What is white noise?
In white noise every frequency has the same energy, from the lowest to the highest tones. The name comes from white light, which also contains all colours at once.
Because it contains so many high tones, white noise sounds bright and a little sharp. That's exactly why it works as a shield: a slamming door or a barking dog stands out less.
What do people use white noise for?
- Falling asleep somewhere noisy, like a busy street or a hotel.
- Concentrating in an open-plan office or while studying.
- Helping a baby sleep, at a low volume and at a distance.
- Distraction from ringing or buzzing in the ears. If that bothers you, talk to your doctor.
White, pink or brown noise?
Find white noise too sharp? Try pink noise, which is softer in the high tones, or brown noise, which is deeper still. All three are free in Noisely, so it's easy to compare them.
