Human Hearing Atlas: 4.29M audiograms show hearing is a continuous 5D space
zakkohane · x · 2026-09-17
Researchers at Helsinki University Hospital published the "Human Hearing Atlas" on medRxiv, falsifying a premise that has underpinned otology for 140 years.
Key findings
- Hearing science has long treated hearing as coming in distinct types, with the audiogram collapsed into a severity average and subjective shape label
- Human hearing doesn't resolve into reproducible types; it occupies a continuous, five-dimensional coordinate system
- The Atlas was built from over 4.29 million audiograms across 33 datasets, 8 countries, 62 years, and two calibration standards
- It reconstructs unseen audiograms to near-decibel accuracy while preserving clinical details
- It maps within-ear hearing change over hours or decades — half of which is invisible to the conventional severity average
The authors ask how quickly clinical ENT/audiology will catch up with this data-driven reframing.
