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 Results may not be published yet.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.

Summary

This study explores how the brain generates predictions when listening to natural sounds like speech and music. Researchers will use EEG to record brain activity while participants listen to audio and rate their pleasure and comprehension. The study includes people with normal hearing and those with hearing loss, from different cultural backgrounds, to see how these factors affect brain responses.

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
This research could improve our understanding of how the brain processes speech and music, potentially informing future hearing aids or therapies.
What could go wrong
This is an observational study, so it won't directly test a treatment. Results may not apply to all people or real-world listening situations.

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