In this study, an analysis is carried out on the acoustic design for an indoor gymnasium scheduled to be built at Buan County, Chonbuk Province. By way of background, the study examines the case of a large-scale indoor gymnasium that has been constructed in the local area of Hangan-myeon. There are many examples whereby this gymnasium could be used not only as a sporting facility for the residents, but also as a multipurpose space for public performances such as leisure activities, lectures, assembling activities, theatre and concerts etc. In order to maximize the functional utilization of such an indoor gymnasium, it is important to simultaneously verify the acoustic capabilities of the space in terms of Definition of both Voice and Music. However, as a large-scaled athletic facility, the building was designed with a high ceiling-height to accommodate its functional characteristics. The space forms a Sound Focus whereby the sound is concentrated at a specific part, and because the vibration of sound is too loud due to its broad volume, acoustic defects arise such as a significant number of Echoes. Using this gymnasium as a precedent, this study proposes an acoustic design based on the drawings of the indoor gymnasium that is scheduled to be built at B County, Chonbuk Province. The gymnasium is equipped with an optimized acoustic condition passing through the Acoustic Simulation Phase. From the results of an Acoustic Simulation, we can design an indoor gymnasium that is equipped with a considerably satisfying and improved acoustic performance compared with the building before it was reformed. It is also considered that the use of such materials can fundamentally reduce construction costs and can improve acoustic performance, at the planning and design stages for similar sporting facilities in the future.

School gymnasium is a multi-purpose large space building for various events and physical education activities, and is a facility that requires an approach to the desirable structural design, besides mechanical problems of structure against loads. For the integrated structure design concerning the architectural features, the major considerations of gymnasium planning that are the internal and external shape of the gymnasium, the space scale with structure members, the structural efficiency by members weight reduction and openness of the gymnasium space will have to take into account in the structural planning. From this point of view, the several cases of the school gymnasium were investigated and the parametric analyses were performed to the models using the various structural system. The parameters were the composition elements of structure system that are profile of structure, rigidity of member, connection and anchorage and stability. At the result, It was presented that the profile of structure member was the most influential factor to structural efficiency and the effect of the form and space of gymnasium. Also the design informations of structure design having the various feature of form and space were presented for the initial gymnasium planning.

In case of the large-scaled indoor gymnasium that has been constructed in the local area, there are many instances for the use as multipurpose space where the public performances are possible such as leisure activity, lecture, assembling activity, drama, concert and so on for the resident together with the purpose of sporting facility. In order for utilization to the maximum of the function of such indoor gymnasium, the acoustic capabilities concerned with Definition of both Voice and Music are simultaneously required. However, in case of the large-scaled athletic facility, since it was designed with high ceiling-height in view of its characteristics, it forms a Sound Focus and then the sound is concentrating to the specific part, and because the vibration of sound is too loud due to its broad volume, the acoustic defects such as many Echoes are arising. On such viewpoint, based on the drawing of the indoor gymnasium that is scheduled to be built at B County, Chonbuk Province, this Study has proposed such indoor gymnasium equipped with the optimized acoustic condition passing through Acoustic Simulation Phase. As the result of Acoustic Simulation, we could design the indoor gymnasium that equipped with really satisfying acoustic performance 'after' reformation compared with 'before' reformation, and it is considering that such material could be utilized as the fundamental material that brings a curtailment effect of the construction cost and also enables us to improve the acoustic performance, at the stage of planning and designing for the similar sporting facility in the future.

Now days, as the consideration of sound environment is getting important, method of physical measurement such as reverberation time and sound pressure level becomes common. However, such method cant include subjective sensation such as personal emotion and feeling, evaluation. So there is a limitation to make the most optimized sound environment. Therefore, in the present experiment, I improve big indoor gymnasium that has sound defect because of too long reverberation time. After that, I conduct the auditory sense evaluation of human psychological response. From the experiment, I will make research into sound satisfaction rate about the subject space and response of each item. As well as, I will present the result as basic database of sound environment improvement experiment of indoor gymnasium.

The purpose of this study is to provide fundamental heating design data for the large public enclosures as gymnasium. This study executed indoor thermal environment verification of the existing gymnasium by measuring temperature distribution with and without heating the space in winter. Heating loads from human body was not considered. We examined various indoor thermal environment factors of the large enclosed space in this study which include vertical and horizontal temperature distribution, supply and return air flow feature, thermal comfort environment feature, amount of ventilation and etc.

The purpose of this study is to provide fundamental cooling design data for the large public enclosures as gymnasium. This study executed indoor thermal environment verification of the existing gymnasium by measuring temperature distribution with and without cooling the space in summer. Colling loads from human body was not considered. We examined various indoor thermal environment factors of the large enclosed space in this study which include vertical and horizontal temperature distribution, supply and return air flow feature, thermal comfort environment feature, amount of ventilation and etc.

This study aims to investigate and evaluate the room acoustic designs of a multi purpose gymnasiums which do not use adjustable treatments in order to change the acoustical characteristics. Considering the main uses of gymnasium and auditorium, experiments were carried out using both nondirectional speakers on the stage and loudspeaker installed on the ceiling. The result from the study are as follows; Measured RT under unoccupied condition was a little longer than the expected value, therefore, in the case of occupied condition RT would be close to the optimum value. However, parameters that evaluate intelligibility and speech transmission property appeared to be low and have large differences depending on the measuring points, therefore, more effective sound reflecting surfaces and sound reinforcement systems should be considered.
