I actually feel like there's some real information in them that can be exploited for the purposes of helping people with rehab.
“实际上我认为这些声音中包含的一些的信息可以为患者所用并且有助于他们康复。”

Inan's experience with cracking knees goes back to his days as an undergrad at Stanford, where he threw discus.
伊恩楠的膝盖创伤经历要追溯到他在斯坦福大学的学生时代，他就是在那里开始讨论这项实验。

If I had a really hard workout, then the next day of course I'd be sore, but I'd also sometimes feel this catching or popping or creaking every now and then in my knee.
“我要是刻苦进行训练，第二天膝盖就会非常痛，但有时我也会感觉膝盖发出咯吱咯吱的声响。

A few years later, he found himself building tiny microphones at a high-end audio company.
而几年后他在一家高端音频公司制造了微型麦克风。

So when he got to Georgia Tech and heard the Defense Advanced Research Projects Agency, DARPA, wanted better tech for knee injuries, he thought:
因此当伊恩楠来到佐治亚州理工学院并听说到DARPA，即美国国防部高级研究计划局的这项工程后，他希望能研发更先进的技术来治疗膝伤，于是他想:

Why not strap tiny microphones to people's knees, to eavesdrop as their legs bend?
“为什么不把微型麦克风植入人体膝盖记录下膝盖弯曲发出的声音呢？”

What we think it is, is the cartilage and bone rubbing against each other, the surfaces inside the knee rubbing against each other, during the movements.
我们认为发出声音是因为软骨和骨头相互摩擦所致，而运动的过程中，膝盖内部这两者的表面会相互摩擦。

He and a team of physiologists and engineers built a prototype with stretchy athletic tape and a few tiny Mics and skin sensors.
他和他的生物学家及工程师小组用弹性透气胶带、一些微型麦克风及皮肤传感器建立了一个原型。

And preliminary tests on athletes suggest the squishy sounds the device picks up are more erratic, and more irregular, in an injured knee than in a healthy one.
而对运动员的初步测试表明，同健康膝盖相比，受伤膝盖中所侦测到的声音更加不稳定，也更无规律可循。

Which Inan says might allow patients and doctors to track healing after surgery.
伊恩楠表示这项技术可能会让病人及医生手在术后进行追踪治疗。

The primary application we're targeting at first is to give people a decision aid during rehabilitation,
我们进行这个项目的主要目标人群是患者的膝盖受到严重创伤后

following an acute knee injury, to help them understand when they can perform particular activities, and when they can move to different intensities of particular activities.
首先要让他们知道，在康复期间何时可以进行特殊活动及何时可以增加强度。
