Is white noise safe for sleeping?

Yes, at a moderate volume. Keep the level no louder than a soft shower and position speakers or headphones at a comfortable distance. Prolonged exposure to very loud noise can affect hearing.

Does the noise use a lot of data or CPU?

No. The noise is generated locally using the Web Audio API, so it uses minimal CPU and zero network data. It will not slow down your device.

Can I run the noise generator in the background?

Yes. The generator continues to play when you switch to another browser tab or minimize the window, so you can work or study while listening.

Types of Noise Explained

White noise: Equal energy across all frequencies. Sounds like static or a fan. Great for masking sudden sounds.
Pink noise: Energy decreases at higher frequencies. Sounds fuller and more natural, like steady rain.
Brown noise: Even more energy in low frequencies. Deep, rumbling sound similar to a waterfall or heavy wind.

How to Use the Noise Generator

Open the Noise Generator

Navigate to the Noise Generator tool on Toolin.

Select a noise type

Choose between white, pink, or brown noise depending on your goal.

Adjust the volume

Set the volume to a comfortable level. Noise should blend into the background, not overpower your environment.

Press Play

Click Play to start generating noise. The audio runs continuously until you stop it.

When to Use Each Noise Type

White noise is ideal for blocking out sharp, unpredictable sounds like traffic or office chatter. Pink noise is preferred for sleep because its softer high-end is less fatiguing over long periods. Brown noise is favored by people who find deeper, rumbly tones more soothing and is popular for meditation and deep focus sessions.

Best Practices

Keep the volume at a moderate level to protect your hearing during extended listening.
Use headphones for the most effective noise masking.
Experiment with all three types to discover which one works best for you.
Combine noise with a timer if you want it to stop automatically after a set period.
