For me (ADD) it help a lot with a couple of simple music ear plugs. It might sound a bit weird, but the lower volume helps me pick out voices much easier. Also concerts started sounding like music instead of mostly ... noise.

Has been like this forever and have never had any (other) problems with my hearing.

Can't agree with this more! Seriously, if you're a fan of live music, grab a pair and just try it at the next concert you go to.

Its a signal/noise attenuation, you'll hear _more_ detail, not less.

A pair like these are what I'd consider 'high end':

But I've always got a cheap set from the pharmacy in my pocket or the car somewhere. Something like this is perfect:
