Hi,

I would like to insulate my kitchen ceiling for noise: my daughter's
bedroom is right above the kitchen separated from it by 3/4 pine and
nothing else.

I'm terribly allergic to fiberglass. I even stay away from insulation
isles at HD.

Are there other cheap alternatives to fiberglass if my only goal is
sound? I'm not gonna go with cellulose or something like that -- too
much work. But maybe something like cotton would work.

This ceiling will have IC rated recessed lighting cans in it.

Thanks in advance,

Aaron

Mass and isolation stop sound, not fiberglass or foam, etc. anyway.
Fiberglass or open cell foam is used to control reflection of high
frequencies off walls. At bass frequencies fiberglass and open cell
foam is virtually invisible to sound pressure waves. The bass is
probably what is bothering you.

Best solution is to use 5/8 inch sheet rock over resilient channel.
And recarpet the kids room with heavy rubber padding (mass) under the
carpet.

But the cheapest solution by far is to purchase high quality
headphones for the kid, mayby AKG701's or something like that, which
will actually reproduce the bass she seems to enjoy. Ear buds suck at
reproducing bass.
