你戴降噪耳机时都发生过哪些好玩儿的事情？ 第1页

那是 N 年前的一天。

俺用着一个大约 4000 元人民币（900刀）左右的 APT-X 降噪耳机。

**题外话： 别再把中文书名号《》用在英文歌名、书名以及作品名上了好吗？

。。

大家一起到麦当劳去吃肉夹馍。

吃饱了回来， 老乡放了一个臭屁。

俺在听着耳机呢， 没想到不期而遇的臭屁让平时听惯了的音乐更通透， 三频更均衡了， 声场大了一圈， 感觉更宽松了。

俺没听到他吱声说对不起。

于是， 俺摘下耳机问：

“瘦子， 你是不是放了个大臭屁？ ”

老乡点了点头算是承认了。

Sennheiser MM550-X 的降噪效果确实太好了， 之前也没听到气流快速通过老乡的排气孔发出的鸣笛音， 应该也是被 MM550-X 耳机 Neutralized 了。

俺接着问， “你说说， 为什么屁会让俺耳机的音质突然变好？”

瘦子沉吟半晌， 说:

“屁这个东西牵涉到很多国家机密。

你知道吗？ 屁里面除了甲烷， 还有超导体。”

俺一下子精神振作起来，

“屁里面还有超导体？ 你别欺负俺没读过书啊。你说话得要有科学根据啊？”

瘦子板着脸，严肃地说:

“硫化氢是无机化合物，化学式为H2S。正常是无色、易燃的酸性气体，浓度低时带恶臭，气味如臭蛋；浓度高时反而没有气味（因为高浓度的硫化氢可以麻痹嗅觉神经）。2015年，物理学者发现，硫化氢在温度203K 极度高压的环境下发生超导相变，是目前已知最高温度的超导体。”

Why Stinky Fart Can Make Your Headphones Sound Much Better?

Author: BirdyBird

I own a pair of Sennheiser MM550-X, which comes with Sennheiser's NoiseGard™ technology 2.0.

One day my friend and me went McD for food.

After we came back to our dorm from McD, my old time buddy Sean cut the cheese in a stealthy fashion.

I was listening to my Hi-end Sennheiser MM550-X.

The unexpected odour of fart suddenly made my listening experience superb.

The bass, the mid and the treble became drop dead balanced and a lot more music details were unveiled. Tremendous amount of timbres gushed to my eardrums.

This is true music, I think.

This is unpresidented!!!

While I did not notice any apologetic vocal expressions from Sean, nor did I detect any wheezing or whoopee cushions sound that normally accompanies a fart during this significant sound reinforcement experience.

I took off my headphones and asked Sean,

“Hi bro, did you just let out a big fat stinky fart?”

my buddy blushed and nodded silently as a shy acknowledgment.

I kept going and asked,

“Tell me why your stinky fart makes my headphones sound different, please?”

Sean did not answer before a long break,

“Speaking of the fart, there are some state secrets involved and I am not sure if I am at liberty to disclose. You know, besides methane, there is some superconductor in my fart.”

I almost jumped up in joy,

“Superconductor in your fart? Never heard of it! Is it even scientific?”

Sean replied with a poker face,

“Hydrogen sulfide is the chemical compound with the formula H2S.

It is a colorless gas with the characteristic odor of rotten eggs.

It is very poisonous, corrosive, and flammable.Being heavier than air,

it tends to accumulate at the bottom of poorly ventilated spaces.

Although very pungent at first, it quickly deadens the sense of smell,

so victims may be unaware of its presence until it is too late.

At pressures above 90 GPa (gigapascal), hydrogen sulfide becomes a

metallic conductor of electricity. When cooled below a critical temperature

this high-pressure phase exhibits superconductivity.

The critical temperature increases with pressure, ranging from

23 K at 100 GPa to 150 K at 200 GPa.

And it is the superconductor known to human with the highest critical temperature as of now.”
