This filter can effectively restrain background noise and acquire clear speech signal when applied in speech signal pick-up from the background with complex noise.

将此滤波器应用于复杂噪音背景的话音信号提取，能很好地抑制背景噪声，从而获得清晰的话音信号。

A particular feature of the technique is that the influence of background noise on reconstructed results can be removed while retaining the background noise in the holographic measurements.

该技术的一个突出优点是在具有背景噪声的全息测量情况下，可以消除背景噪声对全息变换结果的影响。

The background noise of the reconstructed image is resulted from the nonnegative coded function. A method of constructing composite hologram for reducing the background noise is proposed.

对于编码函数非负给物体的再现像带来的背景噪音。提出采用构造复合全息图的方法来消除。

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。

It also features noise cancellation that filters out background noise so consumers can hold crystal clear conversations in any environment.

This new research, then, will serve multiple functions: Using specialized sensors, processors, and algorithms, the project team will measure noise in real time, tracking both the noise generated by various pieces of wave energy equipment and general background noise.
