The studies used FOX fitting software in 2022 and 2023. The sources do not establish whether this was the later AI-FOX generation.

Inputs and outputs

Not assessed

Autonomy

Not assessed

Workflow

Outcome measurements (thresholds, loudness scaling, speech scores) fed to the FOX recommender. Audiologists applying the recommended MAPs.

Human oversight

Not assessed

Relation to AI

The software proposes MAP settings from measured outcomes. The trials compare it with manual fitting and attribute the measured gains to the FOX maps. All three papers share co-author P. J. Govaerts. The developer's identity is taken from Otoconsult's own site. No record independent of the authors' group is among the sources.
