Optimization of Music Compression
A study testing Audio signal processing (applied offline before playback) in people with Hearing Loss, run by Phonak AG, Switzerland at 1 site in Switzerland.
Trial summary
Hearing impaired persons suffer from inferior music perception with and without hearing aids. Hearing aids, however, are primarily designed to improve speech intelligibility not music enjoyment. This study investigates the potential benefit of signal processing strategies that are optimized for music. Read more about this study

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Audio signal processing (applied offline before playback)Other
| Study group | Role | What they receive |
|---|---|---|
| Compressive signal processing algorithm | Experimental | Participants compare music signals with preprocessing to the same music signals without compressive preprocessing. Receives: Other: Audio signal processing (applied offline before playback) |
What is being measured
The primary outcome is the main question the study is designed to answer.
Benefit of signal processing for music perception
Participants rate the enjoyment of music in 4 separate sessions, spread over an anticipated time frame of 3 months.
Measured: 3 months
Secondary outcomes (1)
Performance in music discrimination tests
Participants perform an adaptive music discrimination test in which their discrimination thresholds are measured.
Measured: 3 months

Questions about this trial
What is this clinical trial studying?
A study testing Audio signal processing (applied offline before playback) in people with Hearing Loss, run by Phonak AG, Switzerland 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 5 inclusion and 4 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 20 Oct 2015. 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?
Benefit of signal processing for music perception (time frame: 3 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 NCT02373228, which also lists 1 linked publication.
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 20 Oct 2015.
