He makes noise constantly

My sisters DH, who has just turned 50, is awful for this. I can't sit next to, or opposite him at the dinner table because he makes these disgusting wet sounds as he chews. He also hasn't mastered the art of consistently chewing with his mouth closed.
And then when we're just sitting around relaxing, he makes these constant "mmmm!" sounds under his breath. It really grinds my gears!

No not unreasonable. I said on another thread, men making these noises is just another form of man-spreading. It’s generally men who are making ridiculous noises with little reason and women are then told they have misphonia. I never had huge issues with noise but over the years with my ex I got driven to despair. The slurping, lip smacking, slow crunching of every bite, licking fingers clean with a ‘pop’, throat clearing, loud sneezing, dry nose blowing… I couldn’t live with it ever again. Since my kids have been going to his after we split my eldest has developed a habit of unnecessary throat clearing/hacking as well 😑.

This finished me off. I would be fucking murderous.

Some of it sounds purposeful like the stomping around but others like frequent throat clearing and snorting sounds like
common tics.

I know what you mean. It’s the sheer lack of consideration that winds me up. It doesn’t even occur to them that they should take others into account. It’s very entitled. I also could wonder around scratching, farting, burping and grunting, but I don’t.

Oh! I Know. The constant throat clearing and snorting drives me bats too. That was until I got similarly afflicted, so now I know how irritating it can be. But at least I try and do it quietly - except for sneezing which is repetitive and makes windows rattle - so I get my own back!

It could be a combination of the two. When my husband's pissing me off I feel like every sound he makes is multiplied. Having said that, as he's moved into his 40s he makes more sounds than ever before- I pointed out yesterday that he seems to grunt as he breathes these days?! You should be able to raise with him that this is bothering you but, tbh, I don't know what he can do to stop it really (my mum just laughed and told me it gets worse when they hit 60 😖)

Is this new? It sounds deeply unattractive.

I don’t think it’s involuntary, seems to be a thing with men more than women. He sounds like an attention seeker tbh, I was on honeymoon and there was a guy just like this, was trying to relax around the pool in the Maldives, so was very peaceful and quiet. All I could hear was a guy very loudly hacking up phlegm, clearing his nose, coughing, burping etc it’s disgusting. There were loads of empty sunbeds around him so think he was annoying everyone else there as well. I don’t know how you live with this tbh!
