Hi Seeker! Wee little foam earplugs? You didn't mention those so I'm figuring you don't like them. It occurs to me that maybe some people don't like them because they're too effective. Myself I like to fall asleep to a radio that's low enough that I can't pick out speech. Usually late night CBC radio. Mostly news...no music. The unintelligible calm voices are like white noise and it's somehow comforting. Ok when alone...no-one else likes it...heh.
As far as being awake and trying to concentrate to sounds? Sounds are just ONE thing that distracts me. Hell everything and anything distracts me when I'm awake. perhaps I should try the radio white noise thing while I'm doing something that requires focus.
Egad! You've given me an idea!!!

I shall experiment with that Seeker! Wow imagine...Canadian dolt discovers way to reduce racing thoughts in ADD patients...small earplug produces low level 'white noise' and reduces brains proclivity to etc., etc., blah, etc....
haha...well I'm going to experiment just the same. Record some stuff like I mentioned or something similar perhaps and have it running on my ipod while i read for example. Or during some normally toilsome task that requires my focus. Odd thing...surely it's already been looked at long ago and found to be negligible in effect. oh well...worth it to amuse myself!
...*yawn* bedtime for me....now where's my radio station??? 'night Seeker!
