I'm trying to come up with options for soundproofing around our water softener (and the mechanicals that go alongside it - not including water heater). Currently when it goes through it's regen cycle, it makes a lot of noise that echoes through the basement and upstairs (open concept to basement). Since this runs every few days, and we are planning to start our family soon, I would like to get this noise under control.
I've read several articles about soundproofing for a home theater, and am tempted to go that route, but I'm wondering if any one has experience with this. Do the home solutions (like double drywall with green glue) actually work for this, or is this sound a different frequency or some other properties that make that useless? Since it's such a small space, could I build up a box or covering with some MLV, and would that block enough noise? If I just layer up insulation, is it possible (within reason) to block the noise?
Or any other ideas that anyone has. I'm open for suggestions, preferably if anyone has done this before and can recommend do's and don't's.
