- The distance between the acoustic-emission source and the receiving transducer, and the background noise level are primary factors in selecting a particular frequency band. 声发射源与接收讯号传感器间的距离以及环境噪声的电平是选择频带的主要依据。
- Conventional methods cannot work well in the condition of low SNR or at a variable background noise level. 常规的检测算法在低信噪比尤其在背景噪声能量可变的环境下不能有效工作。
- The gravity observation residuals and station background noise level are also investigated. 文章还研究了重力观测残差和台站背景噪声水平。
- Thus as the signal level drops, the higher frequencies are progressively more strongly filtered, which also filters the constant background noise level. 也就是说随着信号等级降低，高频声音越来越多被过滤，静态的背景噪音也被过滤。
