Secret Ear Designer

Secret Ear Designer

Secret Ear Designer is a professional CAD platform dedicated to designing custom hearing aid shells, ear molds, and hearing protection devices. It takes 3D ear impression scans and outputs perfectly fitting ear pieces ready for manufacturing.

Core Capabilities

All Shell Types

Design every hearing aid form factor — In-The-Ear (ITE), In-The-Canal (ITC), Completely-In-Canal (CIC), Invisible-In-Canal (IIC), and Behind-The-Ear (BTE) molds. Each type has dedicated workflows and templates optimized for that specific geometry.

Automatic Shell Generation

Import a 3D ear impression scan and the software generates the shell automatically. It detects canal anatomy, creates proper wall thickness, and adds retention features — turning raw scan data into a functional shell shape in seconds.

Acoustic Vent Design

Place and customize vents for sound quality optimization. Choose from standard vent types or create custom paths based on audiological requirements. The software routes vents through the shell geometry automatically.

Component Placement

Position faceplates, receivers, microphone ports, and battery doors precisely on the shell. A built-in component library provides standard dimensions for hearing aid electronics.

Canal Modification

Trim, extend, smooth, and reshape the canal portion for comfort and retention. Build up or reduce material in targeted areas, and place wax guards and cerumen filters exactly where needed.

Surface Detailing

Add identification marks, serial numbers, and color coding. Create smooth transitions, rounded edges, and comfort features on the shell surface for a professional finish.

3D Print-Ready Export

Export shells as STL files optimized for SLA and DLP printers using biocompatible resins. Nesting tools support batch production for high-volume manufacturing.

Beyond Hearing Aids

Design swim plugs, noise protection molds, musician ear monitors, and sleep plugs using the same flexible workflow.

Scanner Compatibility

Import from all major ear impression scanners. Accepts STL, OBJ, and PLY file formats.

Who Benefits Most

Hearing aid manufacturers, audiology labs, ear mold producers, and hearing care professionals who design and produce custom ear pieces at any volume.
