there are sheilds, but really only for the advanced navies like prometheus. and sonic weapony have never worked in the real world(and are pointless anyway, because if you have a sheild like that, you'd have tech for space travel, and then those weapons wouldn't work anyway.). the only weapon I think would work would be some kind of either laser or MAC(or normal guns if need be).
