最近，全球网友因为一台微波炉的声效吵翻了天……

戳这里播放视频

起因是TikTok博主小哥Noel Doherty上周发布的一条视频，视频里小哥和朋友因为家里微波炉发出的声效音调到底是上升还是下降而吵了起来。



这条视频发布后立即爆火，在TikTok上一天内播放量就超370万。评论区里，“上升”派和“下降”派争论不休，还有人认为有上升也有下降……



TikTok user @noelbigdeal shared a perplexing video to his account on May 25 and in just one day has gained 3.7 million views and more than 700,000 likes. The clip shows Noel Doherty and a friend debating whether the microwave's bell-style alert goes up or down at the final note. 

Like the two friends, viewers of the TikTok clip haven't been able to reach a definite decision. More than 66,000 people have commented on the video, offering guesses including up, down and a mixture of both.

“微波炉音调之争”还“惊动”了美国歌手、音乐制作人“断眉”Charlie Puth……伯克利音乐学院科班出身的“断眉”，经常在TikTok分享自己制作音乐的视频，比如如何混音，如何添加各种合成器音效等等。

这回，“断眉”在个人账号发布了一条视频回应“微波炉小哥”，他在钢琴上弹出了旋律，并表示微波炉音调“第一遍是下降、之后一遍是上升”。



“断眉”的解释受到许多网友认可，他的回应视频播放量甚至超过了原视频，达550万。有网友评论说：“‘绝对音感（perfect pitch）’先生发话了，我们要支持！”



Social media users have, however, been able to get some sort of clarity from singer-songwriter Charlie Puth, who regularly posts videos on his TikTok account showing how his songs are made — exploring everything from choir singers to remixes and fake instruments.

Puth made a "stitch" video using the earlier clip, dueting with the microwave alert on his piano. "It goes down, and then up," he says as he plays, explaining that the first tone goes down, while the following one goes up. Puth's explanation seems to have made sense for many, with his video gaining over 800,000 likes and 5.5 million views — more than the original clip.

然而，也有网友评论表示，由于原视频里小哥和好友说话声太大，自己根本没听清微波炉的音效，“你俩要是不大喊大叫，我就能听清是啥音调了”……这条留言收获了两万多个赞。



之后，“微波炉小哥”只好又发布了一条视频，并连续播放多次微波炉音效。然而，不少网友表示：怎么好像听起来又不一样了……



就连“断眉”这回也改口了！他再次发布回应视频，表示有可能是该旋律的末尾音是个八度音阶（octave），导致大家产生分歧……最后他坚定的总结道：“总之，微波炉播放的三次音调都是上升的，第一次旋律的末尾音是个八度音阶”。



微波炉视频被网友搬到微博后，也引起了国内网友的“大战”。其中也有网友跟“断眉”持相同意见……




最终，这台微波炉品牌的官博出手了……

官博在Instagram发布声明表示，“是下降的，然而没那么简单……”！
 


之后官博给出了解释——这其实是一种叫“三全音悖论(Tritone Paradox)”的听力错觉，导致有人听到上升，有人听到下降……两种说法其实没有对错之分。



1986年，音乐心理学研究者黛安娜·多伊奇提出了“三全音悖论”。由一个三音或半八度音阶隔开的两个音调一遍又一遍地演奏，有些人会“听到”上升的音调，而另一些人会“听到”下降的音调。

研究表明，这两个声调的感知方式还会因为听者的语言和方言而异。例如，来自英格兰南部的人听到的音调和来自加利福尼亚的人听起来就不一样。

The tritone paradox is an auditory illusion in which a sequentially played pair of Shepard tones separated by an interval of a tritone, or half octave, is heard as ascending by some people and as descending by others. Different populations tend to favor one of a limited set of different spots around the chromatic circle as central to the set of "higher" tones. 

Furthermore, the way these tone pairs were perceived varied depending on the listener's language or dialect. In addition, Deutsch found that subjects from the south of England and from California resolved the ambiguity the opposite way.

怎么样，终于真相大白了吗？
