How to Quiet a Home Office When You Share Walls

Last updated: April 2026 · 9 min read

Working from home in a noisy apartment means two problems at once: external noise breaking your focus, and your own calls and keystrokes disturbing your neighbours. This guide addresses both sides. Every recommendation is renter-safe, and most can be set up in a single afternoon.

Choose the Right Room (or Corner)

If you have any flexibility in where you set up your desk, use it wisely. The best home office location in a noisy apartment is the room (or corner) that shares the fewest walls with neighbouring units and is farthest from the street.

• Interior rooms with no exterior walls are naturally quieter.
• If every room shares a wall, choose the room where the shared wall faces a closet or bathroom on the other side, not a living room or bedroom.
• Avoid setting up directly against a shared wall. Even moving your desk 2 to 3 feet away from the wall reduces how much you hear through it.

If you are working from a studio or one-bedroom, a corner diagonal from the shared wall is your best bet. The farther you sit from the noise source, the more the sound dissipates before reaching you.

Treat the Shared Wall

The wall between you and your neighbour is the main noise path. Treating it does not require construction. Layer these approaches for the best results:

• Heavy bookshelf: A tall, filled bookshelf against the shared wall acts as a mass barrier. This is the single most effective furniture-based solution.
• Acoustic panels: Mount 2-inch fibreglass or dense felt panels on the shared wall behind and around your desk area. They absorb incoming noise and reduce echo in your own calls.
• Mass-loaded vinyl: For serious noise, hang a sheet of MLV behind the bookshelf. It is invisible and adds substantial sound blocking.

Seal the Door

A closed door with good seals is surprisingly effective. Most interior doors have a half-inch gap at the bottom and no seals around the frame. Fix both:

• Door sweep: Self-adhesive or clip-on models seal the gap at the bottom. Choose one rated for sound, not just drafts.
• Weatherstripping tape: Apply foam or rubber strips around the door frame so the door compresses against them when closed.

A properly sealed door can reduce noise by 5 to 10 decibels. That is enough to turn audible conversation from the next room into an indistinct murmur.

Reduce Echo for Better Calls

Even if you cannot fully block external noise, reducing echo in your office makes a big difference on video calls. A room with hard walls and floors reflects your voice, creating that "calling from a bathroom" sound. Your call participants hear the echo, and your microphone picks up more ambient noise in a reverberant room.

• Area rug with a thick pad: Covers the floor reflection.
• Acoustic panels behind your monitor: Absorbs the reflection that bounces from the wall behind your screen back toward your microphone.
• Soft furnishings: Upholstered chairs, throw pillows, or a couch in the room all absorb reflections.
• Bookshelf behind you: Acts as a natural sound diffuser and absorber on camera background too.

Use a Noise-Cancelling Microphone

Your headset or microphone matters enormously for call quality in a noisy environment. Consumer webcam microphones pick up everything in the room. A good noise-cancelling headset isolates your voice and suppresses background sounds like traffic, construction, and neighbour noise.

Look for headsets with active noise cancellation for what you hear, and a directional or noise-cancelling microphone for what your callers hear. These are two separate features, and both matter.

Software Noise Suppression

Modern video conferencing tools (Zoom, Teams, Google Meet) include built-in noise suppression that filters out background sounds from your microphone feed. Make sure this is turned on in your app settings. Some dedicated apps like Krisp provide AI-powered noise cancellation that works across all audio applications.

Software suppression is not perfect, especially with loud or sustained noise, but it is free and provides a meaningful improvement on top of your hardware and room treatment.

White Noise for Focus Work

When you are not on calls, a white or brown noise machine keeps you in a focused state by masking the intermittent noises that break concentration: a door slam, a neighbour's laugh, a car horn. Research consistently shows that consistent, moderate ambient noise improves focus more than silence (especially when silence is punctuated by random disruptions).

Place the machine on your desk or between your desk and the primary noise source. Keep the volume low enough that it fades into the background. Brown noise (deeper, rumblier) is often preferred for long work sessions as it is less fatiguing than higher-pitched white noise.

The Complete Home Office Setup

Here is the full checklist, ordered by impact relative to cost:

1. Seal your office door with a sweep and weatherstripping ($10-$20).
2. Position your desk away from shared walls and windows (free).
3. Add a thick area rug to reduce echo ($30-$100).
4. Mount acoustic panels on the shared wall and behind your monitor ($40-$120).
5. Use a noise-cancelling headset for all calls ($50-$200).
6. Place a bookshelf against the shared wall, filled with books (varies).
7. Run a white noise machine during focus hours ($20-$50).
8. Enable software noise suppression in your video conferencing app (free).

A budget-conscious setup of door seals, a rug, and a noise-cancelling headset costs under $100 and handles most situations. For a dedicated home office in a very noisy building, the full stack with acoustic panels and a bookshelf barrier brings professional-level quiet without touching the lease.
