Noise can be eliminated via the orthogonal decomposition of seismic data followed by eigen extraction. 通过对地震记录进行正交分解和特征提取，可消除噪声。
To eliminate the residuals caused by noise, a new phase filtering method is proposed to reduce the noise in the phase data. 同时，针对磁共振相位解缠绕中的噪声问题，本文提出一个新的滤波方法，可以高效地消除噪声导致的解缠绕的不一致性。
Designing air cleaner with good performance of noise reduction is one of the effective ways for the intake noise control. 设计消声效果良好的空气滤清器是控制发动机进气噪声的有效措施之一。
Suitable noise and vibration isolation, and protection against freezing must be provided. 必须提供适当的消声和隔振以及防冻措施。
