Had it most my life and have got so used to it
I rarely notice it anymore,
unless feeling unwell or stressed...

I suppose it helps that I spend most of my waking hours
surrounded by noisy computer fans that mask the problematic frequencies,
or distracting TV and music.

A bigger problem for me is congestion and pressure in my sinuses
which cause significant fluctuations in hearing 'loss'

During the course of a day i can go from full clear hearing
to dull and muffled 'under water'...
and back again...
Completely unpredictable.
