About the only way to do it right now is to directly modify the sound files in <steam folder>\Life is Feudal Your Own\art\sound\SFX.
Use a sound/music program like Audacity (free) and re-save the .ogg file with the amplitude turned down on the file. For the bloomery, i think you're looking for env_fire.ogg in that folder.
Edit:
I also noticed a env_fire_small.ogg in the folder, it is not as loud as the fire or over sounds, you can also copy it twice and replace/rename the fire and over sounds with the small and it will be quieter.
