Pink Noise vs. White Noise in Sound Masking

Pink Noise vs. White Noise in Sound Masking

Pink Noise vs. White Noise in Sound Masking

Feb. 24, 2023 - From white noise YouTube videos to professional sound masking solutions, there are a variety of ways to drown out or reduce noise. Noise management is a common concern in most facilities. But what is the difference between white noise and pink noise? And which is most effective in drowning out sounds, especially noise distractions, in those facilities?

What Is White Noise?

White Noise is equal power at all frequencies. That's the technical answer anyway. But in reality, it sounds like static and can be harsh, "scratchy” and uncomfortable. Despite this, white noise is a common solution to help drown out background noise, especially indirect speech, in order to improve self concentration or focus. White noise machines are very popular solutions for those looking for tools to reduce distractions or improve sleep quality.

The popularity of white, brown, and pink noise machines continues to grow. From YouTube videos to machines available on Amazon and other retailers, sound management sources continue to grow in popularity as individuals look for ways to control their environments and drown out unwanted, and unpleasant noise. Though white noise is often used to drown out sound, white noise is different from sound masking.

White noise, although the most commonly used term for the intention of its use, is not the most effective solution for noise reduction. As stated above, white noise is uncomfortable. It is necessary as white noise does cover, or mask, certain frequencies of human speech but it isn't effective in the range that it is needed. White noise only covers the very high frequencies of human speech. This is why individuals find such devices more effective as a sleep aid than as a productivity tool.

What is Pink Noise?

Similar to white noise, pink noise is equal power at all of the octaves. Again, too technical. Think of pink noise as the bass in music. It feels like the low tones or low frequencies. It is a much more comfortable experience but is less well known.

Pink noise is often used in combination with white noise in sound management solutions because it adds a layer of comfort as well as covers, or masks, the lower frequencies more effectively. This combination allows an effective sound masking system to cover a full, broadband spectrum of frequencies. Sound masking systems introduce noise into a space with the intention of covering human speech frequencies from indirect conversations – those talking about 10' to 12' away.

Pink Noise vs. White Noise: What's the Difference?

The difference between pink noise versus white noise is really in how you use them. If you are using a sound machine to improve sleep the difference is going to be in your personal preference. As mentioned above, most find white noise to be harsh but it can do the trick to drown out noises that may keep you from sleeping. Low-frequency sound, like pink noise or brown noise, tend to be more comfortable and soothing.

Which Type of Noise is Best for Sound Masking and Drowning Out Distractions?

When comparing pink and white noise for sound masking solutions, the answer to this question is a combination of both. White noise is necessary to mask certain human speech frequencies but an element of pink noise sound also covers lower frequencies as well as adds a layer of comfort. The intention behind sound masking is to cover, or mask, indirect conversations so that they are less distracting and allow you to concentrate. Sound masking is not designed to be a cone of silence. Sound masking is a noise management solution to allow the individual to achieve their best work through concentration.

With a proper sound masking system – one that combines both white and pink noise, you can create a comfortable environment and improve speech privacy. This is critical for healthcare applications, law offices, and in the general office workspace. Not only does sound masking help to reduce distractions and improve employee comfort, but sound masking improves ROI for employers.
