Abstract

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.

공항의 여객터미널은 안내방송과 배경음악, 긴급안내등이 24시간 이루어지는 곳이기 때문에 명료한 음성의 전달이 매우 중요하다. 인천국제공항은 연 4천500만명 이상의 여객을 처리하는 가장 큰 공항으로서 2001년부터 운영되고 있다. 인천국제공항에는 제1여객터미널, 탑승동, 제2여객터미널 등 3개의 터미널이 있으며, 현재 제 2여객터미널의 확장공사가 2020년까지 진행되고 있다. 본 논문은 인천국제공항내의 모든 여객터미널의 설계시 적용된 건축음향과 전기음향설계의 기본원칙을 설명하였다. 특히, 대규모 체적을 보유한 출발홀과 중앙홀, 교통센터등의 음향성능을 분석하였다. 연구결과로서, 공항의 대형공간에 대한 음향설계 기준을 제시하였으며, 터미널 천정의 설계와 천정의 흡음에 대한 방안을 제시하고, 더불어서, 전기음향설계의 원칙에 대한 방안을 제안하였다.
