A bunch of sound experts have named the sound that humans find most annoying. Some of their picks are:
1. Vomiting.
2. Things our neighbors do that we can’t control, like construction or throwing a party.
3. Chalkboard scraping.
4. A loud artificial heart valve, which creates a loud, permanent sound coming from your body . . . even when you’re trying to sleep.
5. Voices of people you’ve been stuck with during the pandemic.
