Jobs change. Test providers change. A worker’s hearing history should follow them.
Ouïvia — Hearing Pathway — is our offline-first Field and Office platform for occupational audiometric testing. Built around the employer appointment and the worker’s continuing hearing history. Starting in Alberta.
Ouïvia Field + Ouïvia Office · Under active development
Illustrative record · No real worker information
Designed around the day-to-day work of hearing-test companies, from the testing booth to the office. Native Windows Field and Office development prototypes exist. Calendar-led appointments and automatic authenticated synchronization are planned capabilities, not available production features.
The planned working day starts with an employer appointment calendar, opens worksite details and roster, then moves into two-booth testing. The development prototype already supports independent fictional worker forms and local draft storage.
Office manages employer appointments, provider records and reporting. Windows Office development builds include scheduling and assignment-package foundations; automatic authenticated Field-to-Office delivery remains to be built.
A worker’s audiometric history should continue across employers and testing providers. Who can see it, and when, must follow defined authorization and privacy rules.
We’re designing one persistent identity across employers and testing providers, with each test retaining its original context.
Our intended model gives a verified worker ongoing access to their history. An authorized technician can consult relevant cross-provider history during an active employer appointment; that temporary access ends when the appointment is completed. Providers retain their own tests and employers receive only permitted records. Privacy validation remains essential.
We created CADS, the Canadian Audiometric Data Standard. As its author and steward, Audiometrics Canada is building Field and Office to put it into practice.
Audiometrics Canada created CADS, the Canadian Audiometric Data Standard: an open data specification for structuring, exchanging, and connecting occupational hearing records across employers, testing providers, and provinces.
CADS is our standard. Field and Office are how we’re putting it to work.
Explore CADS documentation →Defined records for workers, tests, questionnaires, providers, technicians, and equipment—designed for consistent capture and exchange.
A national data foundation with versioned provincial profiles, so the context used for a test stays traceable as requirements evolve.
We’re evolving CADS around persistent worker identity, purpose-limited authorized history access, and clear provenance across providers and employers.
Canada already has established standards: CSA Z107.6 addresses workplace audiometric testing; CSA Z1007 addresses hearing loss prevention program management; and ASA/ANSI S3.6 specifies audiometers. CADS is intended to complement that work through a consistent data model and exchange format, with worker continuity and authorized access. It does not replace those standards or provincial requirements.
Other developers and organizations can implement CADS. Our commercial system is being developed to implement the specification. CADS remains a draft, not a designated National Standard of Canada; no CSA/ANSI endorsement, national adoption, or completed product conformance is claimed.

Field and Office belong together. The subscription includes both, with unlimited staff accounts and a fee for each new completed test accepted into the database.
Planned introductory rate: $99/month + $0.75/test for the first 12 months, with structured feedback.
Availability will be announced here. The commercial service is not open for registration yet.
Or $1,490/year for the subscription

Not yet. The commercial platform is in development, with Alberta as the first market. Pricing shown here is the planned launch structure. Registration and customer portal access will be announced when available.
Full offline testing is a launch requirement. The intended workflow provides offline appointments and authorized worker histories, saves tests locally and automatically synchronizes on reconnection. Two-booth local testing works in prototypes; authenticated sync and immediate history-access cutoff still require implementation and security testing.
Ouïvia is designed around a continuous worker record. During an authorized employer appointment, technicians may access relevant history across providers; completing the appointment ends that temporary access, even offline. Providers retain only their attributed tests; employer access is separately restricted. Identity verification and lawful disclosure controls are still being designed.
Our goal is ongoing verified worker access to their available audiometric history. The worker access portal is not built yet. For current records, workers should contact their employer or testing provider using applicable privacy-law access processes. This website has no worker lookup or health-record submission form.
Audiometrics Canada created and maintains CADS, the Canadian Audiometric Data Standard. It is an open draft specification that other systems can implement. Aud-Can is developing Field and Office as its commercial implementation. Provincial partnerships and nationwide adoption remain future goals.
No provincial adoption or partnership is being claimed. We intend to work toward provincial partnerships over time. The initial product is being developed for independent hearing-test companies.
Calls for pilot participation, feedback, and collaboration will appear in our development journal, with contact details when enquiries open.
