New strategy stimulate smaller number of channels in comparison of active channel's nu mber. The strategy is based on standard ACE strategy . The difference is the psycho-aco ustic masking model which recognize the mos t im portant compo nents from the audio signal. The study was designed as a prosp ective multi-centre clinic al study in 7 Europe an langua ge areas. 247 patients from 37 Cochlear Impla nt Centers took part into the research.
