And we see this lower frequency formant here.

们可以看到这个低频共振峰。

And the areas with the longer fibers resonate with lower-frequency waves.

纤维较长的区域与低频波共振。

We do retain most of all low frequency sounds.

们确实能听到大部分低频声音。

Noise-canceling headphones are best, removing persistent low-frequency hums.

降噪耳机最擅长去除持续的低频嗡嗡声。

So they broke out a set of very very low frequency speakers.

他们搞了一套非常非常低频的扬声器。

So the way we're going to do this is we're going to listen to the low end first.

们的做法是先听一下低频。

They're particularly well-tuned to low frequencies, including those emitted by dying fish.

听觉达到了水下800米以远，尤其能够识别低频声波。

Although we can't hear these low sounds, we can feel them.

虽然们听不见这些低频的声音，但们能感觉到。

At the lower end of the spectrum, there's radio, infrared, and visible light.

在光谱的低频端的是无线电，红外线，和可见光。

Low-frequency noise, in particular, just goes through the trees as though they aren't there.

特别是低频噪音无视树木的存在，直接穿过他们释。

These cats can pick up very low-frequencies, a helpful skill in the open desert where low sounds travel the furthest.

这些猫能够捕捉到非常低频的声音，在开阔的沙漠中，低频声音传播得最远。

Now they knew lower frequency words but they hadn't mastered those most important words.

他们知道低频词，但是他们还没有掌握那些最重要的单词。

These sizable sound-collectors help the jerboas sense low frequency noises, and keep cool by radiating heat.

这些体型巨大的声音收集器帮助长耳跳鼠感知低频噪音，并通过散热保持凉爽。

At the other end, in the deep infrasound, elephants and whales, tigers and some birds make sound.

另一端的低频次声，大象、鲸鱼、老虎和一些鸟类会制造这样的声音。

Over a combined total of 26 hours, 32 calls were captured—including some low-pitched pulses.

总计超过26小时的记录时间内，一共收到32个声音文件—包括了一些低频声波脉冲信号。

We register short waves at high frequencies as bluish colors, while long, low frequencies look reddish to us.

们将高频的短波记录为蓝色，而长的低频在们看是红色的。

This could be triggered by low or high-frequency vibrations, a stretch, or simply light, static pressure.

这可能会由低频或高频的感受、拉伸，或仅仅由轻微的静态压力所引发。

Even more effective, low-frequency sounds, with their long wavelengths, travel much further than high frequencies.

更有效的是，低频声音波长较长，比高频声音传播得更远。

Developed by professor David Premack, the Premack principle states, " More probable behaviors will reinforce less probable behaviors."

由大卫·雷马克教授提的雷马克原理指：“高频行为会强化低频行为。”
