Walls & Shared Surfaces

Shared walls transmit neighbor noise easily, especially in multi-unit buildings with lightweight drywall. You cannot alter structural walls in rentals, but you can add mass, absorption, and spacing to reduce sound transmission. These guides focus on reversible, rental-friendly solutions like furniture placement, fabric panels, and decorative sound barriers.

Bookshelf against shared wall

Using Bookshelves for Wall Soundproofing

Filled bookshelves add mass and air gaps to shared walls, absorbing sound energy. Position heavy units against noisy walls, fill every shelf, and leave a small gap for additional sound isolation. This method is lease-compliant and improves acoustics.

Quick Fix
Fabric wall panels

DIY Fabric-Wrapped Acoustic Panels

Create removable sound-absorbing panels with wood frames, insulation, and decorative fabric. Hang with Command strips or picture rail hooks. These panels reduce echo and absorb mid-to-high frequency noise from voices and media.

Tapestries and Heavy Wall Hangings

Thick tapestries, quilts, and canvas art absorb sound waves and add visual warmth. Hang them on shared walls with damage-free hooks. This quick, low-cost solution works especially well for reducing echo in hard-surfaced rooms.

Acoustic foam alternative

Acoustic Foam vs. Fabric Panels

Acoustic foam excels at absorbing high frequencies but does little for bass or impact noise. Fabric panels offer broader frequency absorption and look better in living spaces. Learn when to use each, how to install safely, and which is more rental-friendly.

Quick Fix
Furniture against wall

Strategic Furniture Placement

Place sofas, wardrobes, and tall dressers against shared walls to create a buffer zone. Upholstered furniture absorbs more sound than hard wood pieces. This guide shows optimal spacing and arrangement for noise reduction without sacrificing layout function.

Picture rail system

Picture Rail Isolation Tricks

Hang heavy frames, mirrors, or fabric-wrapped boards from picture rails to avoid drilling into walls. This creates a small air gap that disrupts sound transmission. Ideal for older buildings with existing rail systems.

What NOT to Do to Rental Walls

Never drill large holes, attach permanent materials, or attempt to open wall cavities in a rental. Avoid spray foam, construction adhesive, or any modification to fire-rated assemblies. This guide clarifies lease restrictions and strata rules.
