What is the Noise Generator?
Your personal sound machine for focus and calm
The noise generator is an online tool that plays continuous white noise, brown noise, pink noise, and ambient noise. It works as a digital sound machine to mask distractions anywhere.
White Noise
Produces pure white noise that covers all frequencies equally for total sound masking.
Brown Noise
Deep brown noise with strong low-frequency rumble for sleep and relaxation throughout the night.
Pink Noise
Balanced pink noise — softer than white noise, ideal for gentle background noise all day.
Ambient Noise Mixes
Combine rain, wind, and ambient noise layers for custom soundscapes tailored to your needs.
Volume & Tone Control
Adjust volume and frequency balance to shape your perfect background noise profile.
Timer Function
Set a sleep timer so your sound machine fades out automatically at the right moment.
