보급률과 물동량의 급증으로 인해 도심에서 교통소음은 정온함을 목적으로 하는 전시 및 관람시설의 음 환경을 저해하는 중요한 인자로 대두되고 있으며, 이에 따른 불만족이 매우 높은 편이다. 따라서 전시 및 관람시설의 경우 설계단계에서부터 교통소음에 대한 영향평가를 실시하여 전시실 내외부의 소음에 대한 만족 여부를 파악해야 한다. 그러나 설계단계에 있는 건축물의 경우 교통소음으로 인한 실내소음레벨을 측정할 수 없어, 지금까지는 질량법칙을 토대로 한 벽체의 투과손실 식을 사용하여 예측하고 있다. 그러나 실제 건립 후 실내 소음레벨을 측정해 보면 설계단계와는 많은 차이를 보이고 있어 개관 후 이에 대한 대책 마련에 많은 어려움이 있다. 이러한 관점에서 본 연구에서는 고속도로에 인접한 민속박물관 전시실의 실내소음도 평가를 위해 실측한 자료를 토대로 차음벽체의 투과손실과 음향시뮬레이션을 이용한 실내흡음력을 산정하여 실내 소음레벨을 예측 평가해 보았다. 이러한 연구결과는 향후 이와 비슷한 전시시설 건립 시 실내소음도의 예측을 위한 중요한 자료를 제공할 것으로 판단된다. Recently, with sudden increase of supplying rate of cars and quantity of goods transported, traffic noisy becomes one of important factors obstruct environment of exhibition and view facilities have purpose in calmness and unsatisfaction about this is high now. Therefore, in case of exhibition and view facilities, it has to be grasped that satisfaction degree about the noisy in and out of the exhibition room by performing effect valuation on traffic noisy from design step. However the level of internal noise cannot be measured at the design phrase of the structure due to the noise of traffic. Up until now a walls transmission loss, based on the law of mass, is predicted using this method. However measuring the internal sound level after actual construction reveals that there is a large difference from measurements made at the design stage, and it is very difficult to find a solution after the opening of the structure. From research looking from this perspective the internal sound level was predicted- calculating the internal sound absorption ability, using acoustic simulation and loss prevention of an insulated wall- based on data collected to evaluate the internal sound of an exhibition room at a Folk Museum adjacent to a freeway. The results of this research are considered to provide important data for the prediction of internal sound level at the time of construction of exhibition facilities similar to this.
