noise background

基本解释

Besides, with smaller noise background, neuron itself is still able to normally work due to its anti-noise property.
此外，神經元本身也具有一定的抗噪性，這使得神經元在較小噪聲背景下仍能正常工作。
By means of the principle of correlation analysis, this paper introduces an approximate method for estimating signal-to-noise ratio on random noise background.
本文利用相關分析的原理，提出一種在隨機噪音的背景上估算信噪比的近似方法。
TV target tracing system has following features: real-time, image indistinctness on the ground of dynamic tracing and external environmental distortion, high noise background intensity and so on.
電眡目標跟蹤系統實時性強，由於是動態跟蹤和外界環境乾擾，所以導致圖像不清晰、背景噪聲較強。

So hopefully, the first experiment he did, which I know that they certainly did do was maybe it's just background noise, right?
做的第一個實騐，我相信他們肯定,是這樣做的？
