The history of architectural acoustics is a part of history of human being getting together for both politics and entertainments, is also a part of the history of nobility pursuing hearing enjoyments, is still a part history of scientists deeply understanding the concept of "just for people", and as well as is a part history ceaselessly driven by the musicians to find their real hearts through music. The history of architectural acoustics explains not only the acoustic knowledge developments in architectural design, but also the unity on contradictory of both the science and the arts, both the technology and the culture, both the sense and sense organ. The history of architectural acoustics prints the interactions between the mankind and the nature, between the mankind and themselves, between the mankind and their souls, in which course people understand their feelings more deeply and deeply. This paper discusses the brief history of architectural acoustic in China from the ancient drama stages to grand theaters in 20 century, even up to nowadays, including some most important buildings and events as well.

By virtue of recent economic development and cultural progress, the desires willing to enjoy a plentiful leisure life among people are on enlarging, then according to this, the demand for a grand performance hall where various cultural events are achievable is also on increasing. However, since the grand performance hall has its characteristics that must accommodate various forms of performances likely from lecture, meeting activity to recital, and because the clearness of sound is on emphasizing, and also it requires the repletion or abundance of sound simultaneously, it could be said that from the designing stage, a sufficient examination and plan with regard to the architectural acoustics design is indispensable. On such view point, for the object of the grand performance hall under actually planning to build, this Study is attempting to compare analyze on Room Acoustics Characteristics using computer simulation from the stage of design. It is considered that the material analyzed in such way could be reflected in maximum basis to the design of the performance hall that minimizes the acoustic defect at the designing step, and also it could be utilized as the useful material at the time of design for a similar form of performance hall in the future.

In airport terminal, aural information is transmitted during 24 hours a day including announcement, background music and emergency control. So, clear sound is mostly necessary to transmitted to the passengers in airports. IIA (Incheon International Airport) is one of the largest airports accommodating 45 million people a year which have been built since 2001. There are currently three passenger terminals including Terminal 1 & 2, and boarding concourse. The $2^{nd}$ passenger terminal is under construction to expand the spaces which will be finished in 2020. The present work aims to explain the design principles of both architectural acoustics and electo-acoustics which have been applied to all the terminal buildings in IIA including ticketing counter, great hall, departure concourse and transportation center. Also, the acoustical performances of those spaces were examined. As a result, acoustic standards for airport were suggested. Architectural concepts for designing ceiling spaces and sound absorption treatments were suggested. Also, electro-acoustic design principles were commented.

In case of domestic performance hall, it is real situation that the demand of multipurpose hall that accommodative a lecture, gathering activity, drama and concert than a professional performance hall such as opera house, is on increasing. Accordingly, since such multipurpose hall, in view of its characteristics, is emphasizing the clearness of sound, also it requiring the repletion or abundance of sound simultaneously, it could be said that the sufficient examination and plan with regard to the architectural acoustics design is indispensable. However, since most of multipurpose hall has ever been designed and constructed without any consideration on an acoustic factor, many problem points are generating. Standing on such viewpoint, this Research has measured the physical acoustic characteristics about the small-scaled multipurpose hall recently built without any acoustic consideration, and through the above, tried to grasp the acoustic defect and controversial point thereof. It is deemed that such study result could be utilized as an important material for improvement the acoustic performance of the multipurpose hall.

Domestically, demands for multi-purpose performance venues which accommodate various performance genres have increased. However, those venues have limited capability and confined to a primary performance. The present work investigated various methods for controlling the acoustics of room for required performance genres by reviewing aurally presented and published materials. The method of varying the acoustics of a space is called Variable Acoustics, and adjusted in either passive and active ways. Passive control encompasses variable absorption, variable volume, coupled volume, and canopy reflectors, where the acoustics of a room is controlled in an architectural way. Active control includes In-line, Regenerative, and Hybrid systems where the acoustics of a room is manipulated electronically. The mechanism and application of each passive control system in existing venues are reviewed and their pros and cons are discussed. Also, the concept of each active systems and product applications are looked at through literature reviews. Lastly, some considerations that need to be taken into in the planning and design stage of a multi-purpose hall using Variable Acoustics are suggested.

This paper describes the acoustical conditions of elementary school and high school classrooms as well as university classrooms in Korea and suggests a need for Korean acoustic standards and guidelines for classroom design. Current standards and guidelines of classroom acoustics in several countries were briefly introduced to understand their acoustical performance criteria for background noise levels and reverberation times, and noise isolation design requirements in various types of classrooms. The results of several acoustic survey of domestic classrooms in elementary school, high school, and university were described and compared to provide information of the acoustic characteristics of Korean school classrooms. The survey includes occupied and unoccupied data on the acoustical conditions, noise levels, and noise isolation performance in the classrooms. Acoustical parameter values for achieving 'good' speech intelligibility in active university classrooms were also presented.

Recently, many membrane structure buildings are constructed with the trend of multi functional and high technological construction. The membrane structure has the characteristics such as distinguished architectural shape which can make variable space creation and can make economic use of material. Therefore, it is in the spotlight of sport complex, various concert hall, and public service buildings. However, the acoustic study of membrane structure has not been following up the increasing demand for the membrane structure. In this study, the acoustic characteristics of membrane structure will be studied and analyzed using architectural acoustic factors based on acoustic design theory And also, the differences between theoretical exhortation value and outcome of study will be studied with the basis of architectural acoustic material study.

The purpose of this study is to grasp musical expression in the Monastery of La Tourette, an architectural work produced by an architect, Le Corbusier and a musician, Iannis Xenakis based on a musical piece, Metastasis. The results of the study on musical expression in the Monastery of La Tourette, which was done through analysis of correlation in expression between architecture and music, and spatial characteristics of this monastery, are as follows: First, in modern architecture and music, the expression of the space-time continuum concept is emphasized. Second, the architectural characteristics in this monastery that constitute musical expression are the Modular, confliction and fluidity in composition, plastic (acoustic) shape and symbolic shape. Third, these architectural characteristics are found to be expressed as counterpoint, alteration, temporality, acoustics and canon of music.
