Levitate with sound- Get the hoverboard

hoverb

This Kickstarter project is the first in my series that will teach you the science needed to develop your own technologies in a particular field of interest.

This project focuses on SOUND and more importantly, ultrasonic levitation.  No, this isn’t some kind of free energy or anti-gravity gimmick.  This is real science that works and the videos prove it.

I have always been fascinated with sound and while experimenting with one of my previous Kickstarter projects, Soundlazer, I came across the amazing principle of ultrasonic levitation.   I was surprised to find out that there were no kits or completed circuit designs available on the internet so I decided to bring this project to the Kickstarter community.

Fighting Fire with Sound?

What’s New, Future Trends
By Daniel Meyers

Fire wears the dual hat of being both our friend and our enemy. Necessary for advanced life, and equally potent to end it, it’s the latter point that has led to finding better and better methods for extinguishing it. Water, chemicals, even blankets…fire suppressants have taken many forms. And now, the practice of fighting fire with sound is showing incredible promise as an effective, fire-fighting tool.

Watch here how students at George Mason University demonstrate a fire-suppressing sound device to extinguish flames.

Hearing Conservation Program-Yes -No?

The first step toward solving any noise problem is to define it. To understand what requirements must be implemented according to OSHA’s noise standard [29 CFR 1910.95, it is necessary to determine exposure levels. The following sections provide information about evaluating noise exposure levels:

Indications of a Problem
Walkaround Survey
Workshift Sampling
Instruments Used to Conduct a Noise Survey (App III:A)

Listen Up! Noises Can Damage Your Hearing

Sounds surround us. We enjoy many of them—like music, birdsong, and conversations with friends. But loud or long-lasting noises—from motors, power tools, and even headphones—can permanently damage your hearing. Take steps to protect your ears from harmful noises.

Loud noise is one of the most common causes of hearing loss. An estimated 26 million Americans between the ages of 20 and 69 already have irreversible hearing loss caused by loud sounds. And up to 16% of teens have hearing loss that may have been caused by loud noise.

“Noise damage can begin at any age, and it tends to accumulate over time. That’s why avoiding excess noise is so critical,” says Dr. Gordon Hughes, a clinical trials director and ear, nose, and throat specialist at NIH. “Hearing loss caused by noise is completely preventable.”
