What participants receive

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

  • New Sound ProcessorDevice

    The new Sound Processor is intended to be used as part of the Cochlear Baha System which uses bone conduction to transmit sounds to the cochlea. The New Sound Processor is indicated for patients with up to 55 dB sensorineural hearing loss.

What is being measured

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

  1. Hearing Performance of Speech in Noise for Unaided Hearing and the Baha 6 Max Assessed Via Adaptive Speech Test in Noise

    Using validated lists of phonetically balanced sentences. Noise is kept constant at 65 dB Sound Pressure Level (SPL) and the speech is adapted stepwise to establish the speech-to-noise ratio providing a 50% level of understanding

    Measured: Day 0, day 7 and day 14

  2. Participant Preference for the Baha 6 Max or Baha 5 SP Assessed Via Questions in the eCRF

    Measured: Day 14

Secondary outcomes (9)
  1. Descriptive Hearing Performance for the Baha 6 Max and Baha 5 SP in a Home/Normal Hearing Environment Assessed Via a Diary

    Diary completed by the participant with following topics: daily use of the sound processor (hours), change of battery, switch to their own sound processor.

    Measured: Day 7 and day 14

  2. Hearing Performance for the Baha 6 Max and Baha 5 SP Assessed Via Adaptive Speech Test in Noise

    Using validated lists of phonetically balanced sentences. Noise is kept constant at 65 dB SPL and the speech is adapted stepwise to establish the speech-to-noise ratio providing a 50% level of understanding

    Measured: Day 0 and day 7

  3. Hearing Performance for the Baha 6 Max and Baha 5 SP Assessed Via Thresholds Audiometry

    Sound-field [0.25, 0.5, 1.0, 2.0, 3.0, 4.0, 6.0, 8.0 9.0 and 10.0 kHz]

    Measured: Day 0 and day 7

  4. Hearing Performance for the Baha 6 Max and Baha 5 SP Assessed Via Speech Test in Quiet

    Using monosyllabic words presented at 65 dB SPL with scores recorded as % correct words.

    Measured: Day 0 and day 7

  5. Hearing Performance for the Baha 6 Max and Baha 5 SP Assessed Via Participant Rating

    Participant rating on a likert scale from 1-5 where 1 represents the most negative and 5 represents the most positive experience of loudness, sound quality, sound clarity, speech understanding, presence of artefacts after listening to sound clips.

    Measured: Day 14

  6. Hearing Performance for Baha 6 Max and Baha 5 SP Assessed Via Participant Rating for Internal Noise

    Participant rating Yes or No for internal noise after listening to sound clips.

    Measured: Day 14

  7. Hearing Performance for Baha 6 Max and Baha 5 SP Assessed Via Participant Rating for Listening Effort.

    Participant rating for listening effort assessed with the Borg scale. The Borg scale measures the level of effort it takes trying to hear what is said in a sound clip. The scale is from 0-10 where 0= no effort at all and 10=maximal effort.

    Measured: Day 14

  8. Hearing Performance for Baha 6 Max and Unaided Assessed Via Thresholds Audiometry

    Sound-field [0.25, 0.5, 1.0, 2.0, 3.0, 4.0, 6.0, 8.0, 9.0 and 10.0 kHz]

    Measured: Day 0, day 7 and day 14

  9. Hearing Performance for Baha 6 Max and Unaided Assessed Via Speech Test in Quiet

    Using monosyllabic words presented at 65 dB SPL with scores recorded as % correct words

    Measured: Day 0, day 7 and day 14

Questions about this trial

What is this clinical trial studying?

A study testing New Sound Processor in people with Hearing Loss, run by Cochlear at 1 site in Sweden.

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 4 inclusion and 6 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 22 Nov 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Sweden. 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?

Yes. Results are posted in the registry (first posted 22 Nov 2021). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Hearing Performance of Speech in Noise for Unaided Hearing and the Baha 6 Max Assessed Via Adaptive Speech Test in Noise (time frame: Day 0, day 7 and day 14). The study lists 2 primary outcomes in all. 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 22 Nov 2021.
