What is Pink Noise?

Pink noise is a constant sound in an environment that helps filter out distracting noise. Think of rustling leaves, waves crashing, or steady rain. This noise is an audible sound with amplified lower frequencies and a reduced higher frequency.  It consists of several frequencies with an equal amount of energy.  

Pink noise is unique because of its consistent frequency, which it uses to create a flat and even sound. Pink noise has a high bass compared to other noise like white noise. Frequently, sound engineers use pink noise to equalize auditoriums. They set a real-time analyzer that can display the frequency of pink noise in an arena.

Is Pink Noise good for sleep?

Some noise sleeping aids help induce sounds while sleeping and help to ease the brain and promote better sleep. Noises can affect how well we rest because our brain continues to process sounds even as we sleep. Noises like barking dogs, industrial noise, and cars honking due to traffic can stimulate the brain and disrupt sleep. 

There are various sleeping-inducing sounds on a sleep machine, computer, and smartphone. Pink noise is a constant background sound that helps to increase sleep stability and reduce brain waves. Pink noise is deeper than white noise because it has a lower frequency. One benefit of pink noise is its ability to support memory and make people feel better when awake. 

Many people have noise preferences when it comes to sleep. However, to enjoy using the pink noise, you need to know your choice. Some people are comfortable using headphones instead of earbuds to listen to pink noise. Experiment with volume to figure out your sound-level preference.

Pink noise is the soothing and gentle background hum, which helps to filter out distracting sounds. It is also known as Ambient Noise. 

What is Pink Noise Used For?

Many people use pink voices for various reasons, such as to treat hearing conditions like hyperacusis and tinnitus. If you have stress, anxiety, and toss around at night, experiment with sounds such as pink noise. Pink noise helps to distract people from noises that interrupt sleep. When we listen to pink noises, it sounds even, flat and soothing to the ear, leading to a sound sleep.

Examples of Pink Noise 

Several natural sounds are pink noise. However, it is essential to note that not all natural sounds are pink noise.  Some pink noises are:

• A rushing river
• Heartbeats
• Rustling trees or plants
• A steady and gentle rain
• Ocean waves

Different Colors of Noise

There are various types and colors of noise in the world. All the colors of noise have different significant properties and how they sound to the ears. Some of these colors are:

1. White Noise: This is a spectrum of noise with all the frequencies of an equal measure of audible sound. The frequencies are audible to the human ears. It is measured in decibels, and its frequency is between 20 hertz to 20,000 hertz. The noise is good for masking environmental noises disrupting sleep. Some examples of white noise are:

• A television static
• Hairdryer
• A humming air conditioner
• Dishwasher
• Clothes dryer
• A whirring fan

2. Black Noise: A black noise is also known as a lack of noise. Black noise is when there is complete silence with little random noise. It might be hard to find a tranquil environment; however, it helps sleep at night. The dominant energy level of the black noise is at zero all through the frequencies.
3. Brown Noise: This color of noise also helps with a good night’s sleep; however, it also helps with concentration. People listen to brown noise to drown out distractions while reading and improving working productivity. The brown noise has a deeper sound than the white and pink noise. Some examples of brown noise are:

• The sound of a strong waterfall
• Low roaring
• Thunder

4. Blue Noise: The frequency of this noise is proportional to its spectral density. This noise has no bass sounds; instead, it is all treble sounds. Blue noise is not used for sleep because it has amplified high-pitch frequencies. This noise is also known as Azure Noise. An example of a blue noise is the hissing sound of water spray.
5. Gray Noise: This noise is slightly like pink noise; however, the sound is very different and distinct to the human ears. Doctors use this sound to treat ear conditions and test a person’s hearing. This noise has more power at both the bottom and the top frequency of the spectrum.

Final Thoughts 

There are several colors of noise; however, the most common one is the Pink Noise. Doctors use pink noise to treat ear conditions like tinnitus and hyperacusis. It helps to induce brain waves and increase sleep stability. Pink noise uses its consistent frequency to create a flat and even sound.
