Wind noise has detrimental impacts on audio equipment. This paper evaluates the impact of wind noise on the noise control performance of ANC headphones in a variety of windy environments. The findings indicate that the noise reduction performance of headphones degrades as the wind speed increases. To improve the performance of ANC systems in windy environments, the diffusion filtered-x least mean squares (Diff-FxLMS) algorithm has been employed that can effectively suppress the wind noise and disperse the computational burden among nodes across acoustic sensor networks. The theoretical analysis of the Diff-FxLMS algorithm in wind noise environment indicates that an estimation bias has been introduced in the steady-state solution. Computer simulations using recorded wind noise and measured acoustic channels demonstrate that the diffusion algorithm could improve the noise reduction performance in windy environments up to 5 dB approximately.

风噪声对主动噪声控制耳机的影响以及分布式滤波 x 最小均方算法中的风噪声抑制

风噪声对音频设备有不利影响。本文评估了各种有风环境下风噪声对 ANC 耳机噪声控制性能的影响。研究结果表明，耳机的降噪性能随着风速的增加而降低。为了提高ANC系统在大风环境中的性能，采用了扩散滤波x最小均方（Diff-FxLMS）算法，该算法可以有效抑制风噪声并分散声学传感器网络节点之间的计算负担。对风噪声环境下Diff-FxLMS算法的理论分析表明，稳态解中引入了估计偏差。使用记录的风噪声和测量的声学通道进行计算机模拟表明，扩散算法可以将大风环境中的降噪性能提高约 5 dB。
