A Sound Library Designed for Your Needs
We've carefully curated a collection of high-quality sounds to help you relax, focus, and sleep better:
- White noise, brown noise, and dark noise - Perfect for masking disruptive sounds and creating a consistent sleep environment
- Nature sounds - Rain sound for sleep, ocean waves, crackling fire, fan sound for sleep, and morning birds transport you to a peaceful place
- Meditation and focus sounds - Ambient tracks and soft instrumentals help you concentrate during work or practice mindfulness
- Baby sleep sounds - Familiar sounds like hair dryer, vacuum cleaner, and keyboard typing help little ones drift off to sleep
You can mix any of these together: white noise under ocean waves, rain over soft meditation music, or whatever combination helps you switch off. Mixing is unlimited and included in the free version.
How Sound Masking Helps You Fall Asleep
Sleep research on noise masking points to a simple mechanism: your brain reacts to changes in sound more than to sound itself. Steady audio helps in three ways:
- Masks disruptive noise - Traffic, neighbors, snoring, and sudden sounds blend into the background instead of standing out
- Signals your brain to rest - The same track every night becomes a cue that it's time to wind down
- Reduces nighttime awakenings - A constant sound floor makes you less likely to be startled awake by one-off noises
App Store reviewers most often mention falling asleep faster when background noise was the thing keeping them up. Results vary by person, so preview a few tracks and give one a full week before judging it.
Focus Sounds for Work and Study
The same masking that helps at night works during the day. If you study in a shared space, work from a coffee shop, or sit in an open office, steady sound covers the conversations and clatter that break concentration:
- Brown noise for deep work - Lower frequencies feel warmer than white noise and are easier to listen to for hours
- Ambient and instrumental tracks - Background texture without lyrics that pull your attention
- Saved mixes - Keep one blend for sleep and a separate one for work sessions
- Offline playback - Focus sounds keep playing on a plane or anywhere without signal
Reviewers who use DRMN during the day mention studying, open-plan offices, and writing sessions as the most common use cases.
Baby Sleep Sounds for the Nursery
DRMN includes sounds parents already know work: hair dryer, vacuum hum, and keyboard typing. These steady, low-variation rhythms resemble the constant background noise babies heard in the womb, which is why they settle infants when silence doesn't.
Set the timer if you only need sound while your baby falls asleep, or use offline playback for all-night sessions without keeping the phone online. An old iPhone in the nursery running DRMN replaces a dedicated bedside sound machine.
