Soothing sounds for sleep are a type of pleasant sounds with appropriate frequencies that help you fall asleep easily and quickly. Let's explore the specific sounds in detail in the following article!
1. Benefits of sounds for sleep
Sounds, including white noise, can help reduce stress and anxiety while you are drifting off to sleep. If you have difficulty relaxing and unwinding your body, white noise can diminish the focus on thoughts and worries, allowing your mind to relax and prepare for a better night's sleep.
Some types of white noise, such as the sound of rain, ocean waves, a flowing stream, or gentle wind rustling through trees, create soothing and relaxing sounds. These natural sounds can create an ideal environment for relaxation and help you easily fall into a deep sleep.
2. Frequencies of sleep sounds
Different types of white noise are categorized based on frequency (Hz) and intensity (dB) and are named after colors. For example, white noise emits sound at frequencies that the human ear can hear, similar to how white light includes all colors visible to the human eye.
Some types of sleep-supporting white noise include:
2.1. White noise
White noise encompasses all frequencies in the range of 20 to 20,000 Hz that humans can hear. This type of noise has the effect of masking and blocking out any disturbing sounds from the outside, helping you easily fall asleep. Examples of sounds classified as white noise include the hum of a rotating fan, air conditioner, TV, or operating air purifier.
In addition to sleep support, some studies have shown that white noise can help reduce infant crying. However, it is important to carefully consider how to use this sound to avoid any impact on a child's development.
2.2. Pink noise
Similar to white noise, pink noise includes all frequencies that humans can hear. However, the intensity of the low-frequency components in pink noise is higher, and it includes deep sounds such as gentle rain or ocean waves. Moreover, pink noise also has the ability to mask distracting sounds like car engine noise or footsteps.
According to CNET, many people prefer pink noise over white noise due to the soothing and deep effect it provides. Some studies have even suggested that pink noise can help prolong deep sleep and improve memory by filtering out high-frequency sounds.
2.3. Brown noise
Brown noise can be considered as a deeper and lower version of pink noise, with the highest concentration of intensity in the low-frequency range. The sound of brown noise is quite strong, for example, the sound of a rushing waterfall or heavy rain with large raindrops.
Some studies have indicated that brown noise can help reduce symptoms of tinnitus and improve cognitive abilities. However, according to WebMD, more research is needed to specifically study the impact of this sound on human sleep.
2.4. Blue noise
In contrast to brown noise, blue noise concentrates the intensity of sound in higher frequency ranges with fewer low-frequency components, making it slightly more piercing than pink or white noise.
The whistling sound of a water fountain is an example of blue noise. If you are not sensitive to high-volume sounds, blue noise is suitable for masking and blocking out external sounds. Because it can be jarring when listened to at high volumes, some experts often use blue noise mixed with music to reduce noise and smooth out the sound.
3. Sounds that facilitate sleep
3.1. Sleep-inducing Rain Sound
The sound of rain is often considered relaxing and comforting to many people. Gentle rain sounds with a stable frequency can support sleep and reduce external noise. Additionally, when listening to the sound of rain, many individuals feel inclined to relax and rest in the warmth of their bed.
3.2. Sleep-friendly Natural Sound - Ocean Waves
Similar to rain, the sound of ocean waves created by droplets hitting sand and rocks is a popular choice for those struggling with insomnia or difficulty falling asleep. Ocean waves produce a sleep-inducing, soothing sound that helps calm the mind and promotes easy sleep.
According to Dr. Orfeu Buxton, a behavioral health professor at Penn State University, ocean sounds can stimulate fast sleep onset. This sound also acts as a reassuring message, conveying "Don't worry, relax!" and helps reduce stress, fatigue, and anxiety, while enhancing sleep quality.
3.3. Sleep-friendly Natural and Wilderness Sounds
Sleep aids often incorporate natural sounds from forests and mountains. These pure and simple natural sounds help relax the mind and facilitate sleep.
An experiment conducted at the University of Sussex in the UK had participants listen to recordings of natural sounds and artificial sounds to measure their nervous system activity. The results showed that natural sounds stimulated more stable brainwaves and effectively supported sleep.
Furthermore, instead of focusing on worries and tensions, these sounds help individuals imagine beautiful landscapes, evoke positive emotions, and reduce anxiety. Researchers also found that participants' nervous systems were more at ease after listening to nature recordings.
3.4. Personalized Preferred Sounds
Similar to visual and olfactory senses, sounds also have a connection with the brain and can stimulate both positive and negative emotions. To achieve a relaxed state, music or sounds that we enjoy and that match our mood are excellent choices.
3.5. Soothing Voice
Gentle sounds from warm voices, whispers, or soft music can make you feel comfortable and fall asleep. The soothing lullaby from a mother's voice during infancy is a classic example of sound through voice that provides a sense of peace and restful sleep.
You can listen to radio stations or podcasts with gentle voices and interesting stories that you love. This not only helps you have a good sleep but can also bring beautiful dreams.
However, some people prefer to sleep in complete silence, without any sound, which is known as the sound of black noise. If you frequently experience difficulty sleeping, try listening to different sleep sounds to find the most suitable rhythm for your sleep.
