Abstract

This study is a preliminary study about applying Active Noise Control (ANC) to reduce underwater radiated noise from ship propellers. In this research, simulations of active noise control using a virtual controller were performed to predict the noise reduction effects and changes in the sound field due to ANC on underwater propeller noise. The simulation results showed that while the Blade Passing Frequency (BPF) component of underwater propeller noise has a low frequency, the noise generated by the propeller has an impact waveform, necessitating a controller with a high sampling rate of over 40 kHz in the Filtered-X Lesat Mean Square (FxLMS) algorithm. Additionally, it was observed that in the case of Single-Input Single-Output (SISO) active noise control, noise reduction is achieved in the direction of the error microphone, but noise increases in the direction opposite to the error microphone. The findings of this study provide guidelines on the conditions and performance of noise reduction for active noise control of underwater propeller noise. Based on these results, the preliminary conditions and validation steps for active noise control of propeller noise in naval vessels are proposed.

본 연구는 함정 프로펠러에서 발생하는 수중 방사 소음을 저감하기 위해 능동 소음 제어 적용을 위한 예비 연구로 진행되었다. 본 연구에서는 가상 제어기를 이용한 능동 소음 제어 시뮬레이션을 이용해 능동소음제어(Active Noise Control, ANC) 에 따른 수중 프로펠러 소음의 저감 효과 및 음장 변화를 예측하였다. 시뮬레이션 결과, 수중 프로펠러는 낮은 주파수의 날개통과 주파수(Blade Passing Frequency, BPF) 성분을 가졌으나 충격 파형 특성을 갖는 것으로 나타났다. 이에 FxLMS 알고리즘 ANC를 이용해 수중 프로펠러 소음을 저감하기 위해서는 40 kHz 이상의 높은 샘플링 레이트를 갖는 제어기가 필요하였다. 또한, 단일 입력 단일 출력(Single-Input Single-Output, SISO) ANC의 경우 에러 마이크 방향으로 소음 저감이 가능하였지만 에러 마이크와 반대 방향에서는 소음이 증가하는 현상이 나타났다. 본 연구에서는 시뮬레이션을 통해 수중 프로펠러 소음에 대한 ANC 적용을 위한 조건 및 ANC 적용에 따른 저감 성능을 확인하였으며, 이를 통해 함정 프로펠러 소음에 대한 능동소음제어를 위한 선행조건 및 검증 단계에 대해 제시하였다.
