Trial summary

Cochlear implants help individuals with hearing loss by delivering electrical signals directly to the auditory nerve, bypassing damaged parts of the ear. While they significantly improve speech perception in quiet environments and over the telephone, challenges remain in noisy environments due to interference from… Read more about this study

About this study

Official title: Investigating New Front-end Features in the SONNET 3

Cochlear implants help individuals with hearing loss by delivering electrical signals directly to the auditory nerve, bypassing damaged parts of the ear. While they significantly improve speech perception in quiet environments and over the telephone, challenges remain in noisy environments due to interference from background noise. To address this, advancements in signal-processing strategies, microphone technology, and noise-reduction algorithms have been introduced.

The focus of the study is on two new front-end features:

  • Focused Beamformer - Enhances directional hearing.
  • AI Mode Medium - Utilizes the adaptive intelligence for optimized sound processing.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Testing new front-end featuresOther

    New front-end features (i,e, the Focused Beamformer which nhances directional hearing and the AI Mode Medium (utilizes adaptive intelligence for optimized sound processing) will be compared to the approved beamformer and AI mode) in a within subject design. Subjects will be fitted with a MED-EL SONNET 3 audio processor.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Oldenburg Sentence Test in noise (S0 N±135)

    Speech perception in noise measured in dB SNR (the new Focused beamformer and the Omnidirectional setting are tested)

    Measured: immediately after the intervention

Secondary outcomes (2)
  1. Oldenburg Sentence Test in noise (S0 N±135)

    Speech perception in noise measured in dB SNR (the new Focused beamformer and the Natural beamformer are tested)

    Measured: immediately after the intervention

  2. Oldenburg Sentence Test in noise (S0 N±135)

    Speech perception in noise measured in dB SNR (theAI-Medium and the AI-Mild mode are tested)

    Measured: immediately after the intervention

Questions about this trial

What is this clinical trial studying?

A study testing Testing new front-end features in people with Cochlear Implant Users, run by MED-EL Elektromedizinische Geräte GmbH at 2 sites in Austria.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 12 Jun 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Austria. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Oldenburg Sentence Test in noise (S0 N±135) (time frame: immediately after the intervention). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 Jun 2026.
