## Noise colors and recorded ambience

White, pink and brown noise are synthesized continuously. Rain, birds, thunder, ocean, forest, airport and fire use recorded loops.

### White Noise

Even across the spectrum - the broadest mask for a noisy room.

### Pink Noise

Weighted toward the low end, which most people find easier to sleep through.

### Brown Noise

Deeper still, closer to a rumble than a hiss.

### Rain

Steady and unstructured, with no pattern for the ear to follow.

### Bird

Sparse and irregular - daytime ambience rather than a mask.

### Thunder

Occasional low swells over whatever else you have layered.

### Ocean

A slow swell that rises and falls instead of holding one level.

### Forest

Leaves and distant birds, quieter than rain and less even.

### Airport

Interior ambience recorded at Tocumen airport in Panama.

### Fire

Crackle over a low bed, close-miked rather than distant.

## What a noise bed is actually for

Combine a noise color with recorded ambience and shape the result using the mixer controls.

### Sleep better, focus more

Block out snoring, traffic, office sounds, or conversations with steady color noise.

### Create your own mix

Layer white, pink or brown noise with the recorded ambience sources. Each sound has its own level.

### Runs in the browser

Start audio directly in the page, adjust the mix while it plays and stop it without downloading another app.

### Sleep timer and download

Save a mix to your account, set a sleep timer, or download a 60-second stereo WAV for offline listening. Exported mixes containing Fire include its source and license information.

## Noise Generator questions

### What is a noise generator?

A noise generator creates consistent sounds such as white noise, pink noise, brown noise, rain, or ocean ambience to mask unwanted background noise.

### What's the difference between white, pink, and brown noise?

White noise distributes frequencies evenly, pink noise emphasizes lower frequencies, and brown noise sounds deeper and heavier.

### Is Noise Generator free to play?

Noise Generator saves personal presets after sign-in, offers a sleep timer and downloads a 60-second WAV without generation credits. The seven ambience recordings need an initial download. Retain the embedded attribution when sharing a mix containing Fire.
