When it comes to falling asleep, there is no shortage of free soothing sounds that will help you do exactly that.
Sounds can dramatically help us fall asleep. In fact, “when a noise wakes you up in the night, it's not the noise itself that wakes you up, per se, but the sudden change or inconsistencies in noise that jar you. White noise creates a masking effect, blocking out those sudden changes that frustrate light sleepers, or people trying to fall asleep. "The simple version is that hearing still works while you're asleep," says Seth S. Horowitz, a neuroscientist and author of The Universal Sense: How Hearing Shapes the Mind.” 
We’ve compiled a list of different free soothing sounds for your nights sleep.
Calmsound is a free resource available for soothing sounds. It is categorized into 5 different categories so you can choose which sound suits you best.

Nestled in the foothills of California and back streets of Paris is the in-person Buddha Bar.
“With its cinema-style décor, covering a 1,000 square meter surface area, the Buddha-Bar boasts majestic proportions, with three levels built around a monumental Buddha, over 4 meters high. Alcove lounges wind around the mezzanine and its bar sculpted in the form of a dragon with red scales and green jade, offering strategically cozy spots, where you may enjoy a privileged moment of relaxation by candlelight, unobserved by others.”
Buddha Bar is a classic chillout bedtime soundtrack that comes right to your ears. While some of its tracks include more lounge-type music, other tracks offer pleasant jazz-time like sounds. Each track is carefully designed to mimic the feeling of the in person Buddha Bars.
The Happiness Frequency was designed to help soothe the mind, body and soul. Its brainwave sessions are suitable for adults, babies and even young adults who have trouble sleeping. Their combination of sleep hypnosis tracks and sleep meditation music will put you into a healing sleep. It combines a series of relaxing nature sounds with deep, meditative sleep patterned music so you can fall into a restful sleep.
432hZ Frequency Waves
Listening to the 432Hz frequency resonates inside our body, releases emotional blockages and expands our consciousness. “The frequency, 432 Hz, known as Verdi’s ‘A’ is an alternative tuning that is mathematically consistent with the universe. Music based on 432Hz transmits beneficial healing energy, because it is a pure tone of math fundamental to nature.” 
Its vibrations date back to early Egyptian times when all instruments are said to be tuned to this specific vibration. Within the archaic Greek Eleusenian Mysteries, Orpheus is the god of music, death and rebirth, and was the keeper of the Ambrosia and the music of transformation. His instruments were tuned at 432Hz and can supposedly help someone fall right asleep.
Reiki Sleep Meditation
The Reiki Sleep Meditation combines healing energy flows with the sound of every day nature. This soundtrack is a collection of chakra meditations for balancing & healing all the chakras (Root, Sacral, Solar Plexus, Heart, Throat, Third Eye and Crown chakra). This playlist also includes healing meditations if you prefer the sound of someone’s voice guiding you to sleep.
Tibetan Chant Music
Tibetan chant music is said to put individuals into a deep sleep because it offers us a chant/affirmation that will subdue racing thoughts that prevent deep sleep.
Some example chants include:
Saa = Infinity (totality of the Cosmos)
Taa = Life (birth of form from the Infinity)
Naa = Death (or transformation)
Maa = Rebirth
It is these sounds that directly trigger a calming sense in your brain to help with better sleep. Many Tibetan chants are repetitive, providing you with continuous sounds that rarely differ and instead, they provide the continuous sound of the universe.
If you are interested in more contemporary Tibetan chant music, check out Last.fm. Their tracks are updated weekly to bring you new soothing sounds.
Finding a track to soothe you to sleep could be your next favorite past time. It is a great way to connect with your bedtime routine to ensure you are lulling yourself to sleep every time.
