About this study

The study aims to compare two different cochlear implant sound processing strategies. All the participants will start off with a sound processing strategy called the XDP (extended performance). At the 3 month stage, half of the participants would randomly be selected and offered a sound processing strategy called the Voice Guard. Following that, the sound processing strategies will be altered and evaluated every 3 months at the 6th, 9th and 12th month of cochlear implant use.

Read the detailed description

Voice Guard and XDP are two different cochlear implant sound processing strategies. The Voice Guard sound coding strategy is adaptive in nature and can alter the output from the cochlear implant based on the levels of the listening environment. Hence, it can adapt to soft, medium or conversational and loud speech levels.The XDP on the other hand is not adaptive and cannot alter the cochlear implant output according to the levels of the listening environment.

In the study we are hypothesising that the Voice Guard sound processing strategy will perform better than the XDP strategy for soft (40 dB SPL) and loud (85 dB SPL) speech input levels. Speech perception scores will be recorded at 40, 65 and 85 dB SPL and a cross over study design has been adopted.

In addition, the efficacy of a cochlear implant sound reduction technique called Voice Track will also be evaluated. The Voice Track is designed to reduce the adverse effect of background noise on cochlear implant speech perception.

What is being measured

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

  1. Speech perception scores in quite and in noise

    Speech perception with each intervention will be measured and a score between 0 to 100% will be obtained

    Measured: 12 months

Secondary outcomes (1)
  1. Patient reported outcome measure

    Glasgow Hearing aid Benefit profile will be administered to assess patient reported benefit with each intervention

    Measured: 12 months

Questions about this trial

What is this clinical trial studying?

A study testing XDP sound processing strategy - Period 0, XDP sound processing strategy - Period 1 and VG sound processing strategy - Period 1 in people with Cochlear Implantation, run by Oticon Medical at 2 sites in United Kingdom.

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 3 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 Jan 2023. 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 United Kingdom. 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?

Speech perception scores in quite and in noise (time frame: 12 months). 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 Jan 2023.
