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，神经元本身也具有一定的抗噪性，这使得神经元在较小噪声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.
本文利用相关分析的原理，提出一种在随机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.
电视目标跟踪系统实时性强，由于是动态跟踪和外界环境干扰，所以导致图像不清晰、背景噪声较强。

So hopefully, the first experiment he did, which I know that they certainly did do was maybe it's just background noise, right?
做的第一个实验，我相信他们肯定,是这样做的？

And the fact that we're always facing some risk of death recedes into the background in the way that most of us don't hear background noise-- that what jumping out of an airplane does for you is it spikes the risk of death.
我们一直面对的某些死亡的风险,这种情况下变成了背景声音,因为我们大部分人都听不到背景的噪声-,而跳下飞机带给你的,是死亡的风险上升。
