+# Noise
+
+<DocsDemo>
+  <NoiseDemo />
+</DocsDemo>
+
+Noise is an effect that adds Gaussian noise to the scene. This can be used to simulate a variety of effects, such as static on a TV or film grain.
+
+## Usage
+
+```vue
+<script setup lang="ts">
+import { BlendFunction } from 'postprocessing'
+
+import { EffectComposer, Bloom } from '@tresjs/post-processing'
+</script>
+
+<template>
+  <EffectComposer>
+    <Noise
+      premultiply
+      :blend-function="BlendFunction.SCREEN"
+    />
+  </EffectComposer>
+</template>
+```
+
+## Props
+
+| Prop                 | Description                                                                                          | Default                                                                                                                                        |
+| -------------------- | ---------------------------------------------------------------------------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------- |
+| `blendFunction`      | The blend function of this effect. This prop is not reactive.                                        |  [BlendFunction.SCREEN](https://github.com/pmndrs/postprocessing/blob/c3ce388be247916437a314f17748a75329d65df1/src/enums/BlendFunction.js#L40) |
+| `premultiply`          | Indicates whether noise will be multiplied with the input colors prior to blending | `false`           |
