These factors combine to produce the cumulative effect as a “white noise” our ears and then brain receive. The gentle humming and operation of the motor itself.Turbulence caused by the nearby air being disturbed due to blowing.Fan blades spinning through and disturbing the air.The rush of air on the input (suction) and output (forward) sides.Air passing by the surfaces of the fan’s body. ![]() There are several factors involved that result in that soothing noise we love: The funny thing is that fans aren’t intentionally designed to make noise! It’s a wonderful side effect of how they work. When a fan run runs, the air is drawn from the rear and forced out the front which causes noise.įans (especially traditional ones like box fans) are an easy-to-use and economical source of noise to cover sounds, reduce stress after a hard day, and promote better sleep. It’s generally caused by the air turbulence created by the blades but often contains the sound of the fan motor, too. “White noise”, the soothing sound produced by many fans, is produced by a number of things that happen when a fan is running. I speak from personal experience! How fans make white noise New environments mean new nuances and small sounds you’re not used to which can hurt your quality of sleep. You’re not accustomed to your surroundings and haven’t had time to adapt. It’s especially helpful to have a fan when you travel for many adults or children sleeping in a new environment can be tough. The result is better sleep as well as better concentration. The psycho-acoustical effect of a soothing noise causes a pleasing and focused state in both many people’s minds and bodies. For example, dishwashers, washing machines, and other sources have a pretty steady and rhythmic “pattern” that affects our brains in a pleasant way. It’s a well-known fact that infants and children are able to sleep more readily with gentle sounds. The result is that as long as the bothersome outside sounds aren’t able to exceed the white noise level we no longer hear them. This is because when many sounds are combined together well (especially with noise!) our brains can’t “hear” the distractions anymore. ![]() In reality, the fan isn’t actually removing outside sounds – but for all practical purposes, our brains think it’s gone. This means that the noise it generates simple “covers”, or masks, the sounds that cause you problems and make sleeping or concentrating more difficult. As long as the outside sound is of an equal or lesser volume than the white noise it can be blocked.įans can improve your quality of life using the principle of sound masking. Sounds you otherwise would hear are “covered” (masked) by the sound your fan generates, resulting in it effectively eliminating it. White noise helps by “masking” bothersome noise and creating a more relaxed and distraction-free environment for. “White” is used to describe this particular type while others such as brown and pink exist and describe similar noise but with different acoustical levels in certain frequency ranges. White noise is the term used to describe a sound production that’s made up of all frequencies in the audio band (the range you can hear) at equal levels. How does white noise from a fan help?
