Best fan noise machine9/7/2023 ![]() To our ears this appears as a mixed “white noise” effect that’s rhythmic, calming, and helpful for blocking many of the sources of sound that make studying, relaxing, sleeping, and life in general much harder.īecause of their design, they tend to vibrate a bit which also lends itself to affecting their sound output as well. Air forced out of the front side which blows forcefully in the room.The fan blade noise due to rapidly turning and moving air.The electric motor’s vibration and hum it produces.The rush of air on the input (suction) side.I say that because they’re not designed to do so…it’s a by-product of how they work.īox fans have several factors and sources of noise that combine to result in a soothing white noise: ![]() The movement of air from the input (suction) side of the fan, the fan motor itself, the air disturbances at the blades, and the air blowing from the front side combine to mask outside distractions.īox fans are accidentally good producers of white noise. How box fans make white noiseīox fans create noise from a combination of sources that result in a soothing and calming noise. However, that’s just a trivial detail to know. Note: Technically speaking, box fans actually don’t produce white noise but produce “brown noise.” People tend to use the term “white noise” interchangeably with brown noise which is similar but different in how the upper range of frequencies is produced. Since your brain will never hear them (as long as they’re not louder than the white noise) it’s like they don’t exist! After a certain point, it’s impossible to pick apart the individual instruments and so on. There’s simply too much information to process, and when sounds become combined together they can’t be separated.įor example, try listening to 2 or 3 music sources at once. The human brain can’t pick out separate noises when there are many mixed together. Box fans effectively eliminate troublesome sources of sound by keeping our brains from being able to detect and react to them. However, to our brain, it’s as if they don’t even exist at all. That simply means the noise a fan produces covers up – or “masks” – those distracting outside sounds. The noise produced by a box fan doesn’t actually remove sounds that bother you – they help by a process called masking. When sounds are covered up sufficiently, your brain doesn’t process them or spend any time being distracted by them. This simply means they cover up audio that is equal to or below the volume of the noise generated by a box fan. Just about anywhere you need relief from distractions white noise is extremely helpful.īox sounds produce white noise that works to block out bothersome sounds by what’s called masking. People who have difficulty sleeping while traveling (like me) often carry a small white noise machine to help. It’s often used in places like baby nurseries, hotel rooms, therapy offices, and of course bedrooms. People respond well naturally to soothing sounds like it and other sources of pleasing audio, so it can also help you relax and enter a lower-stress and more focused state, too. White noise is very different from music because it’s intended to cover the entire audio range of human hearing (about 20 Hertz to 20 Kilohertz).īy contrast, music for example only has portions of sound from a singer, synthesizers, and so on that occur in a few areas of the range your ears can hear. ![]() Many of the sounds you hear every day and that would distract you occur in a few portions of the range of human hearing. It is used to mask – or cover up and block – bothersome sounds. Technically speaking, white noise is a range of noise audio that covers the full range of sound frequencies your ears can hear. White noise is an interesting topic! Of course, we’re most concerned about how it can give us relief for lots of problems caused by distracting outside sounds. This is very important as I’ll explain later. The term “white noise” describes a sound source that produces audio noise throughout the entire range of human hearing.
