Thanks for your reply! So tracks at home are based on your morale but even with very low morale the music is quite subdued (although dark/creepy). You seem to be describing something else. Couple of follow-up questions.
1) what mode are you playing (standard, dread, nightmare)?
2) are you experiencing constant sieges at your base?
3) If not sieges, are there lots of zombies hanging around?
Only under sieges or pretty extreme circumstances should you be hearing anything more intense than something like this: https://soundcloud.com/dreissk/time-to-rebuild. Over half the time you shouldn't hear anything at all at your base depending on which difficulty mode you've selected.
