At least one out of every three Americans doesn’t get enough sleep. The reasons for this include poor sleep habits, stress, and too much time in front of screens.

According to the Mayo Clinic, insomnia is the sleep disorder behind much of this struggle to sleep. It includes the inability to fall asleep and/or stay asleep, and can also include waking up early and not being able to fall back to sleep.

If you have ever suffered from insomnia, then you know how miserable it is to lie in bed wide awake. Using a sound machine is one easy way to help yourself sleep better.

The Science Behind White Noise

White noise is any sound where the amplitude is constant throughout the audible frequency range. This means that the sound has equal volume levels across all of the frequencies that human beings can hear. This is the type of sound most often used to enhance sleep, because it has been scientifically shown to help people fall asleep and stay asleep. White noise may also help improve sleep in those who suffer from PTSD or ADHD.

Pink noise is similar to white noise, except that has more amplitude, or volume, at the lower frequencies. It sounds like white noise with some added bass. Pink noise is common in natural sounds like waves crashing on the sand or the drum of steady rain.

This type of sound can be helpful for sleep, too. Studies have shown that people who listen to it while they sleep spend more time in deep sleep. Since that is the most refreshing stage of sleep, pink noise could help sleepers feel more rested.

White Noise for Babies

White noise doesn’t just work for adults! It also works for babies. In one study, 80% of babies between 2 and 7 days old fell asleep within 5 minutes when caretakers used white noise, as opposed to only 25% of babies who fell asleep in that same time period without the noise.

White Noise for Babies

There is some controversy over the safety of using white noise with babies. Some machines produce sound that is loud enough to damage a baby’s hearing. However, following these simple guidelines can help make the machines safe for even the smallest baby.

  • 50 decibels is the maximum volume considered safe for a neonatal nursery in a hospital. Buy a baby sleep machine that advertises volumes at this level or lower.
  • Place the white noise machine well away from the baby’s crib. Even if you can’t measure the decibel level it produces, putting it farther away from the child makes it less likely to cause damage.

Sound Machines to Help You Sleep

There are many different types of sound machines that can produce the right kind of noise to help you or your baby sleep better. These are some of the best products on the market today:
