Audiometric hearing screen (dementia-risk lever) — Amsterdam, Netherlands.

Amsterdam, Netherlands is the headquarters of Elsevier -- founded 1880, confirmed via WebFetch to Wikipedia -- which directly publishes The Lancet, the exact journal both this standard's citations (the ACHIEVE trial, Lin et al. 2023, and the Lancet Commission on dementia, Livingston et al. 2024) appeared in. No honesty-limit caveat needed: Elsevier is the direct publisher of the citations' own journal. Distinct from the existing Baltimore tile, which is built on the ACHIEVE trial's own literal research site (Johns Hopkins' Cochlear Center) rather than the citations' publishing house. 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, offered where the journal publishing both landmark citations is headquartered.

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.
