About this study

Sonova Hearing Systems pass through different development and study stages. At an early stage, feasibility studies are conducted to investigate new algorithms, features and functions in an isolated manner. If the benefit is proven, their performance is then investigated regarding interdependency between all available algorithms, features and functions running in parallel in a hearing aid (pivotal/pre-validation studies) and, as a result, they get optimized. Afterwards, and prior to product launch, the Sonova Hearing Systems undergo a final quality control in terms of clinical trials. This is a confirmatory study, investigating benefits of a modified hearing aid loudspeaker. This will be a clinical investigation which will be conducted mono centric at National Acoustic Laboratories a well known institution with exceptional experience (Australia).

Read the detailed description

In this study a comparison with two Phonak Receiver in Canal (RIC) devices is done. The experimental device with a modified hearing aid loudspeaker concept and the active comparator with the existing technology will be compared regarding speech intelligibility, listening effort and sound quality in speech in noise, quiet situations for people with mild to moderate hearing losses.

What is being measured

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

  1. Evaluation of speech intelligibility and sound quality for different loudspeaker

    The Primary Outcome measure of this study is the comparison of the standard hearing aid loudspeaker with the modified one in regard to speech intelligibility in a noisy environment and sound quality in a quiet situation.

    The speech intelligibility will be measured using a speech test in dB SRT and the sound quality will be assessed by subjective rating, using percentage of satisfaction from "very satisfied (100)" to "very unsatisfied (0)".

    Measured: 2 weeks

Secondary outcomes (3)
  1. Evaluation of listening effort for different loudspeaker.

    The Secondary Outcome measure of this study is the comparison of the standard hearing aid loudspeaker with the modified one in regard to listening effort in a noisy environment.

    The listening effort of speech will be assessed by subjective rating, within 13 steps, from "not effortful at all" to "only noise".

    Measured: 2 weeks

  2. Evaluation of sound quality of own voice for different loudspeaker.

    The Secondary Outcome measure of this study is the comparison of the standard hearing aid loudspeaker with the modified one in regard to sound quality in quiet.

    The sound quality of own voice will be assessed by subjective rating, using percentage of satisfaction from "very satisfied (100)" to "very unsatisfied (0)".

    Measured: 2 weeks

  3. Evaluation of sound quality of streamed signals for different loudspeaker

    The Secondary Outcome measure of this study is the comparison of the standard hearing aid loudspeaker with the modified one in regard to sound quality of a streamed signal in quiet and noise..

    The sound quality of the streamed signal will be assessed by subjective rating, using percentage of satisfaction from "very satisfied (100)" to "very unsatisfied (0)".

    Measured: 2 weeks

Questions about this trial

What is this clinical trial studying?

A study testing New hearing aid loudspeaker and Standard hearing aid loudspeaker in people with Hearing Loss, run by Sonova AG at 1 site in Australia.

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 7 inclusion and 5 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 28 Mar 2023. 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 Australia. 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?

Evaluation of speech intelligibility and sound quality for different loudspeaker (time frame: 2 weeks). 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 28 Mar 2023.
