Optimization of Music Compression (OMC)

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT02373228
Recruitment Status : Completed
First Posted : February 26, 2015

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 Intervention/treatment
Experimental: Compressive signal processing algorithm
Participants compare music signals with preprocessing to the same music signals without compressive preprocessing.
Other: Audio signal processing (applied offline before playback)

Primary Outcome Measures :
  1. Benefit of signal processing for music perception [ Time Frame: 3 months ]
    Participants rate the enjoyment of music in 4 separate sessions, spread over an anticipated time frame of 3 months.

Secondary Outcome Measures :
  1. Performance in music discrimination tests [ Time Frame: 3 months ]
    Participants perform an adaptive music discrimination test in which their discrimination thresholds are measured.
