Background noise too loud

Can someone please be kind and show me how to decrease background noise? When driving, I find the noise too loud such as tyre and engine rumble. At work, I find the fridges too loud. At home I find the extractor fans in the bathroom too loud. Are my compression settings out of whack? The MPO’s are set quite low so they may not be the issue.

Thank you
