Wearable devices help people 'feel' sounds in their environment Neosensory's wrist devices provide vibrational feedback for sounds Contributed by Debbie Clason, staff writer, Healthy Hearing Last updated September 25, 20232023-09-25T00:00:00-05:00 What would it be like if you could feel sounds like doorbells ringing, alarm clocks buzzing, and water faucets accidentally left dripping? Neosensory's wearable wristband uses haptic technology to translate sounds into vibrations. New devices that turn sound into dynamic patterns of vibrations do just that, and they're helping those who are deaf or hard-of-hearing access vital information in a unique way. The company Neosensory now offers wearable devices resembling a wristwatch that mimic the ear’s cochlea by sending vibrations via the nervous system to the brain, effectively creating another sensory channel to the brain’s auditory processing center. Turning sound into unique vibrations Dr. David Eagleman, PhD, a Stanford University neuroscientist, and co-founder of Neosensory Dr. Scott Novich, PhD, began researching sensory substitutions for the Deaf in 2013. The technology they build essentially focuses on sending data streams to the brain through the sense of touch, known as haptic feedback. “The brain is locked in a vault of silence and darkness inside your skull, yet it constructs this whole world for us,” Eagleman explained, describing the eyes, ears and fingers as peripheral “plug and play” sensory devices. “Your brain doesn’t know and it doesn’t care where it gets the data from. It is fundamentally always trying to get information across the senses. Whatever information comes in, it just figures out what to do with it.” Adjustable settings via smartphone app The wearable devices can be programmed to user preferences. For example: Everyday mode adjusts to the user’s surroundings, canceling out unnecessary background noise. Sleep mode filters out sounds like snoring while still alerting the user to emergency sounds such as sirens or smoke alarms. Music mode allows users to feel the pulse of the beat along with nuances of the melody. The wearable also features an alarm setting, which users can customize with their desired vibration pattern. Approved for use for veterans In 2023, the Department of Veterans Affairs (VA) approved Neosensory's products (the Duo, Clarify and Buzz/Sound Awareness) to be distributed by audiologists for veterans with hearing loss and tinnitus. How these products differ from current assistive technology Assistive listening devices such as hearing loops, FM systems, infrared systems, and hearing aid accessories rely on amplification to deliver sound. Assistive alerting devices, such as bed shakers and flashing strobe lights, use touch and sight to alert users to alarm situations. There are also new smartwatch apps that identify sounds and display them as text on the watch face, such as the free SoundWatch for watches that use Google Android OS. Neosensory's products use sensory substitution to feed sound information directly to the brain through the skin. They benefit those who were born Deaf as well as those who were born with hearing but currently use hearing aids or other assistive listening devices. Users describe wearing the wrist devices as a tri-modal hearing experience. “They are seeing someone’s lips move, hearing something through their ears and they’re feeling vibration on their skin,” Eagleman said. “When they put all three of those channels together they get a really rich sense of what’s going on.” Related: Why you should learn to lipread when you're hard of hearing Clarify The Clarify product is intended for people who have high-frequency hearing loss. The device can be programmed to vibrate to indicate different high-pitched sounds. After several weeks, the brain starts to adapt and incorporates the haptic feedback into auditory pathways. Sound Awareness The Sound Awareness product is intended for people who are Deaf or severely hearing impaired. It can signal the wearer to important sounds like doorbells, water running, people talking, dogs barking, babies crying and so on. Duo The Duo is meant to help users adapt and habituate to tinnitus by training them to focus on external sounds. How much do they cost? Buying options range from $249/month for Duo (used short-term) or $999 for long-term use for Clarify and Sound Awareness programs.
