In a two story house, how to insulate between upstairs and downstairs bedrooms?

In a bi-level house, there are two bedrooms, one directly under the other. There is a heat vent in the floor upstairs and ceiling downstairs. How can you insulate/sound proof between these two bedrooms?

Certainly as suggested the air vents will carry some of the sound, and they should not be compromised.

Blown in will not work, most especially not shredded news paper.

Carpeting above would help, with padding, but that's likely already installed?

I guess I'd have to ask how much noise from above, who is creating the noise, why, and maybe switch bedrooms.

There are other methods that would require changing the lower ceiling, as in acoustical tile, and/or drilling numerous holes in the lower ceiling and use aerosol foam insulator, in a low expansion formulation, but that too would require repairing the ceiling after the fact.

In your case there may not be a totally satisfactory answer, and with no offense meant I would not remove flooring or a ceiling, just to subdue some noise level.

Just my two sense

blowing in insulation is not the answer. unfortunately the sound will always travel through the heat ducts. there really is no way to prevent that without seriously compromising the flow of air. to stop sound travel through to space itself you are going to have to take up the floor or drop the ceiling. regular batt insulation works pretty good. especially if you have carpet on the floor upstairs. i recommend taking up the floor. i know it sound hard but actually the only skilled part of it comes when you remove and or replace the carpet.

once you remove the carpet just cut the floor out with a circular saw with the depth set just enough to cut through the sub-floor but not the joists. you can either replace the floor with new sheets or cut close enough to the joists that you can nail 2x 4's to the side of the joists to put the old pieces back. ( before you start ask someone knowledgeable to walk you through the process.) and while you have the floor up maybe to want to add outlets, phone jacks who knows.

if that isn't enough you could get a simple piece of rigid foam and put it over the vent when you are not using the air handling system. just make sure you put something on top of it: IE shoe book etc, to hold it down.

good luck. your struggling with a problem that has plagued parents and teens for years.

the cost wont be bad if you can reuse the sub=floor and you do the work yourself. but expect a solid weekend for someone who knows what they are doing. of course i would finish the whole thing in just under one hour ha ha ha

There is sound reducing systems on the market it is quite involved and will require the floor to be taken up and nsulation laid between the joists, and then insulation laid over the joists with a floating floor laid on top. Contact your council for the latest building regulation on this. There is no simple inexpensive solution apart from good quality carpet and underlay. Sp if you realy want to fix it it will cost

by using blow in insulation. Typically blow in insulation is made out of Finlay ground news papers and has a lot of r value. You can hire someone to do it, or check around at your local equipment rental centers and see if they have the machine to rent out. If they don't ask them for suggestions on where to find one or go on yahoo or google and start a search there.

I've no idea how you'll blow insulation between floors.

An acoustic ceiling may help. I'm not sure you can eliminate all the sound.

Carpeting and padding on the second floor may help some.

Heavy walking will not be eliminated.

Those vents are carrying some sound.

Use a soundproof plywood like they sell from supressproducts.com.
