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
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 This study
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 looked at whether a person's working memory should influence how hearing aids are set. Researchers tested 42 adults with hearing loss in a lab, adjusting two features: directional microphones and compression. Participants listened to sentences in noise from different directions to see which settings helped them understand speech best. The goal is to make hearing aids work better in real-world, noisy situations by tailoring them to each person's cognitive strengths.

What this could mean

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

Active substance
Hearing aid with adjustable directional microphones and compression settings
What this could lead to
If successful, this could lead to personalized hearing aid programming based on cognitive abilities, improving speech understanding in noisy environments.
What could go wrong
This is a small, completed study with 42 participants, so results may not apply to everyone. It only tested immediate effects in a lab, not long-term real-world use.
