Very loud when AC is on

Hi,

Don't know if this is normal or not.

When the AC is on, the engine sound becomes very loud.
Is there something going to break? Or this is just the way it should.

I have been driving other cars which don't seem to have that loud sound when AC is on.

Many thanks for help.
