So how do you go about creating one of the world's most annoying sounds?
您当初是怎么设计出了这个所有人都最讨厌的声音的？
We started out by going out and getting recordings of actual sounds
一开始我们是去外面采集
that were in automobiles currently.
汽车自然发出的声音
Then we took those sounds back to the lab.
之后把采集到的声音带回实验室
Once they collected the sounds, it was time to test on people.
这些声音采集回来之后，需要在人身上进行测试
They created a system where the listener could
他们采用了一套设备，让听者能够
Play a sound and then put it in a category---
听一段声音，然后给它归类——
That the sound most represented.
按这个声音最显著的特点归类
Either a low urgency, like a Facebook notification.
要么归为分贝较低的提示音，就像Facebook消息提示那种
A medium range urgency, like a check engine alert.
要么归为中等分贝的提示音，比如提示检查引擎的那种提示音
And finally, a high level urgency like an oncoming collision warning.
又或是归为高分贝提示音，比如提示即将发生碰撞的警报声
And then from there we set up a series of driving simulator studies
在这个基础上，我们进行了一系列模拟驾驶研究
and they're driving along
受试者开着车，
and they're doing another task just to kind of give them a distraction component
同时还要完成其他任务，虽然设置这些任务只是想分散他们的注意力
and then suddenly, unexpectedly, the car that they're following would brake suddenly
突然，前车出其不意地停了下来
and we looked at their collision avoidance response on the timing of that.
我们就通过计时来测量受试者避免追尾的反应
They created the perfect forward collision warning alarm.
他们最后设计出来的，最令人满意的的预防与前车追尾的警报铃声就是这样
And this was really important because-- -
发明这个铃声非常重要，因为……
We found that the sounds being used currently
我们发现，目前所用的提示音
weren't perceived as being very urgent.
并没能让大家意识到情况有多紧急
You know, a poorly designed sound can be more dangerous than not having a warning at all.
你知道吗，一个设计不好的提示音要比完全没有提示音糟糕地多
So thanks for using the most annoying sound to keep us safe.
那……感谢您用最讨厌的声音保证了我们的安全。
