Crossmodal perception is when senses interact in sometimes surprising ways. Some fun examples:
Coffee tastes better when you don’t have a loud coffee machine near you, and it also tastes more intense and less sweet if the mug is white.
In the atmosphere of a pressurised cabin when flying, with decreased humidity and air pressure and significant background noise, things taste less sweet or salty.
If you can’t hear the crunch of, say, a Pringles potato chip, then it tastes less fresh.
