The Importance of Sleep
Sleep is essential for our well-being and proper functioning. Lack of sleep can lead to reduced concentration, a weakened immune system, memory decline, and other negative effects. This highlights the importance of getting quality rest. However, many people struggle to fall asleep. Fortunately, there are solutions—one of which is white noise.
What is white noise?
White noise contains all the frequencies audible to the human ear, covering a broad spectrum of sound, also known as broadband noise. It is a repetitive or constant sound used to mask surrounding noises, either partially or completely. Its monotone flow helps the brain filter out distracting sounds, making it easier to fall asleep. Many people use white noise to improve sleep, enhance concentration, and reduce stress.
What type of white noise should you use?
There are many types of white noise, and the choice depends on personal preference.
Here are a few examples:
- A fan
- Radio or TV static
- Constant rain
- The hum of an air conditioner
- Flowing water
- A hairdryer
How to use white noise?
To start using white noise, you can buy a white noise machine, download an app, or use household items. Even something as simple as a fan can help mask background noise and improve sleep. White noise machines are widely available in stores and online, with options varying in price, sound quality, and volume control. Apps also offer both free and paid versions, allowing you to choose what suits you best.

Safety considerations
It is important to be mindful of volume levels. For safety, the sound should range between 46 and 85 decibels. To measure noise levels, you can download the NIOSH Sound Level Meter (SLM) app. However, if using a white noise app, you will need another device to check the decibel level.
