When I pay attention to it, my ears are filled with all kinds of whines, ringings, clickings and so forth. Is this a part of the normal aging process? When I am engaged in listening to other things, I am not aware of the sounds in my ears, but if I deliberately focus on it, my head fills with weird sounds. I've considered replicating or simulating the sounds I hear on an electronic keyboard. I wonder if this is possible.
