Hundreds of millions of people around the world have lost their hearing. In Africa, Dirk Koekemoer wants to help by getting them to sit in the shade of a tree.
It was an idea that inspired a doctor to walk out of his practice. Dirk Koekemoer, the founder of biomedical engineering company eMoyo, spent the next 18 years building a device that helps tens of thousands to hear – all they have to do is sit under a tree and listen.
"It was 1999, I literally sat in practice and realized this is going to go on forever. I was going to see 30 patients a day for the rest of my life. I wanted to be able to treat thousands. I cancelled all my appointments that day and took the bold move to start a company," says Koekemoer.
It cost Koekemoer $1.2 million and saw the birth of the KUDUwave, a mobile audiometer that looks like a set of headphones. Its size and the fact you can use it under a tree made it a game changer.
"A basic sound booth, at minimum, would cost R35,000 ($2,600). They can be the size of a fridge and are good for screening. But, the moment you want to do proper audiology the booths go up to R250,000 ($18,700). Then the moment you look at mobile audiology you need two booths on a mobile trailer, with a 4x4 and on a heavy trailer. You are looking at costs of R500,000 ($37,000)."
The R65,000 ($4,800) headphones are cheap and smart. They won’t operate unless the conditions are just right. One of the best places to use them is under the shade of a tree, just as well as Africa has plenty of them. They are used in the rural areas, like Zambia, where audiologists need to get around. "Open air testing, in an area with open windows or under a tree, is the best for ear testing. A booth needs ventilation, it needs soundproofing and probably doubles the costs."
"There are 3.5 billion people in the world that don't have access to adequate equipment. I thought let's create devices that can actually do the tedious things that a doctor and a nurse have to do that don't need brainpower," says Koekemoer.
