What is Noisely?
Noisely is a free online platform offering white noise and natural sounds to help improve sleep, focus, and relaxation. Mix rain, wind, bonfire, and more to create your perfect ambient soundscape.
Unlike a physical white noise machine or a subscription app, Noisely runs entirely in your browser: nothing to install, no account, and no paywall. Every sound can be layered with others and given its own volume, and some sounds (like distant thunder or a cat's meow) play at intervals you control, so the mix feels natural instead of looping. People use it to fall asleep faster, block out chatter while studying or working remotely, soothe a newborn, or simply unwind after a long day.
How to Use
Choose Sound
Select your favorite sounds from the sound library, click to add to the player and start playing.
Adjust Volume
Each sound can be independently adjusted in volume to create the perfect sound mix. Some sounds (such as muffled thunder, cat, turning pages, etc.) support adjusting playback intervals for a more natural experience.
Mix Sounds
You can play multiple sounds simultaneously, layering them together to create unique soundscapes.
Set Timer
Set a timer to automatically stop the sound after a specified time, perfect for bedtime use.
A Guide to Every Sound
Every sound in the library was chosen for a reason. Here's what each one is good for, grouped by how most people use them. Treat it as a starting point, then trust your own ears.
For Sleep
Steady, low-detail sounds that mask sudden noises without asking for your attention.
- Rain
- Rainfall spreads its energy across a wide range of frequencies, much like pink noise, so it covers traffic and voices well. Its irregular patter sounds less artificial than static, which is why it's one of the most popular sleep sounds.
- Cricket
- A soft, rhythmic chirp that signals a quiet summer night. It sits in the higher frequencies, so it pairs well with a deeper sound like bonfire or rain underneath.
- Field Frogs
- A distant chorus of frogs adds an open-air, countryside feeling. Keep it low in the mix; a little goes a long way.
- Air Conditioner
- A constant mechanical hum that many people already associate with sleep. It's close to brown noise and is good at masking low-pitched sounds like a neighbor's TV.
- Cat Purring
- A low, steady purr that many listeners find instantly comforting. It's gentle enough to play all night without becoming tiring.
- Tidal
- Waves rolling in and out follow a slow rhythm similar to relaxed breathing, making them a natural fit for winding down or a short meditation before bed.
For Focus
Background activity that gives your brain just enough stimulation to stay on task, the so-called coffee shop effect.
- Keyboard
- Steady typing creates a sense of momentum. It's a subtle cue that work is happening, useful when you're working alone or struggling to get started.
- Writing
- Pen on paper is quiet and intimate. It suits reading, note-taking, and study sessions where you want company without distraction.
- Turning Pages
- Page turns play at intervals rather than continuously, recreating the calm atmosphere of a library or study hall.
- Train
- The rhythmic clatter of a train is a classic masking sound: loud enough to cover office noise, steady enough that your brain quickly tunes it out.
- Noisy
- Indistinct crowd chatter. Some research suggests a moderate level of ambient noise can support creative thinking. Keep it in the background so no single voice stands out.
- European Square
- Footsteps, distant conversations, and city life from a European plaza. A favorite for remote workers who miss the buzz of being around people.
For Relaxation
Natural soundscapes for unwinding, reading, or taking a mental break.
- Stream
- Water running over stones is bright and lively. Blend it quietly under forest sounds for an outdoor walk without leaving your desk.
- Forest
- Birdsong and rustling leaves. Natural sounds like these have been associated with lower stress in several studies, which makes forest a good choice for short breaks.
- Bonfire
- Crackling wood adds warmth and texture. It's one of the most versatile sounds, working equally well for reading, winter evenings, or as the base of a sleep mix.
- Breeze
- A light breeze moving through open space. Soft and airy, it fills silence without adding much detail.
- Mountain Wind
- Stronger, deeper gusts than the breeze, with a sense of altitude and distance. Try it with bonfire for a cabin-in-the-mountains feeling.
- Muffled Thunder
- Distant rumbles that play at adjustable intervals. On its own it's dramatic; layered with rain it becomes a cozy thunderstorm.
- Cat
- An occasional meow at intervals you choose. Mostly for fun and company. Pair it with cat purring for a quiet afternoon with a pet.
What's Inside Each Scene Preset
Presets are ready-made mixes you can start with one click. Each one uses carefully tuned volumes, and you can adjust or remove any sound after it loads.
Night
Crickets at 16%, a bonfire at 58%, and a faint chorus of frogs at 3%. The bonfire provides a warm, low foundation while the crickets add gentle texture on top, like drifting off beside a campfire on a summer night.
Kitten
Cat purring and occasional meows in equal balance. It's designed to feel like a cat curled up next to you, and it's especially popular with people who find complete silence lonely.
Thunderstorm
Steady rain at 65% with distant thunder rolling in roughly every 45 seconds. The rain does the masking, while the thunder breaks up the monotony so the mix never feels like a loop.
Primitive Forest
Forest ambience at 50% with a quiet stream at 14%. The stream is kept low so it adds movement without becoming the focus, ideal for reading or a midday reset.
Busy Square
A European plaza at 50% with extra crowd chatter at 16%. It recreates the energy of working from a café terrace, useful for creative tasks and brainstorming.
Working
Typing at 25%, soft purring at 13%, and a cat meowing about once a minute. It feels like working from home with a pet nearby: just enough activity to keep you moving.
White, Pink, or Brown Noise?
Colored noise describes how sound energy is spread across frequencies. The differences are easy to hear, and they matter for comfort.
White Noise
Equal energy at every frequency, so it sounds bright and hissy, like TV static. It has the strongest masking power, but some people find it harsh over long periods.
Pink Noise
Energy decreases as pitch rises, giving a softer, more balanced sound similar to steady rain. Research has linked pink noise to deeper slow-wave sleep, and many adults prefer it to white noise.
Brown Noise
Even more weight on low frequencies, producing a deep rumble like a waterfall or distant thunder. Popular for relaxation and with people who find other noise too sharp.
Tips for Getting the Most Out of Noisely
Keep the volume low
For sleep, aim for a level just loud enough to cover background noise, roughly a quiet conversation or less (under 50 to 60 dB). The goal is masking, not drowning everything out.
Build your mix in layers
Start with one steady base sound such as rain, air conditioner, or bonfire, then add one or two detail sounds at a lower volume. Three sounds is usually plenty.
Use the timer at night
Set a 30 to 60 minute timer so the sound stops after you fall asleep, or leave it running all night if noises tend to wake you up.
Speakers or headphones?
Speakers are more comfortable for sleep and fill the room evenly. Headphones are better for focus in shared spaces; keep the volume low to protect your hearing.
Save your favorite mixes
Once you've found a combination you like, save it from the player so you can bring it back with a single click.
Make it part of a routine
Playing the same mix every night can become a sleep cue. Over time, your brain starts to associate that sound with winding down.
