I have often wondered if I have misophonia, as certain sounds make me irrationally ratty.
Sniffing and gum-chewing are the worst but I also get angry with finger tapping and people who shout on their mobile phones.
My friends say it’s misanthropy rather than sound-sensitivity. But a study has revealed that a fifth of Brits now suffer from misophonia and feel anger, disgust or panic in extreme reactions to noise.
