百科知識視頻之煎蛋小學(xué)堂26 敢不敢相信你的耳朵

Many of us have become quick to catch illusions that trick your eyes,but how often do you consider illusions of the ear?Are you really able to trust your ears and the things they hear? For example,listen to Greg speaking.what do you hear?If you heard "Bar,Bar,Bar",you'd be right.But,how about now?Chances are,you heard "Far,Far,Far"this time,with an F.Except,you didn't.In fact,the audio didn't even change between the two videos.Strange as it may seem,what you hear depends on which video you're looking at.

有很多人都能一眼看穿視錯覺，不過你考慮過聽覺錯覺嗎?你真的能相信耳朵 以及 它聽到的東西嗎?舉個例子 聽聽Greg說話。你聽到了什么?如果聽到“Bar Bar Bar"就對了。不過 現(xiàn)在呢?有可能 你這次聽到的是含有F的“Far Far Far".不過 你沒有。其實(shí) 兩段視頻中的音頻并未改變。這似乎有些奇怪 你聽到的聲音取決于所看的視頻。

Go ahead,take turns watching each video and see how the sound morphs.This is the perfect example of something called the "McGurk Effect",which shows how our visuals can alter what we believe we're hearing.Now I want you to count how many time you see a circle flash on screen.Let's do that one more time.Did you see it flash twice?Many people do,Yet,without the sound,it becomes clear that the circle is only flashing once.

斷續(xù)試試 輪流看各個視頻 感受下聲音的變化，這個例子完美地詮釋了“McGurk效應(yīng)”，它說明 我們的所見可以改變自以為聽到的東西，現(xiàn)在我想讓你來數(shù)一數(shù)，屏幕上看到幾次閃爍的圓，再來一次，你看到兩次 是么?很多人是這樣，而去掉聲音則能清楚地看到圓只閃過一次。

In this case,the sound has altered your perceived vision.The next one works best with other people around.I'll play two tones,and you tell me if they are ascending or desending.In other words,are the notes played from low to high or high to low?Listen to this,Which was it?How about this one?Write down what you heard fro each number and let us know in the comment.

在這里 聲音改變了你的所見，下一個例子最好與其他人一起做，我會播放兩種音調(diào)，你來告訴我，音調(diào)是上升了還是下降了，換句話說 它們的調(diào)子是從低到高還是從高到低，聽好了，是哪個呢?這一個呢?寫下你對每個例子的答案 在評論中留下你的高見。

Chances are,if you compare with enough people,you'll all have different answers.Surprising?Try some more.And this one.How is it possible that you are hearing something different from others?It's an auditory illusion called the "Tritone Paradox".It's created in such a way that the tones contain both a higher and a lower frequency in them but our brains have a preference of which to listen to.Diana Deutsch,the creater of this illusion found that your geography and language from infancy,all play a role in deciding this preference.

很可能 如果你同足夠多的人比較，你們每個人的答案都不同，震驚了 再來幾發(fā)，還有這個，你所聽到的怎么會和其他人的不同呢?這是一種錯聽 即“三全音悖論”，它是通過某種音調(diào)中包括，一個高頻和一個低頻聲音產(chǎn)生的，但我們的大腦偏愛于聽某一種聲音，錯覺創(chuàng)作者 Diana Deutsch,發(fā)現(xiàn) 人的地理位置和自出生以來的語言，都決定著這種偏好。

Finally,listen to this audio clip of a gradually climbing tune.And yet,if I play the exact same clip back to you,if will sound like it's only continuing to climb higher and higher.I swear this is the exact same clip I just played.You can rewind that section of this video over and over and check for yourself.Try it?Each time you started over,the tune is seemingly climbing even higher.

最后 聽聽這段逐漸升高的旋律，如果我把同一段視頻再放一遍，聽上去音調(diào)只會越爬越高，我發(fā)誓 這高是我剛才播放的片段，你可以一遍遍重放那段視頻 自己驗證，試試吧，每次從頭開始后，旋律總會聽上去越升越高。

It's called the "Shepard Tone Illusion"of which there are many variations.In it,multiple sine waves are played on top of one another,raising in pitch,while one quickly drops down an octave as the others continue rising.But our brain doesn't know this drop,so the clips sound like they are rising forever.These illusions may help to explain how something like music.can have such a profound yet varying effect on our minds.which we discussed in our new AsapTHOUGHT episode.

這被稱為“Shepard音錯覺”它的變體很多，其中 多個正弦波相互疊加 音調(diào)逐漸升高，而其中一個迅速下降八度 其他音調(diào)仍在上升，但我作的大腦未注意到降調(diào)，因此視頻(的音調(diào))聽上去在不停上升，這些錯覺可以幫助解釋 音樂等事物是如何對我們的思想產(chǎn)生多種且深遠(yuǎn)的影響，我們在新一期Asap THOUGHT 中加以討論。

Here,along with the question of "Whether or not music can save your life".

在這里 連同新問題“音樂是否能拯救生命”。
