Soundproofing a shared wall

[Annahmed]

Hi everyone! What are some of the best ways to soundproof a shared wall in an apartment without making major structural changes? I’m looking for affordable solutions that effectively reduce both airborne and impact noise. Any tips or product recommendations would be greatly appreciated!

Hi there! To effectively soundproof a shared wall in an apartment without major structural changes, start with acoustic panels or foam tiles, which can absorb airborne noise and are easy to install using adhesive strips or hooks. Adding a tall, filled bookshelf or a heavy cabinet against the wall can also create an extra sound barrier while serving as storage. For more robust noise reduction, consider hanging mass loaded vinyl (MLV) on the wall, which is dense enough to block sound but flexible for easy installation. If you’re looking for a simpler solution, soundproof curtains or blankets can be hung directly over the wall to dampen noise quickly. Finally, sealing any gaps or cracks along the wall edges with acoustic caulk ensures that sound doesn’t leak through small openings. These options are renter-friendly, effective, and require minimal effort.

Thanks! Do you think combining two of these options, like MLV and acoustic panels, would make a noticeable difference?

You're welcome! Absolutely, combining mass loaded vinyl (MLV) with acoustic panels can make a big difference. MLV is excellent for blocking sound while acoustic panels are great for absorbing it, so together they tackle noise from both angles. Think of MLV as the shield and the panels as the sponge, they complement each other really well. If you’re dealing with serious noise, layering these two would definitely step up your soundproofing game!

I like how they work together to cover both blocking and absorbing sound. Definitely sounds like a solid approach. Thanks for the helpful advice!
