Well one solution would be to have their noises quiter for when your running around but when you go into sneak mode, your character will focus, and will tune out other nosies essentially making all noises slightly more quiet but increase the sound of the animals

The effectiveness could be effected by the sneak skill maybe?
I just want a peaceful base (no annoying animals making mating calls 24/7) without sacrificing the raids, Cause i like those
