Noise

I feel so much better knowing that I’m not the only one suffering with something like this. But their is something else I have an issue with that I haven’t seen on here, I have an issue with hearing certain sounds or shall I say letters. For example the word snake the ‘sss’ irritates me so I can’t watch a lot of tv or can’t speak to certain people if they pronounce their letter ‘s’ strongly! Also i can’t deal with it when I hear someone else Tv and all I can hear is that sound where it’s like someone is just hissing. 

I don’t know if this makes any sense to any one? 
I finally went to the doctors a year ago and I am seeing audiologist they haven’t done much yet, just lots of testing. I’m wondering if their is anyone one that has this particular issue. I do wear ear buds but their not strong enough to block out all sound.
