  • 본 연구에서는 평면스피이커의 진동판의 진동을 이론적으로 해석하고 시간 평균 홀러그래픽 간섭계로 조사하여, 지지대의 지지위치 선정과 피스톤 진동 모우드를 넓히는 방법을 제시하고, 비틀림이 적은 진동판을 설계하는 방법을 제시하여 평면스피 이커의 성능을 항상시키는 데 있다.

  • The objective data and subjective data correlated in order to rate sound quality of loudspeaker system and these data were analyzed by the Factor Analysis and Multi-Dimensioinal Scaling. The dimensions yielded Factor Analysis were interpreted as "Contrast", "Metallic", "Rich", "Present" and their relation to physical variables were explored by studying the positions of loudspeaker systems in the respective dimension. When the subjective similarity degree of loudspeaker systems was compared with the objective similarity degree of loudspeaker systems by Multi-Dimensional Scaling, the similarity degree of sound pressure response in the listening room closely coincided with the subjective similarity degree regardless of sound source. This result implies the necessity of measurements taken not only in an anechoic room but also in a listening room in order to rate sound quality of loudspeaker systems.
