CORGEE

Discover

The first objective hearing test with natural speech

An objective test that maps brain responses to everyday sound, speech and language — enabling audiologists and ENT specialists to assess speech processing and hearing device benefit without active patient participation.

CORGEE is CE certified as a medical device and has been clinically validated in 100 children with hearing aids and/or cochlear implants – in partnership with the University Hospital of Leuven and three regional children’s hearing rehabilitation centers.

Why CORGEE?

The missing link in modern audiology

Current hearing tests either require active participation, or rely on unnatural stimuli like tones and isolated vowels — offering little insight into how a child actually understands speech. CORGEE changes that.

Infant wearing EEG cap during a measurement

Objective

State-of-the-art technology based on brain responses. No active participation required — particularly suited for patients who are difficult to test behaviorally.

Clinician reading a picture book with a toddler

Realistic & child-friendly

Higher engagement and motivation, thanks to the use of age-appropriate films and stories. No standardized speech materials needed — results reflect listening in everyday life.

CORGEE software and consultation with parents

Made for clinicians

Direct insights into speech processing with and without hearing devices — supports counseling and communication with caregivers, building confidence in rehabilitation decisions and informed device fitting.

How it works

Three simple steps

01

Easy set‑up

Input patient data, mount the EEG cap, and verify electrode quality using real-time visual feedback.

Setup
02

Efficient procedure

Child-friendly protocol with age-specific, well-calibrated stimuli. Results are available immediately during the session.

Procedure
03

Intuitive report

Objective results based on brain responses, with intuitive visualization of hearing aid and/or cochlear implant benefit.
