What is white noise?
White noise. People throw the term around all the time, but what exactly is it? A good thing or a bad thing? Why is it important, and why do people use it at work, at home, and for privacy?
Definition
Let’s begin with where white noise gets its name. Think about white light- white light is the combination of all the colors of the spectrum. (This is why we tell our kids “white” isn’t a color- it’s lots of colors.) Along the same lines, white noise is produced by combining 20,000 different frequencies of sound together. Stay tuned- this is important.
How it works
White noise is awesome for covering intrusive, distracting, or generally unwanted noises. By using all the sounds in the spectrum, your brain can not focus on that one irritating sound- I’m sure you can imagine something {barking dog, crying baby, neighbor noises}.
White noise works like this: think of taking a childhood road trip and sitting in the back seat. As a kid, you might remember being able to hear your parents talking in the front seat when the car is idling or going at a slow speed. As the speed picks up (on the highway for example), you can tell they’re talking, but you can’t distinguish what they’re saying unless they turn around to face you and talk louder. White noise does the same thing- assuming you don’t want to hear extra noises, it keeps your brain from focusing on it.
Applications
People use white noise in all sorts of ways:
- For relaxation at home
- For sleep
- For more productive work
- For travel
- For managing the discomfort of tinnitus
- For confidentiality and privacy
While some people use fans to simulate white noise, only white noise generators (i.e. sound machines) produce true white noise. The advantage of a sound machine is a smaller size, portability, and volume control. Additionally, most sound machines offer extra features, such as sound therapy (tinnitus), a variety of sound options (nature sounds), and even alarms and timers.
White noise is an extremely valuable resource for businesses and use at home because it reduces distractions and lets you relax so you can sleep.
