Sleep Sound: Brown Noise Mask

Struggling to sleep because of upstairs neighbor noise?

Sleep Sound masks the footsteps, door slams, and impact noise from above with carefully curated ambient sounds. Every sound in our catalog is chosen to effectively cover the low-frequency intrusions that keep you awake at night.


■ Why Sleep Sound?

Most sleep sound apps loop for 20 to 60 minutes. That doesn't cover your actual sleep. Sleep Sound is built from the ground up for infinite overnight playback — it keeps going until you stop it. Where other apps produce audible gaps every time the audio file loops, Sleep Sound uses a dual-player crossfade engine to deliver truly seamless playback all night long.


■ Sounds designed for real apartment noise

- Brown noise variants at multiple intensities (relaxing, medium, hard, very hard)
- Spatial brown noise for immersive coverage
- Crunchy-texture brown noise
- Heavy rain ambient
- Airplane cabin noise (steady low-frequency alternative to white noise)

Regular rain apps use high-frequency samples that don't mask low-frequency footsteps very well. Sleep Sound's catalog is intentionally chosen to cover the frequency range where apartment noise actually lives.


■ True infinite playback

- Plays indefinitely — no time limit
- Dual-player crossfade eliminates loop-point artifacts
- Reliable background playback via Android Media Session
- Lock screen and Bluetooth headphone controls work out of the box


■ Minimal by design

- Simple one-tap UI perfect for bedtime
- Pause and resume from the notification shade
- Full dark theme (this is an app you turn on at night)
- No progress bars, no clutter — just choose a sound and sleep


■ Completely offline, no data usage

All sounds are bundled with the app. There's no streaming, no waiting, and no internet needed. Play all night without touching your data plan. If your Wi-Fi drops, the sound keeps going.


■ Privacy-first

- No sign-up required
- No microphone, location, or contacts access
- No email collection
- Minimal advertising


■ Made for

- Apartment dwellers dealing with upstairs neighbor noise
- Light sleepers who wake at the slightest disturbance
- Anyone seeking deep, uninterrupted sleep
- Users who want a sound app that just works, offline
- People who already fall asleep to white noise or brown noise


Reclaim your nights. Download Sleep Sound and sleep through whatever's happening upstairs.
