MinuteEarth, Why Doesn't All Thunder Sound The Same?

Why Doesn't All Thunder Sound The Same?

Thunder.

We've always been...well...thunderstruck by it, but for a long time, we weren't sure

what it was: the violent tantrum of a young god, the rumbling wheels of Thor's chariot,

or the flapping of a giant bird.

It wasn't until we got a handle on the science of both storms and sounds that we figured

out what thunder is and why it sounds the way - well, the many ways - it does.

Storms have a lot going on and we'll take a rain check on explaining most of it.

The key as far as thunder goes is that during a storm, positively and negatively charged

particles build up in different places, and then zig-zag through the air to get rebalanced.

During this rebalancing - which we know as lightning - a giant electrical current rushes

through a tiny channel of air in a fraction of a second, instantaneously superheating

the surrounding air.

And since increasing air's temperature also increases its pressure, that air gets super-pressurized,

causing it to explode outward in what we call a shockwave.

This sudden explosion is what we're experiencing when we hear a thunderclap - it's a distinct

sound that seems to come out of nowhere and contains an incredible range of frequencies.

Those same qualities are actually common to any abrupt and intense burst of pressure,

from the bang of a supersonic jet to the crack of a whip to the pop of a balloon to the snap

of a tiny bolt of static electricity; that's why all shockwaves sound surprisingly similar.

At least if you're nearby.

As a shockwave travels through the air, it loses energy and that intense burst of pressure

smooths out; what's more, the wave's higher frequencies dissipate more quickly than its

low frequencies.

So the farther away you are from lightning, the less sudden the onset of the sound is

and the lower the sound sounds - instead of a sharp “clap”, you might hear a resonant

“boom”.

Waves from more distant parts of the lightning bolt take even longer to reach you and can

overlap and echo off trees, hills, and clouds along the way, so you'll hear them as longer,

even lower-pitched rumbles.

And when lightning happens completely within a cloud, the waves start so far away and get

so jumbled up that all you might hear is a soft rolling sound, or nothing at all.

Within a single storm, lots of waves of pressure from lots of different parts of lots of different

lightning bolts intermingle and reach your ears at different times, so you'll often

hear a symphony of claps, booms, rumbles, rolls, and more.

It's a perfect storm of sound that launched a thousand origin - and Thor-igin - stories.

I started working on this video because during a summer storm, it suddenly struck me that,

despite knowing a thing or two about science, I had no idea what thunder actually was.

Why Doesn't All Thunder Sound The Same? Warum klingt nicht jeder Donner gleich? Why Doesn't All Thunder Sound The Same? ¿Por qué no todos los truenos suenan igual? Pourquoi tous les coups de tonnerre ne sonnent-ils pas de la même façon ? מדוע לא כל הרעם נשמע אותו הדבר? Perché i tuoni non hanno tutti lo stesso suono? なぜ、すべての雷の音は同じではないのか? 천둥 소리가 모두 같지 않은 이유는 무엇인가요? Kodėl ne visi griaustiniai skamba vienodai? Dlaczego nie wszystkie grzmoty brzmią tak samo? Porque é que os trovões não soam todos da mesma maneira? Почему не все звуки грома одинаковы? Varför låter inte all åska likadant? Neden Tüm Gök Gürültülerinin Sesi Aynı Değil? Чому не всі громи звучать однаково? 为什么不是所有的雷声听起来都一样? 為什麼雷聲聽起來不一樣?

Thunder. Trueno.

We've always been...well...thunderstruck by it, but for a long time, we weren't sure Wir waren schon immer … na ja … vom Donner gerührt, aber lange Zeit waren wir uns nicht sicher Siempre hemos estado... bueno... estupefactos por eso, pero durante mucho tiempo, no estábamos seguros Biz her zaman...iyi...bunun etkisi altındaydık, ama uzun bir süre, bundan emin değildik. 我们一直……嗯……对此感到震惊,但很长一段时间,我们都不确定

what it was: the violent tantrum of a young god, the rumbling wheels of Thor's chariot, qué era: la rabieta violenta de un dios joven, el ruido de las ruedas del carro de Thor, neydi: genç bir tanrının şiddetli öfke nöbeti, Thor'un arabasının gümbürdeyen tekerlekleri,

or the flapping of a giant bird. o el aleteo de un pájaro gigante. ya da dev bir kuşun kanat çırpışı.

It wasn't until we got a handle on the science of both storms and sounds that we figured Erst als wir die Wissenschaft von Stürmen und Geräuschen in den Griff bekamen, kamen wir auf die Idee No fue hasta que entendimos la ciencia de las tormentas y los sonidos que nos dimos cuenta Только после того, как мы разобрались в науке о бурях и звуках, мы поняли. Hem fırtınaların hem de seslerin bilimine hakim olana kadar öyle değildi. 直到我们掌握了风暴和声音的科学知识后,我们才发现

out what thunder is and why it sounds the way - well, the many ways - it does. herausfinden, was Donner ist und warum er sich so anhört - nun ja, auf viele Arten - wie er klingt. qué es el trueno y por qué suena de la manera, bueno, de muchas maneras, lo hace. выяснить, что такое гром и почему он звучит так, как - ну, многими способами - звучит. gök gürültüsünün ne olduğunu ve neden böyle ses çıkardığını - pek çok yönden - öyle olduğunu.

Storms have a lot going on and we'll take a rain check on explaining most of it. Bei Stürmen ist viel los und wir werden einen Regencheck machen, um das meiste davon zu erklären. Las tormentas tienen muchas cosas que hacer y haremos un esfuerzo por explicar la mayor parte de ellas. Во время штормов многое происходит, и мы не будем объяснять большую часть этого. Fırtınalar çok oluyor ve çoğunu açıklamak için yağmur kontrolü yapacağız.

The key as far as thunder goes is that during a storm, positively and negatively charged Der Schlüssel zum Donner ist, dass er während eines Sturms positiv und negativ geladen ist La clave en lo que respecta a los truenos es que durante una tormenta, la carga positiva y negativa Ключевым моментом в отношении грома является то, что во время грозы положительно и отрицательно заряженный Gök gürültüsünün anahtarı, bir fırtına sırasında pozitif ve negatif olarak yüklenmiş olmasıdır.

particles build up in different places, and then zig-zag through the air to get rebalanced. Partikel sammeln sich an verschiedenen Stellen und bewegen sich dann im Zickzack durch die Luft, um wieder ins Gleichgewicht zu kommen. las partículas se acumulan en diferentes lugares y luego zigzaguean por el aire para reequilibrarse. частицы накапливаются в разных местах, а затем зигзагообразно перемещаются по воздуху, чтобы восстановить равновесие. parçacıklar farklı yerlerde birikir ve sonra yeniden dengelenmek için havada zikzak çizer.

During this rebalancing - which we know as lightning - a giant electrical current rushes Während dieses Neuausgleichs – den wir als Blitz kennen – fließt ein riesiger elektrischer Strom Durante este reequilibrio, que conocemos como relámpago, una corriente eléctrica gigante se precipita Şimşek olarak bildiğimiz bu yeniden dengeleme sırasında dev bir elektrik akımı akar.

through a tiny channel of air in a fraction of a second, instantaneously superheating durch einen winzigen Luftkanal im Bruchteil einer Sekunde, augenblicklich überhitzt a través de un diminuto canal de aire en una fracción de segundo, sobrecalentándose instantáneamente через крошечный канал воздуха за долю секунды, мгновенно перегревая küçük bir hava kanalından saniyenin çok kısa bir bölümünde, anında aşırı ısınarak

the surrounding air. el aire circundante. çevreleyen hava.

And since increasing air's temperature also increases its pressure, that air gets super-pressurized, Y dado que el aumento de la temperatura del aire también aumenta su presión, ese aire se sobrepresuriza, А поскольку повышение температуры воздуха также увеличивает его давление, воздух становится сверхнапряженным, Artan havanın sıcaklığı da basıncını arttırdığından, bu hava süper basınçlı hale gelir,

causing it to explode outward in what we call a shockwave. haciendo que explote hacia afuera en lo que llamamos una onda de choque. şok dalgası dediğimiz şeyde dışa doğru patlamasına neden oluyor.

This sudden explosion is what we're experiencing when we hear a thunderclap - it's a distinct Esta explosión repentina es lo que estamos experimentando cuando escuchamos un trueno - es un claro Этот внезапный взрыв - это то, что мы испытываем, когда слышим раскат грома - это отчетливое

sound that seems to come out of nowhere and contains an incredible range of frequencies. sonido que parece surgir de la nada y contiene una increíble gama de frecuencias. звук, который, кажется, возникает из ниоткуда и содержит невероятный диапазон частот.

Those same qualities are actually common to any abrupt and intense burst of pressure, Esas mismas cualidades son en realidad comunes a cualquier estallido de presión abrupto e intenso, Эти же качества присущи любому резкому и интенсивному всплеску давления,

from the bang of a supersonic jet to the crack of a whip to the pop of a balloon to the snap desde el estallido de un avión supersónico hasta el chasquido de un látigo, el estallido de un globo y el chasquido от взрыва сверхзвукового реактивного самолета до треска кнута, от хлопка воздушного шара до щелчка.

of a tiny bolt of static electricity; that's why all shockwaves sound surprisingly similar. de un diminuto rayo de electricidad estática; es por eso que todas las ondas de choque suenan sorprendentemente similares.

At least if you're nearby. Al menos si estás cerca. По крайней мере, если вы находитесь поблизости.

As a shockwave travels through the air, it loses energy and that intense burst of pressure Cuando una onda de choque viaja por el aire, pierde energía y ese intenso estallido de presión Когда ударная волна проходит через воздух, она теряет энергию, и этот интенсивный всплеск давления

smooths out; what's more, the wave's higher frequencies dissipate more quickly than its suaviza; lo que es más, las frecuencias más altas de la onda se disipan más rápidamente que su

low frequencies. bajas frecuencias

So the farther away you are from lightning, the less sudden the onset of the sound is Entonces, cuanto más lejos esté del rayo, menos repentino será el inicio del sonido. Поэтому чем дальше вы находитесь от молнии, тем менее внезапным является начало звука.

and the lower the sound sounds - instead of a sharp “clap”, you might hear a resonant y cuanto más bajo suene el sonido, en lugar de un "aplauso" agudo, es posible que escuche una resonancia и чем ниже звук - вместо резкого "хлопка" вы можете услышать резонансный звук.

“boom”. "auge". "бум".

Waves from more distant parts of the lightning bolt take even longer to reach you and can Las ondas de las partes más distantes del rayo tardan aún más en llegar y pueden

overlap and echo off trees, hills, and clouds along the way, so you'll hear them as longer, se superponen y hacen eco en los árboles, las colinas y las nubes a lo largo del camino, por lo que los escuchará por más tiempo, перекрывают и отражаются эхом от деревьев, холмов и облаков по пути, поэтому вы будете слышать их дольше,

even lower-pitched rumbles. incluso retumba en tonos más bajos. даже более низкие звуки.

And when lightning happens completely within a cloud, the waves start so far away and get Y cuando los relámpagos ocurren completamente dentro de una nube, las ondas comienzan tan lejos y llegan

so jumbled up that all you might hear is a soft rolling sound, or nothing at all. tan revuelto que todo lo que puede escuchar es un suave sonido rodante, o nada en absoluto.

Within a single storm, lots of waves of pressure from lots of different parts of lots of different Dentro de una sola tormenta, muchas olas de presión de muchas partes diferentes de muchos В пределах одного шторма множество волн давления из множества различных частей множества различных

lightning bolts intermingle and reach your ears at different times, so you'll often los relámpagos se entremezclan y llegan a tus oídos en diferentes momentos, por lo que a menudo

hear a symphony of claps, booms, rumbles, rolls, and more. escuche una sinfonía de aplausos, auges, retumbos, rollos y más.

It's a perfect storm of sound that launched a thousand origin - and Thor-igin - stories. It's a perfect storm of sound that launched a thousand origin - and Thor-igin - stories. Es una tormenta de sonido perfecta que lanzó miles de historias sobre el origen y Thor-igin. Это идеальный шторм звука, который запустил тысячу историй о происхождении - и Тор-игин - истории.

I started working on this video because during a summer storm, it suddenly struck me that, Empecé a trabajar en este video porque durante una tormenta de verano, de repente me di cuenta de que, Я начал работать над этим видео, потому что во время летней грозы меня вдруг осенило,

despite knowing a thing or two about science, I had no idea what thunder actually was. a pesar de saber un par de cosas sobre ciencia, no tenía idea de qué era un trueno en realidad. Несмотря на то, что я кое-что знал о науке, я понятия не имел, что такое гром.
