Question 1

What is the difference between white, pink, and brown noise?

Accepted Answer

White noise has equal energy at every frequency and sounds like static. Pink noise lowers the higher frequencies, so it sounds softer and fuller, like steady rain. Brown noise drops the highs further, giving a deep rumble like a waterfall — many people find it the most soothing for sleep.

Question 2

Is this white noise player really free?

Accepted Answer

Yes. It runs entirely in your browser using the Web Audio API — nothing is downloaded, there are no ads, and there is no sign-up. The sound is generated on your device.

Question 3

Is white noise safe for babies?

Accepted Answer

At a low, safe volume it can help. Keep it around 50 decibels and place the device at least 2 metres from the crib, and use it for sleep rather than around the clock. For a dedicated baby app with curated sounds and a timer, try Hushly.
