I'm suffering from tinnitus. In my case, this is a constant, high-pitched whine. The volume is insignificant when I'm relaxed in quiet surroundings, but stress and loud noise can instantly increase the volume to an intolerable level. It's a torture one can't escape from.
You can probably imagine that holding a crying infant in my arms (to get him to sleep) isn't helpful for my ears. I have begun to use foam-rubber ear plugs at home but they aren't very comfortable. High-quality wax ear plugs are exceedingly efficient; they make me practically deaf which isn't helpful either, in this situation (but very good with power tools).
I'd like to hear suggestions or experiences about what works in this situation—besides handing the baby over to my wife. My goal is to reduce or remove the higher frequencies but not completely disable my hearing.
