And we see this lower frequency formant here.

我们可以看到这个共振峰。

These high-frequency wavelengths, more than 10 times higher than what we can hear, are small enough to generate strong reflections from objects as tiny as the insects many bats are after, which would be missed altogether by lower ones.

这些高波长（比人类能听到的波长高出 10 多倍）短到可以从许多蝙蝠捕食的昆虫等微小物体上产生强烈反射，而波长的反射则会完全错过。

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

You know, not all the sounds in the airplane, but that general rumble, those low frequency sounds you're trying to get rid of, they're pretty predictable.

你知道，不是飞机上所有的声音，但是一般的隆隆声，那些你试图消除的声音，它们是可以预测的。

They can do this thanks to the SOFAR channel, or Deep Sea Channel, that generally starts at 1, 970 ft, but can vary in depth.

长须鲸能发出这样的声音，要归功于深海声学通道，即深海通道，一般从 1970 英尺处开始，但根据深度变化可能会有所不同。

After taking a photograph, this technique creates two of these albedo maps: one is a complete, low frequency map, which records the entirety of the face, but only contains the rough details.

拍摄照片后，这种技术会创造出这样两张无光颜色贴图：一张是完整的地图，能记录整个脸部，但只能包括一些粗略的细节。

The researchers will further focus on nanohertz gravitational waves and open up a new scientific direction of nanohertz gravitational wave astronomy, and continue to maintain the country's leading position in low-frequency radio astronomy in the world, said Chang.

研究人员将进一步聚焦纳赫兹引力波， 开辟纳赫兹引力波天文学新的科学方向，继续保持我国在射电天文学领域的国际领先地位。

You can produce a noise so low and so deep not only it goes through the air, it goes through the rocks and through the soil, and you pick it up in your feet.

极的声音不仅能在空气中传播，而且能在岩石和土壤中传播，用脚就能感知到。

The low frequency of a cat's purr causes their insides to vibrate in a way that helps heal bones and cuts, build muscle, dull pain, and even make breathing easier.

猫的呼噜声会导致它们的身体内部以一种有助于愈合骨骼和伤口、增强肌肉力量、减轻疼痛，甚至让呼吸更容易的方式振动。

Growling is quite a distinct sound, and other animals that are much larger use low-pitched sounds, when they're being threatening.

嚎叫是非常特殊的声音，其他大型动物在感受到威胁时，会使用的声音。

She oversaw the development of the country's universal time system and its use of low-frequency radio waves as a form of measurement, which laid the groundwork for the space programme.

她挑起了建立中国世界时系统的重担，及其作为测量形式的无线电波的使用，这为空间方案奠定了基础。

These low frequencies can trigger distinct psychological effects, including things like discomfort, a sense of panic, and an overall sense of something being out of place.

会触发明显的心理效应，包括像不适，恐慌感，还有总之哪里不对劲的感受。
