It can be drawn from the simulation of the sea adaptive filter adopting various algorithms mentioned that the LMS, NLMS, QRRLS and QRDLSL are all effective to denoise the sea noise.

仿真结果表明最小均方自适应算法、归一化最小均方算法、基于QR分解的平方根信息自适应滤波器和基于QR分解的最小二乘格型自适应滤波算法都能有效地滤除海浪噪声。

The council said it had had nine letters of objection, including complaints from the South Hill Residents Association that the new pier would obscure the sea view, the extra height would mean it overlooks houses and it had the potential to create extra noise.
