One of the worst things you can do to your hearing is to drive with the
window down. There are huge LF waves set up in your car that you don't
really hear, but the hair cells in your ear get broken as a result.

If you only have one window open and the wind is right, it can make a
sort of 7- or 8-Hz whistle out of the interior, very uncomfortable.


Which is why I've been driving with earplugs for anything over 30 minutes since about age 25.

You know you should wear ear plugs when you eat breakfast too. Those
snap crackle pops sounds are known to cause catastrophic high
frequency hearing loss as well as severe psychological trauma.
