Dive underwater in a pool while a radio is playing near the pool. While you are underwater, the sound of the radio will be different because the sound waves which are traveling in air at first, encounter water, and must travel through water to reach your ears. So it goes from the medium of air to the medium of water.

Diving for underwater exploration
Flying with blocked ears is not necessarily dangerous. However, you want to find out why your ears are blocked before you fly.

It is blocked by air.
When they go underwater, their ears and mouth seal so they don't get water in them, this helps them stay underwater for a solid 15 minutes.
yes but usually when i do it my ears always pop
up to 90%
If you were being blocked you would not be able to post this question.
Sounds, which are nothing more than vibrations, can actually be heard better and further underwater than in air. So I would think frog's ears would be useful both underwater and sitting on land, to detect noise/vibrations of predators and to detect mates.

I'm pretty sure worms don't have ears. They don't really need ears since they spend time underwater or in the ground where its hard to hear anything.
Does yelling hurt your ears? Sound travels faster underwater but it also loses loudness. Whales ears are also less sensitive to human frequencies.
