Trial summary

Claims evidence is required for a new Wind Noise Canceller (WNC) algorithm. Wind noise is not sound in the classic sense, as it does not correspond to pressure waves moving through the air. However, because the microphone membranes are deflected by the wind noise, the microphones translates them into a sound signal. Read more about this study

About this study

Claims evidence is required for a new Wind Noise Canceller (WNC) algorithm.

Wind noise is not sound in the classic sense, as it does not correspond to pressure waves moving through the air. However, because the microphone membranes are deflected by the wind noise, the microphones translates them into a sound signal. Since the pressure fluctuations are small in size, this wind noise signal is uncorrelated between the two HI microphones (correlation decreases with increasing microphone distance), creating bothersome sounds at low and very low frequencies. Historically, wind noise cancellers have been applied to make wind noise less bothersome. However, target signal (i.e. speech) sound fidelity can become compromised as a biproduct. Therefore, an updated wind noise canceller has been proposed to improve wind noise attenuation and target signal fidelity compared to the previous iteration. Informal exploratory testing by normal hearing Sonova employees have identified the new wind noise canceller iteration to improve sound quality ratings with some dependencies on (1) wind speed, (2) wind angle and (3) target signal. Therefore, this study will aim to produce sound quality data showing a benefit for the new wind noise canceller compared to the older version for the purpose of claim substantiation.

What participants receive

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

  • New wind noise cancellerDevice

    Updated wind noise canceller intended to improve wind noise attenuation and target signal fidelity compared to its predecessor.

  • Old wind noise cancellerDevice

    Older version of the wind noise canceller

Study groups in NCT07543770
Study groupRoleWhat they receive
Participant groupExperimentalParticipants will listen to recorded scenes of target signals (speech, environmental sounds) in a wind tunnel, in which wind speed and incidence angle will be varied, recorded using the old and new versions of the wind noise canceller. Condition order is randomized between participants and masked from participants and experimenters.

What is being measured

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

  1. Overall preference sound quality attribute

    Participants will complete an A-B paired-comparison listening task to assess subjective preference for overall preference between two hearing aid conditions. During testing, participants will listen to short audio recordings that vary in target signal, wind speed, and wind incidence angle. For each trial, participants will indicate which of the two recordings (A or B) is preferred overall. The outcome measure will be the proportion of "A preferred" versus "B preferred" responses aggregated across all trials and participants. Binary preference data will be analyzed using inferential statistics.

    Measured: During a single 2-hour onsite study session

Secondary outcomes (4)
  1. Speech clarity sound quality attribute

    Participants will complete an A-B paired-comparison listening task to assess subjective preference for speech clarity between two hearing aid conditions. During testing, participants will listen to short audio recordings that vary in target signal, wind speed, and wind incidence angle. For each trial, participants will indicate which of the two recordings (A or B) is preferred in terms of speech clarity. The outcome measure will be the proportion of "A preferred" versus "B preferred" responses aggregated across all trials and participants. Binary preference data will be analyzed using inferential statistics.

    Measured: During a single 2-hour onsite study session

  2. Listening comfort sound quality attribute

    Participants will complete an A-B paired-comparison listening task to assess subjective preference for listening comfort between two hearing aid conditions. During testing, participants will listen to short audio recordings that vary in target signal, wind speed, and wind incidence angle. For each trial, participants will indicate which of the two recordings (A or B) is preferred in terms of listening comfort. The outcome measure will be the proportion of "A preferred" versus "B preferred" responses aggregated across all trials and participants. Binary preference data will be analyzed using inferential statistics.

    Measured: During a single 2-hour onsite study session

  3. Listening effort sound quality attribute

    Participants will complete an A-B paired-comparison listening task to assess subjective preference for listening effort between two hearing aid conditions. During testing, participants will listen to short audio recordings that vary in target signal, wind speed, and wind incidence angle. For each trial, participants will indicate which of the two recordings (A or B) is preferred in terms of listening effort. The outcome measure will be the proportion of "A preferred" versus "B preferred" responses aggregated across all trials and participants. Binary preference data will be analyzed using inferential statistics.

    Measured: During a single 2-hour onsite study session

  4. Naturalness sound quality attribute

    Participants will complete an A-B paired-comparison listening task to assess subjective preference for naturalness between two hearing aid conditions. During testing, participants will listen to short audio recordings that vary in target signal, wind speed, and wind incidence angle. For each trial, participants will indicate which of the two recordings (A or B) is preferred in terms of naturalness. The outcome measure will be the proportion of "A preferred" versus "B preferred" responses aggregated across all trials and participants. Binary preference data will be analyzed using inferential statistics.

    Measured: During a single 2-hour onsite study session

Questions about this trial

What is this clinical trial studying?

A study testing New wind noise canceller and Old wind noise canceller in people with Hearing Loss, run by Jonathan Vaisberg at 1 site in Canada.

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 3 inclusion and 2 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: opening soon, as of the sponsor's last update on 22 Apr 2026. 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 Canada. 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?

This study is still under way. Results are not available in the source record yet.

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

Contact Jonathan M Vaisberg, PhD (905-745-6785, jonathan.vaisberg@sonova.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Overall preference sound quality attribute (time frame: During a single 2-hour onsite study session). 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?
