I just put in recessed lighting and lost a lot of soundproofing in the room. There is some insulation in the ceiling, but since cutting the holes in the drywall, sound is leaking out like crazy (understandably). The lights are LED and rated to be up against insulation, but I know rockwool is really good at sound dampening. I wondered if I could pull down the LED lights, and then stuff rockwool up above to reduce sound leaking through the light holes. I know it's not like fiberglass, so is it possible to stuff in there?
