Most hearing aids are priced between $100 and $800.But in India, the world's second most populated country, the income per capita is around $600 a year.For many people there, airing aids are simply unaffordable.That was the problem.A student in the U.S. came up with a solution.It's a small device that could fit in someone's pocket.It works with headphones and it both tests a person's hearing and then becomes a hearing aid.
For two years, Mukund Venkatakrishnan spent hours fiddling with frequencies and tinkering with tones.
And two years is a long time, especially…
Because I'm only 16, like two years is a long time for me to spend on something.
This 16-year-old created this device, a hearing test and aid.
It eliminates a need for a doctor altogether.
First, the tests, different sounds at different frequencies.
You plug in head phones on the normal headphone jack right there.You hear the sound, you click the green button.If you don't hear the sound, you click the button.And after the hearing test is completed, the device program will start to be a hearing aid.
A double duty device, something even he wasn't sure that he could create.
I'm just surprised it turned out OK, right, because you never-it's hard to like see something like this working, like I wanted to quite a lot of times in the middle.
But besides his incredible persistence, there's a big reason why he didn't quit.
Summer after my freshman year, I went to India and I stayed with my grandparents.And my grandfather has had hearing loss for a little while.
And it became Mukund's job to help get him to a doctor for a hearing aid.And the experience was less than ideal.
And the process took forever to find an audiologist.Then, once we got there, they ripped us off.And so, I kind of looked into the problem more and that's kind of where I got into the idea.
So, when he got home from India, he went to work.
I started online. I looked up how to program online and I taught myself how to program.
And how to build a device at a price that more people can afford.
Yes, 60 bucks is what it is right now, and it's crazy that they cost $1,500 each when you can do it for 60 bucks.
Two years working on the project and he still plans on making improvements.
But then when you finally, I should get that solution, it's like the best feeling in the world, to finally break through and get that moment of ha-ha, like eureka.I love that feeling and it's kind of what kept me going-that and my grandfather.
This is one of the more relaxing Guinness World Records we've show you.All participants have to do really is lie down on a mattress.
It's the largest human mattress dominoes record.Twelve hundred people, 1,200 mattresses and 13 1/2 minutes of folks claiming a title by laying their sleepy heads.An appliance rental company set it all up in a 70,000 square foot conference center.The mattresses will be donated to charities.Maybe setting a world record isn't for everyone, but people were falling all over themselves for this one.
They all had a soft place to land.They easily put the record to bed after toppling the old one.There was just domi-no way they'd fail.
