basement floor joist insulation for sound control

I am planning to install R-19 insulation between basement floor joists to provide sound insulation from the basement (teenage tv and stereo). I was going to use the paper faced fiberglass with the paper facing down to get a compression fit between joists. Some of the insulation will be above a drywall basement ceiling and some above a suspended basement ceiling. Are there any long term problems with doing this installation?

Thanks in advance for your advice.

Get insulation support wires (they wedge between the joists to support the insulation) for the areas above the suspended ceiling.

Bungalow Jeff,

Thank you for responding.

Does it technically matter whether I use the kraft faced or non-faced? Are there any long term benefits / problems using one or the other?

I believe the benefit of the craft faced insulation ios the nailing strip. The paper does not constitute a vapor barrier.
