I'd like to ask you a favour, if you're reading this. Can you watch the video below, and tell me what speech and music sounds like to you in the comments section below?
There are several clips of speech and music - I'm assuming that the implant I am getting will be closest to the 20 channel samples you hear on the video.
This is an approximation of the sound of a cochlear implant using sound editing software.
Read the comments on the video here. A couple of CI users there who have said that they can hear a marked difference between 'normal speech' and that video!
What you may find is that if you listen to the video more than once, the speech and music becomes clearer each time. This is the brain 'learning' the sounds for you. This article explains how that works in more detail.

I look forward to your thoughts.
