Is it normal to hate disgusting eating noises people make?

Is it normal that I cannot tolerate the disgusting eating noises people make when they chew their food with their mouth open, it's so damn disgusting!!!!! My parents do it and it drives me crazy.... it's when they keep their damn mouth open and it's like this sloppy disbursing disgusting chewing noise and also when they have a soup or some instant or even a cup of tea, they make this disgusting slurping sound!!!!! I hate it, I don't do either one and always eat with my mouth closed, it's seriously disgusting and I CANNOT TOLERATE IT!!! Makes me so angry!!!!!!! Anyone else go through the same????
