Case Studies

ENGINEERING CLARITY:

Transforming Hearing Aid Fitting with Intuitive Software Solutions

Client Overview

Our client is an Italian hearing aid innovator with a strong international presence, producing 100% Made-in-Italy devices. Driven by values of transparency, credibility, and passion, their mission centers on advancing audiological knowledge and global hearing prevention. They partner with Havana’s Institute of Neurosciences, operating Latin America’s most advanced audiological center.

Challenges

The client required the development of the application software for a microcontroller-based
Electronic Unit. The project presented specific technical and procedural challenges:

Fragmented legacy software requiring excessive clicks for basic navigation

No role-based access control for different user types (admin/audiologist/developer)

Missing critical features: Autofit, Tinnitus management, and patient history tracking

Inability to configure hearing aids for different sound environments

Lost source code, preventing system upgrades or migrations

Our Approach

To address these challenges, we delivered a comprehensive software transformation:

End-to-End Workflow Design:

Created a unified patient journey:
– Patient
– Audiogram
– Device Communication
– Autofit

Role-Based Access System:

Implemented tiered logins with specialized permissions:
– Admin: Manages audiologist accounts
– Audiologist: Creates patient profiles and fittings
– Developer: Adds/configures hearing products

Advanced Clinical Capabilities:

Added 6 new features: Autofit, Tinnitus management, Patient History, Data Logging, Attack/Release, Frequency
Equalization

Technical Modernization:

Rewrote software using WPF
Framework (C#) with OnSemi
Rhythm hardware integration

UI/UX Revolution:

– Applied Adobe XD for user-centric interface design
– Implemented navigation principles: User control, cognitive load reduction
– Conducted visual research across leading hearing aid brands
