It’s so hard to control how you sneeze, and it’s true. However, you obviously have some control over what your mouth says when you sneeze. According to the BBC, when an English speaker sneezes, he says “ahhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh-hhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh.

“It’s natural for deaf people to sneeze, and people with hearing feel they have to make a sound,” wrote Charles Winborn, a blogger for deaf people in the UK Swinburne is a semi deaf person.

In other countries with different cultures, people with normal hearing will produce different “sound effects” when sneezing, which shows that it is not involuntary to make a sound when sneezing. For example, the French say “ahshu!”, the Japanese say “hakachu!”, which sounds similar, but not exactly the same.

Ben Sewall, a researcher at University College London, explained that sneezing does cause certain voices that people can’t control, but people have the ability to modify the voice so that it doesn’t seem abrupt in interpersonal communication. So is laughter. You make a sound when you laugh, but you can lower or amplify it.

“When people with normal hearing feel like they’re going to sneeze, their brains send out a warning:” emergency! Sneeze! Public! Make your voice normal! “Swinburn said.” they make a special sound in an instant: ah – out! “

Hoping to make the same sound as others, this kind of unconscious pressure can even affect some deaf people like Swinburne. He wrote that he would “go out” unconsciously in public, while sneezing at home was much less.
