While some sounds like dog barking can disrupt your sleep, white noise helps to calm your brain down. White noise blocks out all other sound disruptions and relaxes your brains.

If your cat or dog is afraid of loud sounds, you might use a noise machine to soothe them. For example, if your pet fears thunderstorms or renovation sounds next door, use a white noise machine to calm them down.

Types of Noise for Sleep

Types of Noise for Sleep

If you have noisy neighbors or wake up when your partner comes home late when you sleep, a noise machine can be the right option for you. Most of the devices use brown, white, or pink noise. They have the same principle but are a bit different to fit all sleepers.

Pink Noise

This kind of noise has all the frequencies the human can hear. Still, it is not as loud as the original white noise, because the energy of frequencies distributes unequally across them. Pink noise is at lower frequencies and is more intense, so it creates a deeper sound.

Pink Noise

There are many natural sources of pink noise, such as wind, steady rain, heartbeats, and rustling leaves. The human ear perceives pink noise as “even” or “flat.” Pink noise has powerful potential as a sleep aid because it reduces brain waves and increases the stability of sleep. It supports memory and helps you feel better in the morning.

White noise

White noise

White noise includes all the frequencies a human ear can hear. Still, these frequencies have even distribution, so it is more intense than other types of noise. It creates a humming sound, like radio and television static, whirring fan, humming air conditioner, or hissing radiator. It also has the potential to mask sounds that can stimulate your brain and disrupt your sleep. People with insomnia can benefit from such noise, and it can help people with sleep disorders and difficulties.

Brown noise

red noise

This type is also called “red noise.” It has higher energy and lower frequencies, so it’s deeper than white and pink noise. Brown noise in nature is thunder, strong waterfalls, and roaring. These sounds are similar to the human ear. There is no scientific data on brown noise for sleep, but many people successfully use brown noise machines for sleep and relaxation.
