文本:
Crack detectors1 work by sound. If you get two good eggs and just tap them together, you get a nice ringing noise if it’s good or a dull noise if it’s broken. And on the machines, you’ve got sensors2 and they touch the egg 16 times, each egg. And it’s listening. It’s like a cotton reel. It moves up and down, listening to the noise it’s making. And it’s determining if it’s a good egg or whether it's cracked.
【翻译】
裂纹探测器通过声音辨别鸡蛋的好坏。你拿好鸡蛋,互相敲击,如果是好鸡蛋,你能听到悦耳的声音,如果是有裂缝的鸡蛋,就会听到浑浊的声音。这个机器上有传感器,它们会触碰每一只鸡蛋16次,并且分辨它的声音,就像棉花轴一样,敲击鸡蛋,然后分辨敲击发出的声音,决定哪个是好的,哪个是坏的。
