I am in the inflatable amusement business and we have a big inflatable movie screen. The blower is the same style used with my squeeze room. I'm not sure what size your blowers are, but either way.....open air cinemas is who made my movie screen and they offer a "silent" blower box because you can imagine watching a movie with those things going. You should check out their website, I'm not sure how much they are but they make it really quiet. I'm sure you could build one yourself for cheaper though.
