Color noises: How white, pink, and brown sounds soothe babies and aid sleep


One of the features of our Bibino baby monitoring app is the ability to play lullabies and color noises for your little one. While many people may be familiar with lullabies, color noises may be a new concept for some. Color noises are specific sounds that are believed to promote relaxation and aid in sleep. They are created by combining different frequencies of sound and are often associated with different colors, hence the name "color noises."

Color noise, also known as "white noise", "pink noise", or "brown noise", is a type of noise that is often used to help soothe babies and promote sleep. This type of noise is characterized by a balanced distribution of energy across all frequencies, making it sound similar to a gentle rainfall or a soothing stream.

Babies are particularly drawn to color noise because it mimics the sounds they hear in the womb. The constant, soothing background noise can help calm a fussy baby and promote a sense of security and comfort.

Why use color noises?

When a baby is in the womb, they are surrounded by the constant background noise of their mother's heartbeat and blood flow. This noise is known as "uterine noise". It is believed that uterine noise plays a role in the development of the baby's auditory system. After birth, a baby's auditory system is still developing, and they may find comfort in the familiar sounds of color noise.

Another benefit of using color noise for babies, especially white noise, is its ability to block out other noises that may disrupt their sleep. A baby's hearing is much more sensitive than an adult's, and even small noises can wake them up or prevent them from falling asleep. By providing consistent background noise, color noise can help to mask these other sounds and create a more peaceful sleep environment for the baby.

Types of noise

There are several types of color noise that can be used to soothe babies.

  1. White noise has a flat frequency response, meaning that all frequencies are present at equal intensity. This creates a sound that is similar to static or the hum of a fan. White noise is good for masking other sounds, managing tinnitus, inscreasing concentration and improving sleep in babies. There are many white noise machine on the market. It is best to choose one that covers as many needs as possible for you and your baby. Try the Bibino app and get a baby monitor, lullaby player and white noise app all in one.
  2. Pink noise is a type of noise that is characterized by a slightly higher energy level in the lower frequencies, making it sound similar to a soft rainfall. Pink noise is used to help babies fall asleep faster, babies sleep longer, block out disturbing sounds and improve memory. There are pink noise machines on the market. But it is unnecessary to buy a device only for such a small range of sounds. Pink noise is usually part of white noise machines.
  3. Brown noise has a higher energy level in the higher frequencies, giving it a deeper, more rumbling sound. It is similar to the sound of thunder and has a more intense sound than pink noise. Brown noise benefits are relaxation, improved focus, and of course, sleep improvement. As with pink noise, there are special brown noise devices on the market to play brown noise. But, brown noise is usually included in white noise devices.


Household appliances for creating color noises

It's important to note that while household appliances can serve as a source of white noise, they should not be used in place of a white noise machine. Many household appliances can be loud, and the noise level can vary depending on the type of appliance and how old it is. White noise machines are specifically designed to produce consistent and soothing noise, which is much more suitable for a baby's sleep environment.

While color noise can be a helpful tool for soothing babies, it should not be used as a replacement for other forms of care and attention. It should be used in conjunction with other sleep-promoting techniques, such as providing a consistent bedtime routine, creating a comfortable sleep environment, and responding to the baby's needs in a timely manner.
