Hello everyone, I’m currently looking into how to effectively soundproof an Ikea Pax wardrobe. The goal is to better isolate a device placed inside or conversations inside the wardrobe from the rest of the room, achieving a measurable reduction in transmitted noise. I know that furniture is usually not designed for sound insulation, and the Pax has relatively thin sides and doors. Does anyone have experience or tips on which materials could be used inside to improve soundproofing without affecting the functionality of the wardrobe or the opening of the doors? It’s also important to know if additional effort regarding stability or increased weight should be expected. I would appreciate practical suggestions and ideas that actually work and are feasible to implement. Thanks in advance!

I think that’s the most important point: without truly airtight doors, there will be significant sound leakage.
Besides that, it’s questionable whether insulation material actually absorbs sound or simply dampens it to some extent. The mass of the surfaces is usually crucial for soundproofing – a Pax has quite little mass. I would be concerned that it only helps minimally if you can’t access the construction from outside to reinforce it.
Another thought: what kind of sound exactly should be reduced? Low-frequency bass is difficult to isolate, while higher frequencies are easier. Depending on the source, different approaches are needed. This is an interesting aspect that the original poster might want to clarify further.

Make sure the door seals properly, otherwise you won’t gain much.

Hello Momete, I understand that you are looking for an effective solution since a Pax wardrobe is not originally designed to be soundproof. To improve this, you can try the following:
- Line the interior walls with acoustic foam panels or special sound insulation mats. These absorb sound waves inside.
- You should apply self-adhesive sealing strips to the doors to close any gaps.
- Additionally, you might screw a thin MDF board inside the side walls to increase mass. More mass means better sound insulation.
- You can also replace the back panel with a multi-layer construction containing insulating material in between to reduce sound transmission.
Materials like mineral wool are suitable but should not crumble and must be well enclosed, as they tend to be dusty and are not ideal for furniture. Also, ventilation should not be completely blocked, as this can cause moisture problems.
It is important not to rely solely on insulation, but on a combination of factors: mass, airtightness, and absorption. The more you can improve these three elements, the better the result will be.

As an additional note: the sound insulation of a piece of furniture like the Pax is naturally limited because the construction is not solid, and the cabinet acts as a hollow space that reflects and transmits sound.
I recommend improving the insulation of the room itself or addressing the sound source directly. If that’s not an option, the doors should be fitted with some type of soundproof sealing strips that use rubber profiles to create airtight seals.
Avoid materials that trap moisture or seal the interior completely, as this can promote mold growth.
The key factors are the combination of:
- Increasing surface mass (e.g., by adding extra MDF panels inside)
- Changing the volume and applying internal absorption (sound insulation panels or foam)
- Airtight seals on doors and edges.
Without these three aspects, the effect is hardly noticeable.
