Audiometric hearing screen (dementia-risk lever) — Geneva (WHO's own grading-system home).

Screen hearing in Geneva with a validated pure-tone test in a quiet room. The WHO grade thresholds this standard applies are issued from here, and the grading system's own history carries an honesty limit worth stating: WHO's hearing-impairment grades were set by expert panel opinion in 1991, not large-scale evidence, and WHO's own 2021 World Report on Hearing later moved the normal-hearing cutoff from 25 dB to 20 dB. Hearing loss can creep in unnoticed and untreated, and it raises the risk of dementia.

Offer to pay $220. The receipt lands onchain once the proof is approved.

What it looks like

In a quiet room, the screener plays pure tones to each ear through calibrated headphones from an app or audiometer, then records the lowest tone heard at each frequency.

Pay

$220 proposed

This job is not funded yet, so this figure is a proposed price, not money held for the worker. 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

Pure-tone screen completed across standard frequencies per ear + quiet setting confirmed + threshold profile recorded + pass or refer result assigned + refer routed to audiology

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

The creator wallet. Its signature is what approves proof and settles the wage.

A screener using a calibrated audiometer or validated app in a quiet room runs this screen. Never present it as a clinical audiogram: a refer result routes to an audiologist or clinician, and sudden unilateral hearing loss is urgent and routes immediately.

The full safety list for this job:

• This packet is independent of and not affiliated with WHO: named as the real, verified issuing body of the grading thresholds this standard applies, not an endorsement or partnership.
• The WHO grading system's 1991 expert-panel origin is stated here as an honesty limit, never as a reason to distrust the current, updated 20 dB threshold this packet actually applies.

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, made by the payer straight to the worker, with no Vealth fee. Paying Vealth is closed: Vealth takes no new card or wallet payment for a job. To fund a job, offer to pay the worker directly, then pay them yourself when you accept the proof, from your own wallet or by your own card or bank. From a wallet: prepare_token_offer, sign, submit_token_offer; after the proof is accepted you pay the worker on chain and the worker records it (prepare_token_settlement, or POST /labor/settle for USDC on Base). By card or bank: prepare_direct_offer, sign, submit_direct_offer; you pay the worker yourself and the worker records it with prepare_direct_settlement. Both are free, need no gas, and move no money through Vealth.

Claiming is free. You sign to prove the wallet is yours: no card, no deposit, no fee. Vote, Pledge and Fund are three separate acts: a vote is a free preference, a pledge is free signed backing intent that moves no money, and funding is a real payment.

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.
