I was sitting at church during "chat time" and realized that I can hear pretty much every single word of every conversation but I can't focus on just one so its just a jumble of words that don't go together. I have trouble understanding speech which I've always just attributed to hearing loss, but I don't really think that's it. I think my ability to filter out other sounds is getting worse as I age. When I'm talking with someone, mostly the speech is just fragments and I mentally try different words to see if its a possibility. If nothing makes sense then I have to ask for clarification.
For a while, my daughter was using something called "therapuetic listening". It was classical music that was modified to have all the low frequencies shut off at random intervals. It did seems to help her with motor skills (she was suddenly able to put on her socks while listening to it). One day she stuck the headphones on me. It just made my mind turn to jello. I couldn't even speak to tell her to take them off and I couldn't organize my thoughts enough to figure out how to get them off myself. Tres weird.
