About this trial

This is an interventional treatment trial for Hearing Loss

Eligibility Criteria

18 Years - 99 Years (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • Female and male adults between 18 and 99 years
  • German-speaking
  • Symmetric, mild to severe, ski-slope hearing loss
  • Binaural hearing aid user without frequency lowering
  • Informed Consent as documented by signature

Exclusion Criteria:

  • Have taken part in a study at Phonak within 4 months prior to the first session
  • People with mental-health problems

Arms of the Study

Arm 1

Arm Type

Experimental

Arm Label

Compressive signal processing algorithm

Arm Description

Participants compare music signals with preprocessing to the same music signals without compressive preprocessing.

Outcomes

Primary Outcome Measures

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.

Secondary Outcome Measures

Performance in music discrimination tests
Participants perform an adaptive music discrimination test in which their discrimination thresholds are measured.

5. Study Description

Brief 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. The purpose of this study is to improve music compression for hearing impaired people.
