Optimization of Music Compression

Not Applicable

Completed

• Conditions: Hearing Loss
• Interventions: Other: Audio signal processing (applied offline before playback)

• Registration Number: NCT02373228
• Lead Sponsor: Phonak AG, Switzerland

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.

Arm && Interventions

Group	Intervention	Description
Compressive signal processing algorithm	Audio signal processing (applied offline before playback)	Participants compare music signals with preprocessing to the same music signals without compressive preprocessing.

Primary Outcome Measures

Name	Time	Method
Benefit of signal processing for music perception	3 months	Participants rate the enjoyment of music in 4 separate sessions, spread over an anticipated time frame of 3 months.

Secondary Outcome Measures

Name	Time	Method
Performance in music discrimination tests	3 months	Participants perform an adaptive music discrimination test in which their discrimination thresholds are measured.
