The sound of a cracking knee isn't particularly pleasant.
But it gets worse when you listen up close.
"It does for most people. But for me, it just makes me excited."
Omer Inan, an electrical engineer at Georgia Tech.
"I actually feel like there's some real information in them that can be exploited for the purposes of helping people with rehab."
Inan's experience with cracking knees goes back to his days as an undergrad at Stanford, where he threw discus.
"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."
A few years later, he found himself building tiny microphones at a high-end audio company.
So when he got to Georgia Tech and heard the Defense Advanced Research Projects Agency, DARPA, wanted better tech for knee injuries, he thought:
Why not strap tiny microphones to people's knees, to eavesdrop as their legs bend? "
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."
He and a team of physiologists and engineers built a prototype with stretchy athletic tape and a few tiny Mics and skin sensors.
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.
Which Inan says might allow patients and doctors to track healing after surgery.
Details appear in the IEEE Transactions on Biomedical Engineering.
"The primary application we're targeting at first is to give people a decision aid during rehabilitation, 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."
A useful thing to take a crack at.

膝盖裂开的声音肯定不是令人特别愉悦EqVP91MGJ)HG!xQ。
但是你靠近听时，声音就会更刺耳DjoJ)cEXEM6#9jVu#Wcw。
“很多人都是这样的感觉，但对我而言，这种声音只会让我更为兴奋p5n!LAfYZqO。”
佐治亚州理工学院的一名电气工程师奥默尔•伊恩楠说道=LI4(L0odKl0en0I5。

“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SO.(OI+PWo)。”
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LXVRvcvrlXli18=tT,ZI。
“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nZel)bG=d]vKC*~H2JD。
而几年后他在一家高端音频公司制造了微型麦克风,Jrtfn&M%41。
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:
“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？”
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=JqEcmlY=lM(qD^。
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rD-uTA*~Bm~_8-Z。
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kR@bgeQ2cSX。
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8Fw[WLY;%euN]。
这项研究已在《IEEE生物医学工程》杂志上发表thqhRs@NeHhy。
“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，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Yg87g|NXgV。
这种追踪会非常有用0L%Yeus)2QxzoR2。
