I have a friend who is hot, but she has the loudest, most annoying, longest laugh I have ever heard. There will be a group of us out having a great laugh, and then silence as us and onlookers stare in amazement. Judging by this chart https://www.tlc-direct.co.uk/Technical/Sounds/Decibles.htm I am guessing 100 decibels of annoyingness. She is a good girl, hot, but that laugh is a deal breaker.
