About this study

Official title: A Comparative Clinical Investigation of Two Hearing Instrument Digital Signal Processing Strategies and Their Effect on Speech Understanding

The purpose of this study is to show that the performance of the new digital signal processing system is better than the system used in the currently CE marked devices. Speech in narrowband noise and acceptable levels of noise should be improved with the new system, and speech understanding overall should not be negatively affected. There should be no artefacts or unwanted noises caused by the new system.

Read the detailed description

This is a controlled, double-blinded, comparative clinical evaluation conducted monocentric at the premised of Bernafon AG in Bern, Switzerland.

For this study, Bernafon AG will carry out testing with participants with hearing loss to validate the performance of a new digital signal processing (DSP). System testing of the DSP shows an improved signal, yet it must be tested with humans to be sure of an improvement in real-life situations. The current study will compare the new DSP to the one that is used in the Bernafon hearing aids that are CE- marked and currently available on the market. The goal is to determine whether the new DSP is better in real-life situations than the current system.

Primary Endpoint: The primary objective is to assess the new DSP system with various hearing losses and levels of amplification. Speech testing will be used to analyse the speech perception of participants.

Secondary Endpoint: The secondary objective is to verify the overall performance of the new device. Acceptable noise levels will be measured as well as further speech testing. Questionnaires will be used to measure subjective responses to the performance.

Other Endpoints: The subjective performance of an optimized fitting versus a standard fitting and the acceptance of new domes will be measured with questionnaires.

Safety Endpoint: The study aims to identify any new risk factors and to ensure the safety of the device with the newly implemented DSP system before releasing it to the market.

What is being measured

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

  1. Speech perception with narrowband noise

    Speech perception is tested using a standardized speech test that requires subjects to repeat sentences presented among narrowband background noise. The test is adaptive with the background noise getting louder or softer so that the subject answers 50% correct. The scores are measured in dB SNR (signal-to-noise ratio) and a lower score is better. The lowest possible score is -15 dB SNR and the highest is +20 dB SNR. It is measured in the unaided condition.

    Measured: Week 1

  2. Speech perception with narrowband noise

    Speech perception is tested using a standardized speech test that requires subjects to repeat sentences presented among narrowband background noise. The test is adaptive with the background noise getting louder or softer so that the subject answers 50% correct. The scores are measured in dB SNR (signal-to-noise ratio) and a lower score is better. The lowest possible score is -15 dB SNR and the highest is +20 dB SNR. It is measured in the aided condition with the new device or the current device depending on the randomization.

    Measured: Week 2

  3. Speech perception with narrowband noise

    Speech perception is tested using a standardized speech test that requires subjects to repeat sentences presented among narrowband background noise. The test is adaptive with the background noise getting louder or softer so that the subject answers 50% correct. The scores are measured in dB SNR (signal-to-noise ratio) and a lower score is better. The lowest possible score is -15 dB SNR and the highest is +20 dB SNR. It is measured in the aided condition with the new device or the current device depending on the randomization.

    Measured: Week 3

Secondary outcomes (6)
  1. Speech perception with broadband noise

    Speech perception is tested using a standardized speech test that requires subjects to repeat sentences presented among broadband background noise. The test is adaptive with the background noise getting louder or softer so that the subject answers 50% correct. The scores are measured in dB SNR (signal-to-noise ratio) and a lower score is better. The lowest possible score is -15 dB SNR and the highest is +20 dB SNR. It is measured in the unaided condition.

  4. Acceptance of noise

    Acceptance of noise is tested using a standardized noise test that requires the subjects to adjust the background noise to the maximum Levels that they can tolerate it and to the Levels at which they can understand speech. It is measured in dB SNR (signal-to-noise ratio) and a lower score is better. The lowest score possible is -25 dB SNR and the highest is +20 dB SNR. It is measured in the unaided condition.

    Measured: Week 1

The record says: finished, as of the sponsor's last update on 7 Jan 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 Switzerland. 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 with narrowband noise (time frame: Week 1). The study lists 3 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 7 Jan 2021.
