If a sound is loud, you can hear it very easily. If it's very loud, it might hurt your ears.

Example: Can you turn down the music, please? It's too loud.

If a person is loud, they talk too much or too loudly.

Example: After he has a few beers he gets really loud.

If colours, clothes, or other things you see are loud, they have too many bright colours or patterns and they don't look good.
