This slight delay helps their brains determine the direction of the sound's source.

这种轻微的延迟有助于它们的大脑判断声源的方向。

So it increased the distance from the sound source, ok, which was identified as a potential danger.

猫头鹰增加了与声源的距离，这被认为是一个潜在的危险。

And all of these sound sources are decreasing the acoustic space over which Arctic marine mammals can communicate.

这些声源全都减少了北极海洋哺乳动物 可用来沟通的音域频宽。

They almost invariably approached the sound source and in many cases did so in sort of an aggressive manner.

“它们几乎总会走近声源，许多时候还会展现出咄咄逼人的架势。”

Researchers originally proposed using artificial sound sources, but that notion got nixed because of concerns about the impacts on marine animals.

研究人员最初提出使用人造声源，但由于担心对海洋动物的影响，这个想法被否决了。

Or I should put it as the sound source that we want to hear versus the sounds that we don't want to hear.

或者我应该将其视为我们想听到的声源与我们不想听到的声音。

The new study instead uses a natural sound source for investigation: earthquakes rumbling beneath the seafloor off the coast of Sumatra that drum up acoustic waves in the ocean.

这项新研究反而使用自然声源进行调查：苏门答腊海岸海底下方的地震隆隆作响，在海洋中产生声波。

Localization means that we can pick a pixel in the image and it show us the sound that comes from that location, and the separation part means that ideally, we only hear that particular sound source.

定位意味着我们可以在图像中选取一个像素，它就会播放来自那个位置的声音，分离意味着理想情况下我们仅能听到那个特定的声源。
