Additional Study Information: Do you have a Cochlear Implant for more than 6 months? Do you wish music could sound better? You may be qualified to participate in our Music Enjoyment study. We are seeking volunteers who have had a Cochlear Implant for at least 6 months, are 18+ years old, and who speak English, to listen to clips of chart topping songs in 5 genres and to modify parameters of the music on our new software in order to make the music sound better. It will take 30-45 minutes of your time, and you can participate in our offices at Columbia or at home. If you complete this study in office, you will be compensated $40 for your time.
