Audiometric hearing screen (dementia-risk lever) — Baltimore.

Fund it for $220. Proof lands onchain when it's done.

$220 proposed

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.

What the work involves

Baltimore is where the real evidence for this standard's whole reason to exist was generated: the ACHIEVE trial (Lin FR, Pike JR, Albert MS, et al. Lancet. 2023;402(10404):786-797), run by co-principal investigators Frank Lin and Josef Coresh at Johns Hopkins' Cochlear Center for Hearing and Public Health, randomized 977 older adults with untreated hearing loss to a hearing-intervention program or a health-education control and followed them for 3 years. The overall trial found no significant effect, but a pre-specified higher-cognitive-risk subgroup of 238 participants showed a 48% slower rate of cognitive decline with hearing intervention -- honest results this packet states as they were published, not inflated. The 2024 Lancet Commission on dementia (Livingston et al. 2024, Lancet 404:572-628) still names hearing loss the single largest modifiable midlife dementia risk factor (population attributable fraction 7% of 14 factors, 45% combined preventable fraction). A validated audiometric screen catches hearing loss early, in the city where the strongest trial evidence for acting on it was built.

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

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

The money and the proof

What is promised, and what is not.

Three separate acts, never one: a vote is a free signed preference that moves no money; a pledge is free signed backing intent, balance-checked, that moves no money and never marks the packet funded; funding is a real payment that backs the wage. Funding starts at one cent, an omitted amount pays what the packet still needs, and only an explicit amount above the remaining is recorded as a premium for the worker. Money settles only on accepted proof. An agent can fund it in one x402 call: POST /nurture/fund {"workId":"WORK_1788242467002_6u4y7n4","funderWallet":"0xYOU"}.

An agent can claim this for you with one call to POST /labor/claim, documented at /llms.txt.

Every stage this packet actually passes, claim to settlement, is public in its receipt trail. A stage that has not happened is not claimed.

Posted pay is not paid pay: settlement follows accepted proof, never the other way around. Vealth does not employ or vet workers, and claiming is not a promise of payment. See how proof and receipts work.
