In a nutshell, flowing water, nature sounds, classical music, and even steady, consistent noise like white or pink noise are often cited as effective sleep aid sounds. These sounds not only drown out unpleasant noise, but they may also relax the minds of troubled sleepers.

What Are The Best Sounds To Sleep?
The best sounds for sleep are up for debate, but your best bet for falling asleep is likely no sound at all.
In an unpublished white paper involving patients in neonatal ICUs, researchers found that higher noise levels not only elevated patients’ blood pressure and heart rates but also disrupted sleep patterns – possibly to the point of affecting development and contributing to hearing loss in premature infants.
Another study involving participants exposed to ICU noises and lights showed that those who wore earplugs and eye masks to sleep had more REM time and higher levels of melatonin (also known as the sleep hormone).
Aside from silence, however, what are the best sounds to sleep to?
Recent research shows that white noise and pink noise may help people fall asleep faster and sleep more deeply at night. “Natural sounds” like gently flowing water, bird calls, and the rustling of leaves are also believed to trigger a sense of relaxation in humans.
Below, we discuss what makes white noise, pink noise, natural sounds, and other types of sounds good sleep aids.
1. White Noise And Pink Noise
White and pink noise are often cited as two of the best noises that help you sleep.
White noise is a constant noise with no discernible pattern that contains a mixture of all sound frequencies audible to the human ear. These frequencies are all played at the same intensity. White noise sounds like radio and TV static, the whirring of a fan, or the steady hum of an air conditioner.
A study conducted by researchers at Brown University Medical School found that patients in the ICU slept better with white noise playing. According to the researchers, the presence of white noise helped dampen the perceived loudness of “peak noises” in the hospital.
Pink noise, on the other hand, consists of more low-frequency noises. This makes it sound “warmer” or “rounder” than white noise. It can be found throughout nature, such as in steady winds, the sound of raindrops, and rustling leaves.
One study showed that steady pink noise can reduce brain wave complexity, thus allowing sleepers to spend more time in deep sleep. Another study revealed that exposure to pink noise at night may improve memory.
In a nutshell, white and pink noise work as sleep aids because they are consistent and fill the bedroom with a sustained sound that is gentle enough for the brain to ignore while also muffling outside noises.

2. Oceans And Waves
The sound of waves crashing onto the shore is considered relaxing for several reasons.
For one, the rhythmic sound of waves breaking on the shore is consistent and predictable, which can create a calming and meditative effect on the brain.
Secondly, the sound of waves is a natural and soothing sound that is associated with peace and tranquility. Many people associate the beach and the ocean with positive memories, further enhancing the relaxing effect of the sound of waves.
The rhythmic crashing of waves is a popular image that mindfulness meditation practitioners use to relax the mind. Learn more about mindfulness and how it can impact sleep in our blog.
3. Woodland And Rainforest
As mentioned, studies have shown that nature sounds can be relaxing for some people. One study conducted at Brighton and Sussex Medical School revealed that natural sounds affected systems in the body that control the fight-or-flight response and the rest-digest system, a.k.a. functions that trigger alertness and relaxation.
That includes woodland and rainforest sounds such as:
- Bird songs
- Crunching and rustling leaves and twigs
- Squirrels chattering
- Crickets chirping
- Water trickling from a stream
- Frogs croaking in a pond
Researchers found that when participants listened to recordings of natural sounds, their brain activity showed more “outward-focused attention” in the brain. This is in contrast to inward-focused attention, which is associated with stress and anxiety.
4. Storms And Rainfall
While the sound of heavy rains and thunder can be anxiety-inducing for some, the sound of a gentle, steady shower could induce relaxation. After all, pink noise, which resembles steady rain and wind, can dampen sudden noises and keep people from startling awake.
5. Classical Piano Music
One study conducted at a Hungarian university found that those who listened to classical music prior to sleep reported better sleep quality.
Another study found that listening to slow music can decrease blood pressure and lower one’s heart rate, as well as improve one’s mood. Decreased blood pressure and heart rate induce a calm, relaxed state – the perfect condition for falling asleep.
Make sure to tune into songs with a slower tempo and a consistent volume, as abrupt sonic changes can be jarring and wake you up.
6. Soothing Voices
Autonomous sensory meridian response (ASMR) refers to a warm and tingling feeling that some people get when they hear certain sounds, such as crinkling wrappers, turning the pages of a book, tapping fingernails, and whispering. It’s a wildly popular genre on YouTube and TikTok where many ASMR fans go to relax and fall asleep at night.
But what is the science behind ASMR? Scientists at Dartmouth College found that those who experience ASMR showed activation in the prefrontal cortex, the part of the brain associated with self-awareness and social behaviors like grooming in primates. The researchers theorized that ASMR produces the same kind of pleasure people get from bonding and socializing.

Ways To Optimize Your Bedroom Setting For Better Sleep
Choosing the right ambient sound is just one way to make your bedroom more conducive to sleep. Other ways you can optimize your bedroom for better sleep include:
- Keeping your bedroom cool: Humans sleep better in cool rooms – keep the thermostat somewhere between 60 to 67° F.
- Keeping your bedroom dark: Your circadian rhythm, or your internal body clock, is influenced by light. Sunlight and blue light (emitted by our devices) induce wakefulness, while warm light and darkness can signal bedtime.
- Using calming colors: Your paint color of your bedroom’s can impact how you feel. Colors like blue, green, and gray can promote relaxation while red, yellow, and orange can make you feel alert and even anxious.
- Staying off your phone an hour before bedtime: Not only does your phone emit blue light, but it’s also a gateway to sleep-fighting stimulation with anxiety-inducing content and activities like games, social media, and the news.
- Reducing clutter: Clutter has been linked to high levels of stress and anxiety. The more anxious you are, the harder it is to fall asleep.
