I am finishing my basement. This is just a "general use" basement, not a media room or anything like that. But, the television in the basement will be located directly under our master bedroom. The basement ceiling will be a drop ceiling and I intend to use tiles with decent sound absorption. The joists are 2 x 10 16" OC. I am planning to put some fiberglass insulation in the joists. I realize this will be of limited value but I think it will be better than nothing. I will probably use unfaced fiberglass with the wire rods to hold them in place. Should I use R13, R19, R30 or even R38? Does the thicker insulation make enough difference in sound to make it worth the extra money?
