Sailfishboy,,
I became SSD 6 years ago after my TL surgery,, I adjusted to it quite well actually. It does not greatly affect my daily life except for the lack of directional hearing. That is the most bothersome in that it is aggravating when my husband calls to me and, if he's out of the room , I can't tell where he is,,, however, if I had poor hearing,, I probably couldn't either... also, it can be a hazard when driving or crossing the street ( I.e. Emergency vehicle approaching and you can't tell from which direction immediately ) etc,,, however,, you learn to be more cautious driving and crossing the street,,, you adjust well.
Is it ideal?? No it's not,,, is it " a big thing" ,, not for me,, now in full disclosure,,, I did get a Cochlear BAHA implanted after 3 years just to see if I could get some hearing back. I do love it since I recently upgraded to the 5 power processor,,, but I was not happy with my original processor and did not wear it all day , every day,,,, now I wear it most days. If I am at home I still don't wear it though as SSD is just not that big a deal to me,,,,
As far as not being able " to filter out background noise",, you are completely deaf in that ear so you can't filter out anything,,,, i have tinnitus still on that side so it "seems" like I have noise over there but it's not hearing,,,,,
Some folks are more troubled by SSD than others,,, but for me,, it's not a big deal.
One complication I have heard of from RS surgery is painful muscles in the neck due to them being cut to access the tumor,,, but I don't have first hand knowledge of it,,, may just be something to ask your Dr about.
Good luck with your decision,,, it's tough,,, peace,,
