Now and then I notice a very brief, complete silence in my ear and then the T starts up again. That brief millisecond is very quiet. It makes me wonder how shocked we all would be if we really got rid of our T sounds 100%? I bet there are sounds/tones/hisses/rumbles we don't even know we have habituated to and that we would all be shocked at how many noises were in our heads this whole time that we weren't even aware of.
