Hi, I have several sounds in both ears combined - the usual Morse Code;tinkling bells, etc. But I also have an usual case with my right ear. The ear hums - getting louder if exposed to loud noise, etc, before returning to its base level. But if I stick my finger into that ear then I can no longer hear the hum. If I wiggle my finger in that ear before pulling it out then the ear will be silent for several seconds, before the humming returns even louder - before returning to its base line level 10 minutes or so later. The humming is only noticeable at very quiet times - mainly at night. But it is quite easy to mask out if I turn the extractor fan on or just stick my head out of the window. I would love to know if anybody else has had (or has) a similar problem.
