What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting This study
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study looks at how temporary noise exposure at levels allowed by law (around 85 dB) affects hearing and thinking in 40 healthy adults aged 18-35. Participants will be exposed to different noise patterns, including with rest breaks, to see if breaks help reduce auditory fatigue. The goal is to better understand noise-related fatigue and improve safety recommendations for workers.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this study could lead to better workplace guidelines to protect hearing and reduce errors from noise-induced fatigue.
What could go wrong
This is a small, early-stage study in healthy volunteers, not patients. Results may not apply to real-world work settings or people with hearing issues.

This is an AI summary of the original study and may miss details. Read our disclaimer.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 40 people

The number the study aims to enrol. It can still change while the study runs.

Expected to start

May 2026

An estimate. Start dates often move.

Expected to finish

Feb 2028

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Ages

Healthy volunteers

Accepted

You do not need to have the condition being studied to take part.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Healthy subjects aged between 18 and 35 * With normal pure-tone audiometry data (air and bone conductions) on both ears: hearing thresholds ≤20 dB HL for each frequency tested - 125, 250, 500, 1000, 2000, 3000, 4000, 6000 and 8000 Hz * With normal Speech-in-noise test (the speech reception threshold (SRT) at which 50% recognition of the speech stimuli presented is achieved must be 3 dB higher than the standard test value established in subjects with normal hearing) * Without history of excessive noise exposure (1-MINUTE NOISE SCREEN ≤4) Exclusion Criteria: * History of sudden deafness or tinnitus lasting more than 48 hours * Conditions likely to affect hearing (tumours of the ear or base of the skull, etc.) * History of unresolved chronic otitis * Work in a noisy environment requiring workplace soundproofing or the use of personal protective equipment * Migraine with or without aura or tension-type headaches (International Headache Society (IHS) classification) * Pregnant or breastfeeding women or women of childbearing age not using contraception * Participation in another interventional clinical trial * A person whose physical and/or psychological health is severely impaired * Individuals deprived of their legal capacity, or under guardianship or trusteeship * Persons deprived of liberty (by judicial or administrative decision) * Not affiliated to a French social security system or not a beneficiary of this system * Absence written informed consent to participate in the study
