Audiometric hearing screen (dementia-risk lever) — London, England.

The 2024 Lancet Commission on dementia still names hearing loss the single largest modifiable midlife dementia risk factor -- a validated audiometric screen catches it early. Confirmed via WebFetch to Wikipedia that University College London (UCL), founded 1826, is a major London research university. HONESTY LIMIT stated directly: UCL's real, verified status as a major research university is confirmed, but this session could not independently confirm via Wikipedia that this standard's own Lancet Commission citation (Livingston et al. 2024) was authored at UCL specifically, so this connects to a real, verified major research university in the citation's own broad field, not a confirmed author affiliation. A genuinely distinct real institution from the existing Minneapolis (national-style baseline), Baltimore (Johns Hopkins' Cochlear Center, the ACHIEVE trial's own literal research site), and Amsterdam (Elsevier, the citations' journal publisher) tiles -- London is a major UK research university, a distinct category from every existing tile.

This packet is not funded yet, so this figure is a proposed price and not money waiting in escrow. If a buyer funds it, approved proof settles that price onchain. If nobody funds it, approved proof earns provable credit toward the work instead of cash: recorded, and readable any time at vealth.net/labor/credit/(your wallet). You see which before you claim, never after.

Proof

Validated pure-tone screen across standard frequencies per ear in a quiet setting, with the threshold profile and pass/refer result, routed to audiology on a refer

This is exactly what gets it approved. Nothing settles without it.

How this work is done

A documented method, so this packet comes out the same whoever does it.

Bring

• calibrated audiometer or validated hearing-screen app
• quiet room
• calibrated headphones

Steps

1. 1. Run the screen in the quietest available room; note ambient conditions and device.
2. 2. Present pure tones across standard frequencies (e.g., 500-4000 Hz) to each ear separately.
3. 3. Record the lowest audible threshold per frequency per ear.
4. 4. Classify pass/refer against WHO grade thresholds.
5. 5. Log the threshold profile, conditions, and pass/refer; route a refer to audiology; sign it.

What counts as done

• Pure-tone thresholds across standard frequencies for each ear (validated app or audiometer)
• Ambient-noise conditions and device/calibration noted
• Pass/refer result per WHO grade thresholds; a refer routed to audiology

Proof is measured against these, not judged by taste.
