White noise and sound machines are devices designed to produce sounds that help mask background noise and create a more peaceful environment for sleep, concentration, or relaxation. Here are the key aspects of these machines:

### Types of Sounds

2. **Pink Noise**: Similar to white noise but with reduced higher frequencies, making it sound softer. Examples include rainfall or wind.
3. **Brown Noise**: Even deeper than pink noise, resembling the sound of a strong waterfall or thunder.
4. **Nature Sounds**: These include sounds like ocean waves, rain, forest ambiance, and birdsong.
5. **Ambient Sounds**: This can include city noise, fan sounds, or the hum of an air conditioner.
