These “Headphones” Convert Sound Into Vibration So The Deaf Can Experience Music

“Music is one of the deepest and most primal forms of human communication”

When it comes to sound—particularly recorded and live music—we take vibration for granted. But attend a flamenco performance or go to a My Bloody Valentine concert (as I like to), and you’ll understand what it’s like to feel those vibrations in your bones.


Liron Gino, an industrial designer and recent graduate of the Bezalel Academy of Jerusalem, took this to heart with her recent creation Vibeat—headphones and other accessories designed for the hearing impaired. Vibeat takes sound and music and converts the waveforms into vibrations fine-tuned for the body to feel, rather than hear.

“Music is one of the deepest and most primal forms of human communication, and its ability to convey emotion and expression make it into an invaluable tool,” Gino said in a statement. “However, there are those among us who do not share these mutual experiences.”

Gino tells GOOD that Vibeat spun off from conversations she’d had with individuals in the deaf and hearing-impaired community for an unrelated project—Gino would ask about their day-to-day experiences, and much to her surprise, one of the most frequent topics turned out to be music.

In researching how to convert sound into a different sensory medium, Gino looked for inspiration in the ways that audio has been visualized. She also studied the phenomena of sound waves interacting with water, producing fluid waves. Gino thanks the Canadian-based company StudioFeed for the lessons she learned from its “tactile bass system” SubPak, which converts sound into vibrations to be felt by the body.

“Throughout the entire design process, I would meet and discuss various elements of the product with hearing impaired people,” Gino says. “[They] helped me to understand their needs and desires. I realized [Vibeat] would have to provide a parallel sensory experience to that which a hearing person might have when using a portable music player with headphones.”

The product would therefore need to be compact, portable, gender-neutral and desirable, allowing several options for placement on the body—why stick to the ears? Gino also hoped that Vibeat would appeal to those who could hear.

“The human sense of hearing is very unique in that it can sense and comprehend a very large range of frequencies,” says Gino. “The sense of touch, however, is less sensitive in that respect, and most people can only feel a small fraction of the frequencies which they can hear—namely, bass frequencies.”

“Therefore,” she adds, “a simple mechanism which would convert an audio signal to a vibration of identical frequency would not suffice in providing a true representation of all that we can hear. To try to address this problem, I had the entire range of heard frequencies modeled and ‘re-scaled’ to fit within the frequency range that the body can feel.”

First, the audio signal is fed into Vibeat through Bluetooth technology. Then the signal is analyzed and rescaled in real-time, then fed through to vibration motors, with different motors reacting to different frequencies. If a user pairs two Vibeat units, he or she can decide that each unit should convey a different frequency range. One unit might handle bass frequencies, while the other could focus on high frequencies. Alternatively, Gino says that both units can be configured to convey the same feeling (an identical representation of the full frequency range, for example), making it possible for two people to share the same experience.

After Gino demoed a working Vibeat prototype at the Bezalel Academy of Arts exhibition, she says the demand has been exciting; at the moment she is “working on refining and further developing the product.”

Young leaders from around the world are gathering at the United Nations Headquarters in New York Saturday to address arguably the most urgent issue of our time. The Youth Climate Summit comes on the heels of an international strike spearheaded by Greta Thunberg, the 16-year-old climate activist from Sweden, who arrived in New York via emissions-free sailboat earlier this month.

Translated from Swedish, "berg" means "mountain," so it may feel fated that a young woman with Viking blood in her veins and summit in her name would be at the helm. But let's go out on a limb and presume Thunberg, in keeping with most activists, would chafe at the notion of pre-ordained "destiny," and rightly so. Destiny is passive — it happens to you. It's also egomaniacal. Change, on the other hand, is active; you have to fight. And it is humble. "We need to get angry and understand what is at stake," Thunberg declared. "And then we need to transform that anger into action."

This new generation of activists' most pernicious enemy is denial. The people in charge — complacent politicians and corporation heads who grossly benefit from maintaining the status quo — are buffered from real-life consequences of climate change. But millions of people don't share that privilege. For them, climate change isn't an abstract concept, but a daily state of emergency, whether it comes in the form of "prolonged drought in sub-Saharan Africa…devastating tropical storms sweeping across Southeast Asia, the Caribbean and the Pacific…[or] heatwaves and wildfires," as Amnesty International reportsare all too real problems people are facing on a regular basis.

Millions of people in over 150 countries across the globe marched for lawmakers and corporations to take action to help stop climate change on Friday, September 20.

The Climate Strikes were organized by children around the world as an extension of the of the "Fridays for Future" campaign. Students have been walking out of classrooms on Fridays to speak out about political inaction surrounding the climate crisis.

"We need to act right now to stop burning fossil fuels and ensure a rapid energy revolution with equity, reparations and climate justice at its heart," organizers say.

There's no doubt the visual images from the marches send a powerful message to those on the ground but especially those watching from around the world. GOOD's own Gabriel Reilich was on the scene for the largest of the Climate Strikes. Here are 18 of the best signs from the Climate Strike march in New York City.

September 20th marks the beginning of a pivotal push for the future of our planet. The Global Climate Strike will set the stage for the United Nations Climate Action Summit, where more than 60 nations are expected to build upon their commitment to 2015's Paris Agreement for combating climate change.

Millions of people are expected to take part in an estimated 4,000 events across 130 countries.

When the iPhone 11 debuted on September 10, it was met with less enthusiasm than the usual iPhone release. A lot of techies are holding off purchasing the latest gadget until Apple releases a phone with 5G technology.

Major US phone carriers have yet to build out the infrastructure necessary to provide a consistent 5G experience, so Apple didn't feel it necessary to integrate the technology into its latest iPhone.

A dramatic new feature on the iPhone 11 Pro is its three camera lenses. The three lenses give users the the original wide, plus ultrawide and telephoto options.

We often dismiss our dreams as nonsensical dispatches from the mind while we're deep asleep. But recent research proves that our dreams can definitely affect our waking lives.

People often dream about their significant others and studies show it actually affects how we behave towads them the next day.

"A lot of people don't pay attention to their dreams and are unaware of the impact they have on their state of mind," said Dylan Selterman, psychology lecturer at the University of Maryland, says according to The Huffington Post. "Now we have evidence that there is this association."
