I am partially hearing impaired, I'm half-deaf.
My right ear is only capable of about 10% - 20% of normal hearing capacity.
But because I've been like this since I was a little kid, I grew up with this lower level of hearing. I never experienced any "normal hearing level" before, so I have no standard of which to compare my current hearing to (ignorance is bliss...?).
Those who lose part of their hearing at some point of their life often comment on how hard it is because they have to concentrate and listen much more carefully to hear what they used to be able to hear. I however didn't go through this phase because I was always half-deaf, meaning there wasn't a learning-curve for me to adjust to an "inferior" level of hearing.
Overall it doesn't bother me that much. I guess I'm one of the lucky ones in regards to hearing loss.
