Can Noise Have Color?

You may have heard the phrase "white noise," but what does it mean?

When there's a lot of different sound signals at once we often consider it "noise."

Noise has an inherent randomness.

It's a mix of unpredictable signals.

But there are different varieties of noise, patterns within that randomness.

When a cat makes that "ssssss" sound, zillions of air molecules create sound across a broad range of frequencies.

We call it "white noise" because it has basically equal power for all frequencies of audible sound, just like white light has equal power for all frequencies of visible light.

And just as we call different frequencies of light different colors, we call different mixes of sound frequencies different colors of noise.

sentence:
你可能听过“白噪音”这个词,但它是什么意思呢?
当同时有很多不同的声音信号时,我们通常认为这是“噪音”。
噪音具有固有的随机性。
这是一种不可预测信号的混合。
但在这种随机性中有不同种类的噪音和模式。
当猫发出“嘶嘶”的声音时,无数的空气分子会在很宽的频率范围内发出声音。
我们称它为“白噪声”,因为它对所有频率的可听声音都具有基本相等的功率,就像白光对所有频率的可见光具有相同的功率一样。
就像我们把不同频率的光称为不同的颜色一样,我们把不同频率的声音混合称为不同颜色的噪音。

phrase:
patterns within -> 模式内部:指在某个系统或数据集合中,存在着一些规律性的、可被发现的模式或趋势
air molecules -> 空气分子
broad range -> 广泛范围:指某一事物或概念所包含的广泛范围或领域。

audible
英 [ˈɔːdəbl]美 [ˈɔːdəbl]

adj. 听得见的

When we use our mouths to make a sound: "shhhhhhh," we get pink noise.

Pink noise is shaded more towards the low end of the spectrum.

That makes it a popular choice for people looking for background noise to drown out distractions.

Or to help them relax.

Although white noise has a flat spectrum, it can sound a little jarring and high pitched.

That's because our ears are more sensitive to the higher frequencies, so they feel louder.

Pink noise may be more soothing because it boosts lower frequencies, so it sounds more natural.

And it's similar to the background noise of our mother's womb -- a loud, low rumble.

The comforting sound of life itself.

translation

sentence:
当我们用嘴发出“shhhhhhh”这样的声音时,我们就会得到粉红色的噪音。
粉红噪声的阴影更多地向频谱的低端靠近。
这使得它成为人们寻找背景噪音来淹没干扰的热门选择。
或者帮助他们放松。
虽然白噪音有一个平坦的频谱,但它听起来有点刺耳和高音调。
这是因为我们的耳朵对更高的频率更敏感,所以它们感觉更响。
粉红色的噪音可能更舒缓,因为它提高了较低的频率,所以听起来更自然。
它类似于我们母亲子宫里的背景噪音——一种响亮而低沉的隆隆声。
生命本身的悦耳之音。

phrase:
drown out -> 淹没,压过
flat spectrum -> 平谱;帄波谱;平波谱
high pitched -> 高音调
comforting sound -> 令人感到安慰的声音:一种能够给人带来安慰和放松的声音,通常是柔和、温暖、柔美的声音。
