Understanding Noise Types
• White Noise
Think of it like the sound of a fan or TV static. It has equal power across all frequencies, which makes it great for drowning out other sounds. Many people use it to help them focus at work or sleep better at night.
• Pink Noise
This sounds more natural than white noise - like gentle rain or rustling leaves. It has more power in the lower frequencies, which makes it warmer and less harsh on your ears. It's become really popular for sleep because it feels more soothing.
• Brown Noise
Also called red noise, this has a deep, rumbling quality - like distant thunder or ocean waves. It emphasizes the low frequencies even more than pink noise. People who find white noise too sharp often prefer brown noise for relaxation.
• Blue Noise
This is the opposite of brown noise - it emphasizes higher frequencies, creating a bright, hissing sound. It's not commonly used for relaxation but can be helpful for certain types of audio testing or when you need to mask low-frequency sounds.
• Violet Noise
The most intense of the colored noises, with very high frequencies dominating. It creates a sharp, almost piercing sound that's mainly used by audio engineers for equipment testing. Most people won't find this pleasant for everyday listening.
Which One Should You Choose?
For sleep and relaxation, try pink or brown noise first - they're gentler on your ears. If you need to block out conversations or focus while working, white noise is your best bet. Blue and violet noise are really just for technical stuff, so most people can skip those unless you're doing audio work.
