Restoring hearing with steerable electromagnetic fields
Backyard Creators is taking on an impossible neuroscience problem — restoring hearing for severe-to-profound loss without surgery and without an internal implant.
Today, restoring severe-to-profound hearing means surgery.
The current standard of care — the cochlear implant — demands invasive surgery and a permanent internal device. It carries surgical risk, is out of reach for millions, and forecloses future options once implanted.
Our goal is to restore hearing for people with severe-to-profound loss without cutting, without an implant, and without the lifelong limitations that come with both.
A multichannel, focused, controllable electromagnetic field.
Multiple EM fields Source that interfere constructively at a single depth — placing a focused, steerable stimulation point inside the auditory path. By tuning each channel, we move that focal point across auditory regions from outside the body.
Interfering channels concentrate stimulation where it's needed — not across the whole head.
Steerable and focused stimualtion by leverage EMF physics
A coordinated array delivers spatial resolution no single external source can achieve.
An experiment-driven framework, powered by Physics Intelligence.
We don't guess. Every hypothesis is evaluated by Physics AI-powered computational multiphysics, validated against real experimental data by physical EM lab setup, and carried step by step from simulation toward the clinic — with AI working alongside the underlying science at each stage.
Models predict field behavior across designs at scale.

The goal: restored hearing, non-invasively and further clinical applications investigation
Our work stands up to scientific scrutiny.
We present and defend our approach in front of the scientific community — at peer-reviewed conferences and in conversation with researchers across the fields our work touches.

From Madurai to Sound Hub Denmark.
Raman & Lakshmanan started with an aspiration most people said had no answer: restore hearing without surgery. We chased it out of a workshop in Madurai — and it took us to Sound Hub Denmark.
We're builders and physicists who would rather run the experiment than argue about it. That's how you solve an impossible problem
