Study of Quality Perception on Music in New Cochlear Implanted Subjects Using or Not a Fine Structure Strategy

Main objective: Show the superiority of Fine Structure (FS4) strategy compared to Continuous Interleaved Sampling (HDCIS) strategy on the qualitative preference for the listening of musical pieces. Secondary objectives * Show the superiority of FS4 strategy compared to the HDCIS strategy on the perception of musical elements (contour test). * Analyze the link between the results of musical perception tests and the subjective preference of musical listening. * Show the non inferiority of FS4 strategy compared to the HDCIS strategy on the perception of speech elements. * Analyze the link between the results of musical perception tests and the results of the perception of speech elements. * Analyze the qualitative multidimensional perception with HDCIS and FS4
