The case study for this research is a middle school music room located in Iksan City, Korea. Although the room is used for teaching music, indiscreet sound-absorbing materials were applied within the space. Accordingly, a number of difficulties have been experienced when using the room. During a music lesson, the sound-volume is inadequate for music appreciation, while the music performance has an arid sound due to an insufficient echo. In order to control the obstructive factors resulting from a short Reverberation Time, the acoustic factor is optimized in this study by using an Acoustic Simulation, following an arrangement of Acoustic Design. A Psycho-acoustics Experiment was conducted using the Auralizational Technique, whereby the Virtual Acoustic Field can be experienced at the design stage.

It has been noted, in case of the apartments in collective form, the drainage noise from cleaning of toilet causes many problems in the basement and adjacent rooms, mainly hampering the pleasant housing environment. The problems are increasingly raised by civil complaints with the public offices. Therefore, if the drainage noise generates when wash out of toilet bowl is grasped how the characteristics change according to the sorts of drainpipe, it is considered that the establishment of an effective sound insulation countermeasure could be possible when a civil petition against the drainage noise of apartment house is submitted hereafter. On such viewpoint, this study measured and analyzed the characteristics of drainage noise per the type of drainage pipe, according to KS A ISO 1996-1~3, with the horizontal branch pipe and riser pipes in the drainage noise experiment chamber which has the characteristics of the anechoic room. In the result, the pipe type with excellent noise reduction function. The result of this study is considered to become available as fundamental data, to take actions on reduction of drainage noise of the ceiling piping method.

Multipurpose Dam, it produces electric energy by converting the potential energy into kinetic energy utilizing its head and quantity of the water. However, in this process, since during the time when the turbine connected to the hydraulic turbine generator revolves, there occurs a ceaseless loud noise, and due to this condition, it is true state that those people who work at inside of the power plant are damaging as hard as they are unable to concentrate on their work. Not only this, because the hydro-electric power generator room that locates at middle section between the hydraulic turbine room and the office is very large space volume, also since it was constructed chiefly by the reflecting material, it is functioning of amplify the noise when operating the generator, the soundproof measure against this condition is necessitated. On such viewpoint, I have presented the problem point of the relevant Hydraulic turbine dynamo and Hydraulic turbine dynamo room, and after improve such problem point, this study has ever investigated the satisfying degree about the noise-reduction at before and after of the improvement of soundproof measure, using the Auralizational technique that can experience virtual acoustic field. It is considering that such result could be utilized usefully as the fundamental material hereafter for the acoustic performance of the hydro-electric power generator room in dam and when its construction.

대학 기숙사의 기계실에서 발생하는 설비소음의 특성에 관한 연구
박정호(Park Jung-ho),김평석(Kim Pyung-suk),설수환(Soul Soo-hwan),곽광수(Kwak Kwang-soo),김재수(Kim Jae-soo) 대한건축학회 2003 대한건축학회 학술발표대회 논문집 - 계획계/구조계 Vol.23 No.2
Machine room Packed with various machinery are one of the greatest sources of noise. Noise made by a machine room is transmitted to residential spaces as air-borne sound as well as. disturbing residents' pleasant living environment and causing public complaints. In addition. many buildings that were constructed without full consideration of soundproofing in design issues need to be repaired to control noise at high costs. Therefore. the purpose of this study is to provide basic information for establishing consideration against noise from machine rooms. by measuring and analyzing noise made by machinery in the machine room of dormitories at J. W and H University which had different characteristics.
