Looking for a white noise machine online to order or just trying to find white noise to listen to so you can get to sleep? This type of noise is all-encompassing just like white light, which is made up of all the colors of the rainbow that humans can see. White noise is composed of all sound frequencies that can be picked up by humans, ranging from 20 hertz to 20,000 hertz, with every frequency equally distributed. Due to these particular characteristics, white noise has the ability to mask other sounds and is perceived as “static” by the human ear. These attributes make white noise the perfect background companion for many activities such as studying, sleeping, and completing tasks that require concentration.
Scientists are just beginning to understand the complex connections between sound and cognitive function. When it comes to selecting the best type of noise for your activities, personal preferences should always be considered. Shopping around for a white noise machine online or streaming sleep-promoting sounds is easier than ever, but let’s get more technologically advanced and go way beyond just standard white noise.
Endel, a recently released iOS mobile app now available worldwide, was developed by a Berlin-based team of artists, developers, and scientists who understand the connection between sound and our well-being in terms of our heart rate, blood pressure, and state of mind. Users are given the option to select from four different sound modes based on their personal needs— Focus, Relax, Sleep, and On-the-Go. The app then automatically generates a distinct natural soundscape, which also adapts real-time to a number of personalized inputs such as location, time zone, weather, and heart rate. Test it out for yourself by downloading Endel here or via the button below.

Multiple scientific studies indicate that certain types of music and sounds, such as those featured above, have the power to help lull us into a deep sleep. Sounds inspired by nature, devoid of instrumentation or human vocals, have been shown to be equally or even more effective than traditionally composed melodies.
