When I write that I begin to hear something, I mean that I perceive this as a sound, not “feel” them as something like vertigo. I feel a lot of sounds this way.
It is not that I hear these sounds for the first time in my life. Most of them I have heard using hearing aids before, if they were loud enough.
New sounds: yesterday I have listened implant-only to half of the melodies from my cell phone. Some of them I have heard, some I have felt. Obviously I perceive the frequencies selectively. I think that the range is widening slowly. As a practise, I am listening to the radio at home.
