The best sounds for blocking out neighbours
Muffled voices through the wall. Bass from their music. Footsteps at midnight. The unpredictability is the worst part — you're always waiting for the next intrusion.
How sound helps
Low-Frequency Masking: Low-frequency noise - traffic rumble, bass from neighbours, HVAC hum, footsteps from upstairs - passes through walls and floors more effectively than high-frequency sound. White noise (equal energy across all frequencies) is less effective at masking these bass-heavy disruptions. Brown noise concentrates its energy in the low frequencies (-6 dB/octave), making it the most effective masking option for urban environmental noise.

Setup guide
Place the speaker against or near the shared wall. This creates a "sound barrier" that intercepts the noise before it reaches you. For sleep, a speaker on the nightstand facing the wall works well.
Recommended sounds
brown noise
Direct counter to bass-heavy neighbour noise. The deep frequencies fill exactly the range where voices and music bleed through walls.
Recommended: 50-65 dBthunderstorm sounds
Heavy rain + distant thunder provides layered masking: rain covers voices, thunder covers bass impacts. More engaging than pure noise.
Recommended: 50-65 dBwhite noise
When you need maximum broad-spectrum masking. Covers everything from bass to treble. Less comfortable for long periods but most powerful for severe noise.

Pro tip
If voices are the main problem, try layering brown noise with a fan sound — the combination covers the full speech frequency range (300 Hz-3,000 Hz) extremely effectively.
Frequently Asked Questions
Can sound machines actually block neighbour noise?
"Block" is the wrong word — they "mask." The neighbour's noise doesn't disappear; it becomes indistinguishable from the background. For truly loud neighbours, combine sound masking with physical solutions (weatherstripping, door sweeps, heavy curtains).
