Abstract

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.

국내에서는 다양한 공연장르를 운영할 수 있는 다목적 공연장의 수요와 그에 따른 공급이 지속적으로 증가해오고 있다. 그러나 음향적인 측면에서는 다목적 활용에 대응하는 실질적인 고려가 이루어지지 않고 있으며, 많은 시행착오를 거듭하고 있다. 본 논문에서는 다양한 장르의 공연이 한 공간에서 이루어질 수 있도록 실의 음향특성을 변경하는 방법들을 문헌고찰을 통해 살펴보았다. 실의 음향특성을 용도에 맞게 변화시키는 것을 가변음향이라고 하며, 수동 및 능동제어방식으로 구분된다. 수동제어방식은 가변흡음, 용적가변, 부가잔향실법, 그리고 캐노피 반사 등의 방식으로 구분되는 건축적인 가변방식이며, 능동제어방식은 In-line, Regenerative 그리고 Hybrid 시스템으로 전기적인 방법에 의해 제어된다. 본 연구에서는 각각의 수동제어방식들이 실제 다목적 공연장 및 다양한 장르에 적용된 사례와 그 장단점을 살펴보았다. 또한 각각의 능동제어방식이 적용된 시스템들을 살펴보고, 실제 다목적 공연장에 적용된 사례와 그에 따른 음향적 변화에 대해 알아보았다. 마지막으로 가변음향시스템을 활용한 다목적 홀의 기획 및 설계 단계에서 고려사항을 제안하였다.
