What is Loud, whistling sound?

A loud, whistling sound is like when you blow air really fast through a narrow space, making it go whoosh.

Imagine you have a toy train that goes choo-choo. Now imagine the wind blowing through a tiny tunnel, that's what makes the whistling sound. It’s very loud, so it can be heard from far away, just like when your brother blows really hard on a kazoo.

When air moves quickly through something small, it creates a whistling sound. This is similar to how you make noise by blowing across the top of a bottle, brrrrr! The faster the air goes, the louder and more whistling the sound becomes.

Sometimes, when things like wind or machines move fast through small spaces, they can create these loud, whistling sounds, just like your toy train or a real train on the tracks. You might hear this sound when you're outside on a windy day or near a busy highway, it’s the air moving fast and making noise!
