What happens?

When you're flying very fast, there's that zoom sound that real-life air would make. It plays every time you do that, but if you lurk into the water and then fly out of it, this sound won't play

How to replicate it?

1. Put elytra on

2. Start flying from under the water

3. Fly into the air and start flying with high velocity (you might want to use fireworks).

Info: you might as well start flying from the surface, but you still need to fly into the water and then get out.
