No. It's not the same as just not liking eating sounds. Obviously no one loves them. I think it is almost impossible to convey it to a non sufferer. As many of the responses on here demonstrate.
For me it creates a sort of 'fight or flight' reaction. My whole self is overcome by whatever the sound is. I cannot tune it out. I feel so incredibly furious, like I want to rip my ears off, scream and shout and throw things. It feels like pure torture. In that moment, I am filled with genuine disgust and hatred at whoever is making the sound. The closer the person to me, the worse I am affected. So it doesn't matter how quietly my DH tries to eat, I can't bear to be around him unless we are in a big group or noisy public place. It's not just normal eating noises, it's him breathing so I can hear it as well. I don't generally notice when other people eat or breathe things unless they are especially loud. Generally I am mainly affected by people I don't know chewing gum or eating apples, and will move away from them in a public place. But with my DH, and my mum, it's anything they eat. I have to wear earplugs at home a lot.
Equally I cannot 'be kind' as a pp has suggested. It's really not that simple. Its a physical, nervous system reaction. I have no control over my reaction- as in I cannot stop myself from feeling this way. Obviously what I can do is try and minimise my exposure to sounds that trigger me - and I do try very hard with this, but DH doesn't always get it and will start eating something in front of me - if I can't leave the room then this is genuine torture. It sounds so dramatic to someone who doesn't have it. But it genuinely makes me want to cry and scream. I can feel my blood pressure rising and feel so incredibly stressed and anxious.
It's really not as simple as just 'not liking eating noises.' I hate it. I wish there was a cure. It takes all of my self control to deal with it. My mum and DH (when he remembers) will help me by going into a different room to eat etc, and not getting cross if I won't eat with them. I seem to have super sensitive hearing which doesn't help, and if I tune into a noise like an unexplained rattle in the car, it can invoke the same reaction. It's horrible and I wouldn't wish it on anyone. Mine started when I was about 11.
