How much better would a solid door block sound?

Much better. If you are talking about the plain luan mahogany
doors, even the molded panel doors are better.

Thanks, any particular doors better at this?

You'd probably be better off hanging some sound-absorbing material on
the outer surface of the door.

The hollow core door is probably reverberating the sound waves. A
molded panel door or a solid core door would probably be better than
what you have. But, the door skin of either type (the molded/textured
or solid core) will still be a relatively flat surface the sound waves
will hit and transfer the noise to the bedroom on the other side.

Although I'm not an expert on this topic, I think you'd be better off
by utilizing some sort of material that absorbs sound being affixed to
the outer door skin.

Try hanging anything on the outer face of the door before replacing
the door you have. Simply hang a sheet - folded to produce numerous
layers of material - from the top of the door. Or, place one or more
coat hooks on the outer side of the door and hang jackets, flannel
shirts, or housecoats from it.

It would probably help to hang the material a small distance from the
door surface to further reduce transmission of the sound waves from
the hung material to the door skin. Use a curtain rod, a wooden dowel,
or whatever else is suitable to drape the material over and allow an
air gap between the material and the door skin.

Clothes hooks typically hold garments several inches from the door
skin. That will be beneficial in reducing noise intrusion into the
bedroom.

If you can't, or don't want to, screw anything to the door, buy the
type of clothes hooks that slip over the top of doors and hang
something from that/them. Here some types I found online:

You could use a door-mounted shoe rack like this, or modify it to hold
other items, which will absorb the sound waves hitting the door -

Thanks for the info.


Before you try any of these things do a little research on the web on
sound transmission. Generally the best defenses against sound
transmission are mass, and sealing openings. So if you have a big gap
between the door and floor, that would one area to address. To add
mass, yes get the heaviest solid door you can find, or for a quick and
dirty solution screw a sheet of drywall to the existing door. Can be
on inside or outside. -- H
