Science question - noise & fog

As you describe. The fog allows the soundwaves to carry better as the water droplets are denser than dry air. However, they distort your directional sense of hearing, so sound appears louder, but you cannot pinpoint the source. It works even better underwater, where sound is transmitted direct to your ear (or the bubble of air in your outer ear) but you cannot determine direction

Yebbut. Geese are useless underwater.

So, if a goose cuts a tree down underwater and you're wearing earplugs will it still make a sound?

Only if the other hand isn't clapping as well.

Breaking wind in the bath is a good demonstration of this one!

I alwys remebre manyyears ago that I was taught that when driving in thick fog you should open the windows to enhance your hearing and get additional warning of other vehicles

There's no need for that, thank you. Cubists explanation was fine.

depends on how loud the chainsaw is

When my Mum was young, back in the 50s-ish, she and a friend were driving back from Norfolk to Leicester, in a thick Fenland fog, at night. In those days, the A47 crossed the A1 at a simple crossroads, and the fog was so thick that while her friend drove, my Mum had to get out and listen for traffic on the A1 before they drive across!

Of course, the A1 wasn't quite so busy in those days, but even so....

Readers, I suggest you don't follow through with this suggestion.

If you were in the bath by yourself you would have a pretty good idea where the sound came from and this would render the demonstration useless.

It would work better with several people in the bath. One farts and the others would have to try to pinpoint the source!

Or you could bottle it.

I think he's pretty brave
