About this study

Communication on telephone is challenging for people with hearing loss. For hearing aid users, for instance, the inventions for improving speech intelligibility on the phone range from an integrated tele coil and individual hearing programs to specially designed phone devices. No formal studies involving these devices have been carried out with CI users.

Thus, this comparative study includes hearing aid as well as CI and bimodal users to evaluate different hearing solutions for communication on telephone in terms of intelligibility and ease of use.

Read the detailed description

Communication on telephone is challenging for people with hearing loss, due to a number of factors:

  • The lack of visual cues (lip-reading),
  • The lack of binaural abilities,
  • The presence of (loud) background noise in a variety of listening situations,
  • A modified speech signal due to reduced frequency bandwidth and
  • Difficulties coupling the phone to the CI. For hearing aid users, for instance, the inventions for improving speech intelligibility on the phone range from an integrated tele coil and individual hearing programs to specially designed phone devices.

No formal studies involving these devices have been carried out with CI users.

Thus, this comparative study includes hearing aid as well as CI and bimodal users to evaluate the different hearing solutions for communication on telephone in terms of intelligibility and ease of use:

  • Phonak DECT - cordless telephone for HA-, CI- users and bimodal users
  • Phonak EasyCall - accessories for Bluetooth capable mobile telephones for HA-, CI- and bimodal users
  • Phonak DuoPhone - streaming function, which provides the speech signal to both ears

What is being measured

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

  1. speech reception threshold (SRT) assessment with audiological measures

    differences in speech reception threshold (SRT) on the phone in the presence of background noise between the Phonak DECT phone and a standard phone will be assessed with audiological measures.

    Measured: 6 months

Secondary outcomes (1)
  1. Subjective ratings assessment with scaling

    • differences in preference ratings in the presence of background noise between a standard phone, a standard phone + DuoPhone algorithm, the DECT-telephone
    • differences in preference ratings in the presence of background noise between a standard mobile phone, a standard mobile phone + DuoPhone algorithm and a standard mobile phone + EasyCall accessory

    Measured: 6 months

Questions about this trial

What is this clinical trial studying?

A study testing standard telephone setting, DECT and EasyCall in people with Hearing Loss, Binaural and Hearing Loss, Monaural, run by Advanced Bionics AG at 1 site in Switzerland.

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 9 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: finished, as of the sponsor's last update on 7 Sep 2017. 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 reception threshold (SRT) assessment with audiological measures (time frame: 6 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03036410, which also lists 5 linked publications.

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 Sep 2017.
