This paper investigates stage acoustics in concert halls for ensemble performance in terms of stage support parameters. A concert hall with large stage area was selected. Objective measurements were carried out according to Gade's methods for investigating stage support (ST1). The sound field on the stage was evaluated using stage and audience acoustical parameters. According to the positions at stage, different acoustical characteristics were found. Higher ST1 and lower $IACC_{E3}$ were measured near side and rear stage walls. In case of conductor/soloist vs. orchestra player, objective measurement of acoustical parameters shows that early sound fields depend on the source-receiver distance but late sound fields depend on the location of side and rear walls. In addition, in-situ evaluation of the trio instrumentalists was carried out. Results show that ensemble is favored by higher early reflection of sounds and sound diffusion affecting ‘blending’ of their performance.

Berlin Philharmonic Concert Hall is one of most prominent architecture of Hans Scharoun, which is known as the fine combination of the functionalism as an important factor in modern architecture and the hi-developed technology Moreover, the plan and spatial planning of the concert hall is famous for its evolutionary approach compared to other traditional concert halls. The objective of this paper is to examine forms and organic system of functions of this concert hall in order to re-evaluate it's historical meanings in our modern architecture history, The current study will also look into how the personal background of Hans Scharoun has influenced his design in various ways, especially the inside of lobby and auditorium of Berlin Philharmonic Concert Hall.

이번에 소개할 건물은 대만의 항구도시로써 국제적 요충지 구실을 하면서 문화적으로 점차 융성해 가고 있는 가오슝에 위치하고 있는 국립 예술 가오슝 센터(The National Kaohsiung Center for the Arts(Wei-Wu-Ying)) 이다. 2000 좌석의 콘서트홀과 2250 석의 오페라홀, 이외에도 크고 작은 극장을 겸비하고 있는 이 시설은 네덜란드의 건축사 그룹 Mecanoo에 의해서 설계되었다. 이곳은 전 군사기지였던 곳을 아열대 공원으로 형성시킨 숲을 바라보는 곳에 위치한다.

K 문화센터는 공연 및 전시를 위한 고품격 문화 시설로서 주요 시설인 공연장은 규모 및 용도에 따라 오페라 극장, 콘서트홀, 실험극장으로 구분되어 있다. 공연장은 타 공간에 비해 높은 정숙도와 쾌적한 내부 환경, 피난 계획 등을 필요로 하기 때문에, 이를 만족하기 위해서는 실의 특성에 적합한 공조 설비, 방음.방진 및 방재 설비 등이 뒷받침되어야 한다. 따라서 본 설계사례에서는 최고 수준의 공연장 계획에 적합하도록 각 분야별로 적용된 시율레 이션 기법 및 신공법과 함께 주요 기계설비 계획에 대해 소개하고자 한다.

The effect of diffusers on Early Stage Support (ST1) in a concert hall was investigated at 8 positions in a 1:25 stage scale model. Experiments were carried out when the stage floor was covered with and without absorption cloth to investigate the effect of stage floor reflection (absorption coefficient - 0.6 at 500Hz). To find out the effect of stage wall. three types of wall diffusers were used. As a result. absorption cloth on stage floor reduced the ST1 values at high frequency. but the average value of ST1 was not changed. Three types of stage wall diffusers were revealed as unaffecting. but it was observed that the ST1 values varied to positions of stage. The ST1 values were evenly distributed when hemisphere diffusers were used. Therefore. the use of floor absorption did not have much effect on the ST1 values, and the diffusers had some effect on the distribution of the ST1 values.

This study investigated that the preference model of soloist performers for both vocal and instrumental types in terms of a stage support parameter, ST1. The test was carried out on a stage of a fan-shaped multi-purpose hall with orchestra shell. Objective measurements were carried out at 15 positions on the stage to evaluate various stage condition. The results showed that ST1 varies between -19.9 and -11.3 dB. Vocal and instrumental players participated in performance evaluation test as they played at 5 selected positions according to ST1 values. Players' preference was evaluated by 5-point rating and rank ordering method. As a result, it was found that the preference model of vocalist is different from that of instrumentalist. It was also found that the ST1 does not correlate well with the performer's preference.

서양음악의 연구는 음향학의 측면에서 수십년 동안 연구가 진행되어왔다. 이를 통해 콘서트홀의 음향학적 특성을 평가할 수 있는 객관적 지표들을 제시할 수 있었다. 하지만 국악에 있어서는 공연장에 대한 음향학적인 지표가 공식화된 것이 없고, 게다가 지표를 찾기 위한 충분한 국악전용 공연장의 수가 부족하다. 따라서 본 논문에서는 국립국악원 예악당의 모델을 기초로 한 컴퓨터 모의실험을 통해서 얻어진 가상 국악공연장을 바탕으로 RT, Warmth, IACC, ITDG 등의 4가지 지표를 가지고 각기 다양한 시료를 제작하여 청취실험을 실시하였다. 그 결과 서양음악과는 다른 경향의 RT, Warmth 선호도를 추출할 수 있었다.

The accuracy of sound strength (G) measurement method in ISO 3382 has been questioned. One of the main reason is the difficulty in measuring a reference sound level in an anechoic chamber with the same set-up which was applied for the actual hall measurements. In the present paper, an in-situ measurement method for G was proposed by investigating the present G measurement method shown in ISO 3382. In addition, the sound radiation characteristics of typical omnidirectional loudspeakers were investigated and Phi (O) of auto correlation function (ACF) parameters was also calculated from an actual music excerpt to characterize the sound energy distribution in concert halls.
