실제 제어 영역의 폭과 제어점의 제어 주파수 사이의 관계를 활용한 견고한 다채널 사운드 재생 시스템을 제안합니다. 고정된 역필터 계수를 사용하면 실내 환경 변화로 인해 기존 사운드 재생 시스템의 재생 정확도가 감소합니다. 이러한 경향은 제어점을 더 가깝게 배열할수록 더욱 두드러집니다. 이 문제를 해결하기 위해 모든 제어점의 주파수 제어 대역을 전환하여 저주파에서 재생되는 사운드의 저하를 방지하므로 양쪽 귀의 제어점의 통과 대역 범위는 고음역만 됩니다. 다른 제어점은 전체 제어 범위입니다. 실제 환경 데이터를 이용한 수치 시뮬레이션에서는 6.1도의 온도 변화에도 불구하고 재생 정확도가 평균 약 5dB 향상되는 것으로 나타났습니다.

Abstract: A robust multichannel sound reproduction system that utilizes the relationship between the width of the actual control area and the control frequency of the control points is proposed. The reproduction accuracy of a conventional sound reproduction system is reduced by room environment variations when fixed inverse filter coefficients are used. This tendency becomes more significant when control points are arranged more closely. To resolve this problem, the frequency control band at every control point is switched to avoid degrading the reproduced sound in low frequencies, so the pass band range of the control points at both ears is only high-range. That of the other control points is the entire control range. Numerical simulation with real environmental data showed that improvement of the reproduction accuracy is about 6.1 dB on average, even with a temperature fluctuation of 5
