About Background Noise
Background noise, also called ambient noise or white noise, is a consistent sound that masks disruptive noises and creates a soothing environment. It works by providing your brain with a neutral stimulus to focus on, helping you sleep better, concentrate during work, or relax during stressful situations. Different types of noise have different effects depending on personal preference.
Types of Noise
- White Noise · Consistent, hiss-like sound with equal power across all frequencies. Like static on a radio or a fan running. Great for sleep and blocking office noise.
- Pink Noise · Sounds like rain, wind, or rustling leaves. Lower frequencies are louder than higher frequencies, making it feel more natural and soothing.
- Brown Noise · Deep, rumbling sound like distant thunder or an air conditioner. Very low frequency, deepest of the three. Ideal for deep relaxation.
Frequently Asked Questions
Is background noise good for sleep?
Yes. Background noise masks disruptive sounds like traffic, neighbors, or pets, creating a consistent auditory environment. Many people find white or pink noise helps them fall asleep and stay asleep. Start with 50% volume and adjust to your comfort level.
Which noise type is best for focus?
This varies by person. Many find pink noise (rain-like) or brown noise (deep rumble) more natural and less distracting than white noise. White noise works well for some. Try each type at different volumes to see what helps your concentration most.
Can I mix multiple noise types?
Yes. You can turn on multiple noise types and adjust their individual volumes to create a custom mix. Use the Master Volume control to adjust the overall volume of your mix without changing individual ratios.
