urgent how to soundproof a room

hi everyone

just wondering how you could soundproof a room without major changes.

problem is the bedroom is in a partly enclosed veranda and the kitchen is on other side of the wall and you can hear things from in kitchen and you sometimes just want to hear tv or do something private or do work stuff plus the house is transportable.

what is a way to soundproof the kitchen wall between kitchen and bedroom without major changes, what have people used.

is there something you can stick to wall or is building another wall in front of the original wall to make it double thickness only way, am sure theres a easier way.

thanks

 

Cork walls?

 

Bigger sound system.

 

One of the new Sony, BOSE, Apple headphones.
You can't hear outside noise when you have that on your head.

 

ear plugs

 

Its impossible to "soundproof" unless you construct a bunker with solid mass walls eg filled besser block. What you will likely achieve is reduced sound levels. Post construction is difficult and each change may yield minor improvements and never quite be enough.

Transportable homes are usually very poorly constructed to save weight. The wall (internal and external) linings are thin, floors too, Insulation is possibly incorporated into insulated wall panels or vinyl boards and not high density glass fill. Ceilings are possibly just on thin framing and any fabricated internal walls are without much (or any) insulation. Its also possible its a piered house with a subfloor so noise will go through, up and over and under walls.

You cant "stick" things on walls to achieve the solution. Removing the whole internal adjoining wall on the bedroom side and installing dense fibreglass then reinstalling a higher density acoustic grade plasterboard may assist but still leaves up and under. Insulate celing and also add a layer of platerboard to internal...Cornice will need redoing but check ceiling heits allow the reduced height. Underfloor insulation may also assist with thermal and acoustic issues.

Be practical. Imagine trying to expect a RV has noise chareteristics of a double brick house ?

 

Take a walk inside a display home with a sound proof theatre room. You'll be amazed. Even with an open doorway you can hardly hear a sound coming from the theatre room.

This is achieved with acoustic plasterboard. Maybe some acoustic substances is fitted in the cavity wall as well.

 

On a slab ....and it was engineered with dense fibre infill (often rockwool). Display homes are often not same spec as a standard build and from scratch acoustic grade gyprock (2 layers) is not that expensive to install from scratch. Media rooms have the benefit that its more about absorbption IN the room so often fake suspended ceiling and soft wall panels etc have sound absorption so the room is dead. Absorbtion is heaps easier. Then trasmission is a minor issue. The OP issue is more transmission. Like a bedroom alongside a major road with traffic.

 

Or if on a budget egg trays

 

This is what I was going to suggest. It's what we done to the walls of the music room at high school back in the day.
Nowadays they likely just build the rooms better in the first place. Lol.
