evear-Key
Show patients exactly where hearing changes.
An interactive, anatomically grounded view of how sound travels — and where each type of hearing loss interrupts it. Built for the exam room.

Clinical convention
Red right. Blue left. The same language your patients already see on their results.
Educational, not diagnostic · Runs in any browser · Nothing to install · No patient data stored
Product proof
The real tools, running. Controls off.
Signed in, you set each ear, switch bone conduction and hearing aids, isolate a structure, and open full-screen on a tablet, laptop, or booth display.
Tools are served only to signed-in, subscribed clinics.
Second tool
Follow one tone all the way in.
Where a patient hears “nerve damage” and pictures nothing, this walks the tone through the canal, the eardrum, the ossicles and into the cochlear spiral — and lands on the exact turn where that pitch is detected.
Signed in: pitch, level, four loss patterns, an aid on and off, and a four-stage walkthrough.
What you get
A teaching aid that speaks your patients’ language.
Every control maps to something you already explain a dozen times a week — now they can watch it happen.
Four kinds of loss, side by side
Normal, conductive, sensorineural and mixed — set left and right independently to mirror a real audiogram and show where the signal breaks down.
Bone conduction vs. hearing aids
Show why the skull-bypass route restores conductive loss but not sensory loss — and why amplification helps where bone conduction can't. Clear expectations before a fitting.
Anatomically honest
Layered vector anatomy, red-right / blue-left convention, and sound from each ear crossing to the opposite side of the brain.
Exam-room ready
One click on a tablet, laptop or booth display. No install, keyboard accessible, and it respects reduced-motion for sensitive patients.
