This is what a frozen lake sounds like

It was an hour into the new year on January 1st, and I was on the shores of a frozen lake in Rikkenstorp, a few hours from Stockholm. My friends and I had rented a house to spend a lovely New Year’s Eve playing board games and eating insane amounts of food. After toasting to the beginning of the new year and before heading to bed, we decided to go out to watch the stars. And that was when I witnessed the most amazing thing I’ve ever heard.

Impressive audio. Wouldn’t expect ice to sound like that.

lower frequencies take longer to reach the ear than higher frequencies

if they all took the same time it would sound different again

they do? can you back that up?

Will TATE do?

The speed of sound in an ideal gas depends only on its temperature and composition. The speed has a weak dependence on frequency and pressure in ordinary air, deviating slightly from ideal behavior.

Did you read the article?

5th paragraph

This ice shifting causes all kinds of sound frequencies, high and low. The vibrations move through the ice, but the high frequencies move faster than the low frequencies and reach your ears first, explains NPR’s Skunk Bear. That time lag makes the lake sound like a cracking whip.

its actually a very interesting little video

long wire fences can make similar noises, like twang

Question
Why does sound travel faster in solids than in liquids, and faster in liquids than in gases (air)?
Asked by: Will K

Answer
Sound is nothing more than a local disturbance whose propagation is facilitated by the collisions between particles; this disturbance propagates in a logitudnal wave; imagine one molecule hitting the next molecule, and then that molecule hitting the next, and so forth.

The distances between molecules in solids are very small, i.e., solids are more dense – as compared to liquids and gases. Because they are so close, than can collide very quickly, i.e. it takes less time for a molecule of the solid to ‘bump’ into its neighborough. Solids are packed together tighter than liquids and gases, hence sound travels fastest in solids. The distances in liquids are shorter than in gases, but longer than in solids. Liquids are more dense than gases, but less dense than solids, so sound travels 2nd fast in liquids. Gases are the slowest because they are the least dense: the molecules in gases are very far apart, compared with solids and liquids.

Science – Transmission of Sound

Two ideas come to mind.

The first was the sound is of bursting bubbles. As ice freezes it expels dissolved gases as bubbles. These burst creating one of the loudest sounds in the ocean.

The second is that the recording was probably made underwater. All underwater sounds are a bit like that.
