Hi all,

What is the best material for noise-insulating a stud partition wall?
Simply stuff in some loft insulation or is there a better way?

Thanks!

Build a second one spaced away from it.

Will make little difference - you need mass for sound insulation. Perhaps
the cheapest option is to add an extra layer of plasterboard.

Thanks!

Yup. Air gaps is the first thing to get rid of, then add mass.

fluffy insulation reduce HF passthrough by damping, but not MF or LF.

You need stiffness or mass to reduce that.

Consider removing plasterboard, screwing/nailing MDF or ply and
replacing plasterboard on top.

Foam filling would stiffen it even more.

Thanks!

Waste of time and money. Plasterboard is better at stopping sound
transmission than either MDF or ply of the same thickness. Because it's
denser. So just add plasterboard on top of the original. Cheaper too.

The MDF is a little stiffer though.

Not sure but suspect that would reduce low frequencies.

Quite true.
Although it makes the wall seem a lot more "dead", i.e. it does not
sound or feel hollow when you knock it or lean on it etc. This does
make it seem a lot more "solid".

All the following can help:
Double layers of plasterboard
Foam or rockwool fill
Add weight with concrete blocks sat on noggings
Stiffen the timber framing, either with large-ish timber or metal bars
Apply damping sheet material to the PB
Create 2 sets of uprights staggered so there's no transmission of
vibration through the framing

You need decoupling of the two surfaces: thad means separate sets of
uprights for the two sides. They can be 'interleaved' but should not
be coupled. this stops sound transmission through the wood. i.e one
side's platerboard is fixed to one set of uprigths, the other side to
the other set. This is very importnat if yo uwant maximum isolation.

You need mass: each side should have a double thickmness of
plasterboard.

You need good caulking: fill around the edges to stop flanking paths.

You need 'loft insulation' inside to stop transmission through the
air.
