Occupational Deafness: Mandatory Follow-Up Audiometry to Confirm Origin

Imagine: you have been working for eight years in a factory in Ramonville-Saint-Agne, where machines emit constant noise. One day, you consult a doctor who diagnoses deafness. You report the occupational disease. But a few months after leaving the company, the employer contests: he demands a new audiometry to prove that your deafness is indeed irreversible and work-related. What to do? This 1984 decision of the Court of Cassation precisely settles this point: without this check within the deadlines, the employer can refuse coverage. A lesson for all employees exposed to noise, and for employers who must ensure these checks are carried out.

The Facts: A Story Like Many Others

Mr. X, a worker in a metallurgy company in Pamiers, worked from 1 January 1970 to 31 January 1978 in a workshop where noise levels exceeded regulatory thresholds. In 1977, he felt a hearing loss and consulted an ENT specialist. The diagnosis: bilateral deafness. He reported the occupational disease to the Primary Health Insurance Fund (CPAM).

The CPAM recognised the occupational origin and the employer contested. Why? Because, according to the regulations in force at the time, deafness declared before the end of noise exposure must be confirmed by an audiometry carried out between six months and one year after the cessation of exposure. This measure checks the irreversible nature of the condition (i.e., it does not heal spontaneously).

However, in this case, no follow-up audiometry was carried out within this period. The employer brought the case before the Social Security Tribunal (TASS) to have the recognition annulled. The TASS ruled in favour of the employer, and Mr. X appealed to the Court of Cassation. The Court of Cassation confirmed: without this check, the proof of occupational origin is not established. The employer is entitled to rely on this failure.

The Reasoning of the Court – Analysed

The Court of Cassation relies on the provisions of the Social Security Code relating to occupational diseases, and more specifically on Table No. 42 (occupational deafness). This table requires that deafness be established by pure tone and speech audiometry, and that the diagnosis be confirmed by a new audiometry within six months to one year after the cessation of exposure to the risk. This requirement aims to rule out non-occupational causes (e.g., age-related hearing loss or infection).

The Court recalls that compliance with this formality is a condition for the presumption of occupational origin (the presumption is the legal mechanism that allows a disease to be considered work-related unless proven otherwise). In the absence of this follow-up audiometry, the presumption cannot apply, and the employer may legitimately contest.

The judgment does not constitute a reversal of precedent (a radical change in the interpretation of the law), but a confirmation of the strictness of the medical conditions. It shows that judges are committed to solid scientific evidence to avoid abuses. Mr. X's arguments — for example, that the deafness was already diagnosed before the end of exposure — were not accepted.

What This Means for You – in Practice

For employees exposed to noise: if you report deafness before leaving your post, you must absolutely have a follow-up audiometry carried out within six to twelve months of your departure. Without it, your employer can refuse recognition of the occupational disease, and you will lose benefits (pension, medical coverage).

For employers: you have an interest in requiring this follow-up audiometry. If the employee does not have it done, you can contest the declaration. A concrete example: in Pamiers, a 50-employee SME saved €120,000 in additional contributions by contesting an unconfirmed deafness claim.

For property professionals (landlords, property managers): even if workplace noise is the issue, remind your tenants or co-owners who are exposed (e.g., noisy workshops) that they must respect these deadlines.

Four Tips to Avoid This Type of Dispute

• Carry out the follow-up audiometry within the deadlines: as soon as you leave your noisy post, book an appointment with an ENT specialist for an audiometry between 6 months and 1 year after. Note the date in your diary.
• Keep all medical documents: keep the initial audiometry, the follow-up audiometry, and reports. In case of dispute, these are your evidence.
• Report the disease without delay: even if the follow-up audiometry has not yet been done, report it as soon as the initial diagnosis is made. The CPAM will guide you on the next steps.
• Inform your occupational physician: he can help you organise follow-up and comply with legal deadlines.

Further Reading: Related Case Law and Developments

Before this judgment, some courts of appeal considered that the follow-up audiometry was merely a recommendation. The Court of Cassation put an end to this uncertainty in 1984. Since then, case law has been consistent: without this check, no presumption of occupational origin. A later decision (Civ. 2e, 12 February 1998, No. 96-15.234) even extended the obligation to cases where deafness is declared after cessation of exposure, but with a stricter deadline.

The trend of the courts is therefore towards stricter requirements for medical evidence. In the future, employers may be tempted to systematically contest in the absence of a check. Employees must therefore be particularly vigilant.
