Advanced Textiles Source mentioned Wave Sciences' advances in consumer hearing in a recent article on smart textiles (link):
“Our garment is a hands-free, discreet solution to hearing-in-noise—nobody knows you are wearing it. Currently, all of the electronics are removable for laundering the garment, but we are moving to the next step in our development where everything but a small, detachable module is washable,” he says. “It will feel like a common undergarment.”
“We can make hearing ten times better,” McElveen continues. “If someone needs to be within two and a half feet to easily have a conversation within a coffee shop, we let them hear their order being called out by the barista across the room, 25 feet away. That changes peoples’ daily lives.”
