在游艇舱室中，高质量的吸波材料可以很好地降低中高频噪声，但对于低频噪声则完全无效。本文对游艇环境中的低频噪声进行了详细的分析；根据不同噪声源（如空调、发动机）和不同航行速度的存在，研究了几种船况。在这种情况下，一个特定的多通道反馈主动噪声控制系统，源自众所周知的滤波-x方法，设计并安装在游艇的卧室中，为了减少声学烦恼，使用四个错误麦克风和两个低音炮来产生降噪。最后给出了实际实验结果，验证了该系统的有效性。
In a yacht cabin, high-quality absorbing materials can reduce in a good way medium and high-frequency noises, but they are completely inefficient in the case of low-frequency noises. In this brief, a detailed analysis of low-frequency noises in a yacht environment is presented; several boat conditions, depending on the presence of different noise sources (e.g., air conditioning, engines) and various navigation velocities are investigated. In this context, a specific multichannel feedback active noise control system, derived from the well-known filtered-x approach, is designed and installed in a bedroom of a yacht in order to reduce the acoustical annoyance using four error microphones and two sub-woofers for antinoise generation. The results of practical experiments are shown in order to demonstrate the effectiveness of the proposed system.
