And then Rountree would hold it underwater, near a hydrophone, to capture the sounds it made.

之后，朗特里将鱼放在水中接近水听器的位置，录制鱼发出的声音。

We're going to have these two hydrophones connected to it.

我们要把这两台水下听声器和它接在一起。

We can eavesdrop on these songs using underwater microphones called hydrophones.

我们可以使用称为水听器的水下麦克风来窃听这些歌曲。

We could plant hydrophones on the side of the lagoon.

我们可以在泻湖的一侧沉入水下听音器。

So the hydrophone was sort of a trial run.

那么放水下听音器是次试验。

But the group reported recently that it was working with the hydrophone operators to collect data that will be closely examined.

但该组织最近报告称，他们正在与水听器操作员合作，收集数据来仔细检查。

Gabriele and other researchers are tuning into a network of hydrophones, which are basically underwater microphones, to document these changes.

Gabriele 和其他研究人员正在调整水听器网络（基本上是水下麦克风）来记录这些变化。

They would drop a hydrophone off the side of a kayak while they paddled through fields of seagrass or cruised near freshwater river mouths.

当乘船划过海草田火灾淡水河河口附近巡游时，她们会顺着皮艇边放下水听器。

And thanks to hydrophones that record whales onto the water scientists have discovered there are at least eight different species of whales swimming near the Big Apple.

由于潜水测音器可以记录鲸鱼在水面上的活动，科学家们发现至少有八种不同种类的鲸鱼在纽约附近游泳。

The eerie low frequency sound was picked up by hydrophones, and sounded similar to an oxygen bubble rising up from the water towards the surface.

这种怪异的低频声音被水听器接收到，听起来就像一个氧气泡从水面上升到水面。

Underwater tests produce distinctive sounds that travel efficiently around a kilometer below the surface of the ocean and these can be picked up by hydrophones.

水下测试产生独特的声音，这些声音可以在海面以下一公里处有效传播，并且可以被水听器拾取。

And, in future studies, the researchers plan to listen directly for acoustic waves, using a network of hydrophones first intended to monitor for nuclear explosions.

而且，在未来的研究中，研究人员计划使用最初用于监测核爆炸的水听器网络直接收听声波。
