Everyone should be able to obtain care, medication, or healthcare affordably. It seems Saad Bhamla took that concept and ran with it because he's created a dollar hearing aid that could revolutionize access for folks.

Saad is a bioengineer from Mumbai, India, and he created affordable hearing aids to help millions who are dealing with hearing problems. The idea popped in his head when he was an undergraduate, and he wanted to help his grandparents hear better. They both had problems with their hearing, but hearing aids were too expensive.

The idea that a person wasn't meant to hear simply because he or she didn't have the money didn't sit well with young Saad, so he decided to act. It might have taken some time, 15 years, but he's finally created a DIY hearing device. The device is made with parts that are available around the world, and a study shows that it helps tremendously.

It is estimated that over 200 million people are dealing with hearing loss due to age. For a long time, folks who were 65 or older had to deal with expensive hearing solutions, and some of these folks could never afford them.

On top of that, some people in certain places in the world don't have access to the right specialists. Saad has successfully given these folks their freedom and their lives back by fulfilling his dream to help.

Age-related hearing loss happens to folks after they hit a certain age. These people start to have trouble hearing high-pitched sounds like electronic beeps. This may not seem like a big deal, but when this happens, you also lose your ability to hear sounds like "s" or the "th."

Seniors, especially those living in countries where healthcare costs are expensive like in the United States, could end up paying $5,000 for these devices.

Well, this price is usually for custom hearing aids, but this type gives you optimal hearing. There is a lower grade option that costs $500, but even that is too much for most people around the world. Keep in mind that these could get lost or damaged.

Solving this problem was something Saad set out to do. He soldered a microphone to a small circuit board. This was done so that the device could capture close sounds. After that, he added an amplifier along with a frequency filter.

He made sure the filter was targeting anything over 1000 hertz, which is what these folks are having trouble with. Of course, Saad added controls so that the wearer could control the volume or turn the device on or off. The device has to be used with regular earphones.

The young inventor has made the plans available for anyone, and he says that a person can make them for about $15 to $20 if they want to. If a company were to do these in bulk, it would cost less than a dollar.

The device is called LoCHAid, and it's going to change hearing for many folks who need the help. The device might last about a year or a year and a half. The device can't be personalized to each person's hearing needs, but that's not the point. The device is meant to help folks who wouldn't be able to obtain hearing aids otherwise.

LoCHAid does show a lot of promise, but it hasn't been clinically-tested so you won't be able to purchase it just yet. Saad wants it to become available to folks soon, and he wants it to be a device you can purchase at the pharmacy just like you would purchase reading glasses as it should be.
