先想一下你有生以来听过的最响
Think for a moment about how loud the loudest sound
的声音有多大
that you’ve ever heard in your life
如果你先听一段时间我的声音
Was if you’re hearing my voice right now after
感受了我的声音后
Experiencing an incident like that,
这种声音那可比人类在历史中
than it was nowhere near the loudest sound that has ever happened
所听见的的各种各样的甚至可以在几千公里
humans at various points in history have heard sound so loud
之外就能听见的巨大声响
from a source that they heard them from thousands of
差远了~
kilometers away from their actual origin
但在我开始介绍什么是那最响亮
But before I can explain what the loudest
的声音和它的惊人程度 让我首先来解释一下
sound was and how incredible it is I first need to explain
声音强度是怎么
How sound is measured in terms
被衡量的
of loudness in the first place
为了视频需要
This image here is a sound wave
这里有两张声波频谱
for the purpose of this video
了解声音的大小
All you need to know
你只需看它的振幅有多大
about really is the amplitude of the wave
因为振幅决定着*灰字:振幅长=声音大 振幅短=声音小*
Because it’s the amplitude that Determines
声音在人类指定的用来度量
How loud a sound appears to be to humans the
声音强度的分贝刻度上的大小
decibel scale is what’s used to measure the loudness of a sound
而且很重要的一点是这个分贝刻度表呈对数曲线
And it’s important to note that the scale is logarithmic
意思就是说10分贝的
this means that 10 decibels is
声音要比0分贝强上10倍
10 times more powerful than 0 decibels and
并且20分贝的声音也比10分贝强上十倍
20 decibels is 10 times more powerful than 10 decibels
但是比0分贝要强100倍
but 100 times more powerful than 0 decibels
了解了声音的度量
With all of that in mind let’s
让我们从10分贝开始到后面
start building our way up to the loudest
一直上升到人类所听见的最大声音
sound in history by beginning at 10 decibels
10分贝也勉强就是一个普通人
Which is about how loud standard human breathing
平均呼吸的频率
is and is barely audible to the average human
将上面的声音乘上10倍到20分贝
10 times more powerful than this at 20 decibels
是风吹过树林时发出的沙沙声 而再乘上10倍到30
Is the rustling of leaves in the wind and then 10 times more powerful
分贝是你说悄悄话的声音
than that at 30 decibels is a whisper
现在还是挺安静的
We’re still in pretty quiet territory,
所以让我们到更响亮的44分贝 也就是一个图书馆
so moving higher up to 44 decibels is the average ambient noise
里的噪音 更高一点到50
That’s present in a library a little bit higher
分贝是一个正常的室内交流的声音
than that at 50 decibels is the noise of a normal
再强上10倍到60
Conversation in your home and 10 times more powerful
分贝也就是一次正常的
than that at 60 decibels is the noise of a normal
在餐馆的一次交流的声音
conversation in a restaurant 70 decibels is
70分贝则是一个吸尘器所发出的声音强度
about the noise that a vacuum cleaner produces
这也为接下来要登场
And it’s a good comparison
的音量给了一个很不错的对比
for all the noises that are coming up next
吸尘器噪音
Twice as loud
的两倍差不多是一个垃圾处理场所产生的噪音
as that at 80 decibels is the noise created by a garbage
并且4倍于吸尘器
disposal and four times as loud
的声音也就是90分贝
as a vacuum cleaner at 90
是你离一个摩托车引擎启动时7.5米
Decibels is the noise that you would hear from a motorcycle engine
(25英尺)开外所听到的噪音
if you were seven and a half meters away from it
100分贝的声音相当于是吸尘器的8倍
100 decibels would be eight times louder
也差不多是一台手持式凿岩机工作时发出的噪音
than a vacuum cleaner and is roughly the noise produced by operating a jackhammer
凿岩机噪音的两倍则是
Twice as loud as that though at
110分贝 这也是人体开始
110 decibels is the average threshold
感觉到疼痛的临界点
that humans begin to experience pain at and
108至114分贝
108 to 114 decibels is the
平均是一场摇滚演唱会制造的噪音
average noise produced at a rock concert
我的一个在飞机模式下的(airplane
My friends over at airplane mode created a video
mode)朋友做了一个关于通过控制声音的各值来制作演唱会的视频
about the value of music produced at concerts like this
所以赶快确保在下方简介中看看
so make sure to check out their video
他的视频哦!
next in the description
电锯则能制造出
a chainsaw produces a noise of
120分贝的声音
120 decibels which is 32 times louder
也就是比吸尘器的噪音强上32倍 一支对你开火的霰弹枪
than the vacuum cleaner is a shotgun firing right next to you is about
可以发出130分贝的噪音
130 decibels and about the loudest noise
而你一生中所听过的最响亮的噪音大概就是一架
that you’ll probably ever likely hear in your life is a passenger
客机起飞距离你25米(82英尺)的声音
Jet taking off if you were standing 25 meters away
也就是差不多150分贝
from it which would be around 150 decibels
如果你的耳膜暴露在外面 这种声音强度可以
This is also the level of sound that can immediately rupture your eardrums instantly
立即震碎耳膜
if you’re ever exposed to it
可是我们一直到这人类
But the loudest sound ever heard by humans
所听过的最响亮的声音
that we’ve been building up to this entire time was
还要比这个更加难以置信地大~
unbelievably more loud than this
在1883年的春天 *事实上是夏天 播主搞错了 喷发日期在8月27日*
in the spring of 1883 the Volcanic Island
我们现在说的位于印度的喀拉喀托火山喷发
of Krakatoa in Modern-day, Indonesia
释放出了约两亿(2 000 000
exploded with the force of two hundred
000)吨的TNT当量 强大到甚至可以
Megatons a Force so powerful it
直接将这个岛屿夷为平地
Obliterated the entire Island
我在之前的一个视频里谈到了这次喷发
I’ve talked about this eruption before in a previous video
但我却没怎么讲喷发
But I didn’t spend much time talking
所产生的噪音
about the noise that it generated
任何一个超过194
any sound over
分贝的声音都会被归类成
194 decibels begins to Distort into more
一场爆炸所产生的冲击波
of a shock wave from an explosion
而不是声波
Rather than an actual sound wave
但是这场火山爆发 在喷发中心制造了约
but the krakatoa eruption generated an
310分贝的冲击波!
estimated 310 decibels at the epicenter of the explosion
这场冲击波强到甚至连 64公里开外的水手
This Force was so loud that sailors located 64
们的耳膜也被这冲击波震碎了 可是这冲击波
Kilometers away from the blast had their eardrums ruptured the noise was even louder
比你想象的还要强
though than this may seem at first
因为在距火山161千米(100英里)处
Because a pressure gauge located 161
的一个压力计测量到了一个
kilometers away measured a sound of
180分贝的声音
180 decibels it would have taken the sound
这个声音花了7分钟53秒
about 7 minutes and 53
才达到这里
seconds to reach that far from the Volcano
如果你站在那里
And it still would have been enough to
这种声音这不仅会导致你耳膜震裂
not only rupture your eardrums if you were standing there
还会一举将你
But also knock the wind
肺里的空气压出去、
out of your lungs and shatter glass windows on buildings.
将楼房的玻璃震碎
It’s possible
你甚至可能会
You could have actually died
死于这次声波对你的冲击
from the sound wave impacting and smashing through your body
如果你还是能幸免于难
But even if you didn’t you would
但我还能保证你会在后半生丧失听力
be guaranteed to be permanently deaf for life afterwards.
如果这场喷发发生在美国
If the sound from the blast originated
的纽约的中心公园的话
in Central park in New York City instead then
那么任何处于这个圈内的人都差不多会去世或
everybody located inside of this circle would either be Dead or
在后半生丧失听力
Permanently deaf for life afterwards
在现实生活中 这场火山爆发在澳大利亚的珀斯也还能听到
in real life the Volcanic blast was heard as far away as perth, Australia
那里的居民说他们听到了一声像霰弹枪发射的声音
Whose residents reported hearing what sounded like gunshots
这个声音甚至在4 800千米开外的印度洋的罗得
It was also heard on the Indian Ocean island of Rodrigues
里格斯岛也还能听到
4,800 kilometers away
那里的居民还以为这是大炮开炮 先想想一下如果
Whose residents reported what they believed to be cannon fire imagine
这时候你正站在中央公园里
if this time you were standing in Central Park
然后你听见了好像大炮在你身旁不知什么
And you heard what sounded like a cannon firing
地方开火的声音 然后你才发现这声音不是在
Somewhere around you only to find out later that the sound didn’t come
你附近产生的
from near you at all but rather
而是一直从爱尔兰传来的并且花了差不多
Came all the way from Ireland and it took a time
4小时才到达你的耳朵里
of nearly four hours to reach your ears
声波传播得越远
the sound wave began to grow less and
声音对人体就会越来越弱
less audible to humans the farther it traveled until the
直到声音频率变得太低以至于
Frequency became too low to be heard even
无法听见 可尽管人类自己听不见这声音
though the waves could it be heard by humans themselves
但是一些仪器检测到火山爆发
Past a certain range our instruments detected that the waves generated
的声波环绕了整个星球三圈
from the blast circled around the entire Planet
半!
three and a half times
所以如果你下次打开你的扬声器
So the next time you turn on your speakers
并把声音调得有点高
with the volume a little too high at least
可它至少也不会引发一场
it won’t be loud enough to cause
全球灾难啊 : )
a global catastrophe
广告时间:但如果你想要一个
But if you want a good speaker to listen to some
质量更好的扬声器
of these sounds at a more reasonable level
那为什么不看看Anker声核增益器呢~?(这广告插入的
Then why not check out the Anker sound core boost
…)你可以用它来听我或者其他你喜欢的频道的说话
you can listen to me or any of your other favorite
连续听12个小时
channels talk for up to 12 hours
也就差不多是喀拉喀托火山爆发的冲击波
Using this which is about how long it took the sound wave
到达圣地亚哥的时间
from the krakatoa blast to arrive in San Diego you
你可以用连续听250首不同的
Written this way for 12 hours listen to
歌12小时 而且这个扬声器还是防水的
250 different songs and since the speaker is water-resistant
肯定可以陪伴你一起共度
It would have lasted you for your entire
自驾游旅途 而且它有着两个
Journey it features dual drivers and twin subwoofers
20瓦的高音质低音炮
that delivers 20 watts of High quality audio
这意味着它所产生的声音可以
This means that can fill an entire room
布满整个房间 十分适合用于派对广播
with sound which is great for everything from podcasts to parties
它小巧玲珑的设计意味着你可以把它
It’s small minimalist design means that you can leave it
留在桌上也可以随身携带
on your desk or take it with you on the go
你还甚至可以通过一个USB线来给其他
And you can even power external devices
设备充电 这是Anker产品标签的特有电池
with a USB port packing Anker’s trademarked battery
充电技术 声核扬声器还有着18个月的保修时间
technology SoundCore Boost comes with an 18 month warranty and
和66英尺(20米)的蓝牙范围
66 Feet of Bluetooth range
