a year, you will notice that things sound the same as your brain rewires itself. i can only tell there is no bass in my music since my sound processor starts at 188 hz so i hear none of the bass freq. The high frequencies are night and day different on music , speech understanding. CI triumph that. My hearing in my left non CI ear is 80% WRS and i can tell you that they merge very effectively , i’m doing extremely well in noise and My CI is 80%, bimodal 96% bimodal noise test was 70% (Oticon dynamo and n7)
…4 years, upgraded from N7 so N8, and oticon dynamo/resound quattro to resound omnia. it is turned me into a hearing person that more than what i asked for in my CI
