Banished Ogres tend to louder than expected, especially when they're hit with an attack.
It's been awhile since I've heard, but has that occasional loud lightning strike when playing an empire faction been taken care of?
Other than that, I've thought the game to be fairly balanced for sound (and I've been paying attention because I had that game start book sound problem since 0.951 that was fixed in 0.983.) versions are approximate.
