![]() ![]() ![]() And “white noise,” similarly, is an even distribution of all frequencies of sound within a normal human’s range of hearing.Īs children, many of us held up a conch shell to our ear and heard the sound of the “ocean it came from.” This is one example of naturally occurring white noise. ![]() The adjective, white, comes from how we describe different kinds of light-“white light” is an even distribution of all wavelengths of light within a normal human’s range of vision. Stepping back, white noise is sound “containing many frequencies with equal intensities,” as defined by the Oxford English Dictionary. These types allow the most control and precision, as they invite their owners to gently twist them in order to fine tune the pitch of the sound-changing it from white, to pink, to brown noise, enabling the most personally soothing color or blend. With the mechanical versions, there is less sound variety, but there’s no manufactured repetition because the sounds are real, generated by the physical motor inside of the device. The digital versions offer many different soundscapes, from fan noises to ocean waves, but there’s a chance you’ll hear the loop when the recording begins again. They’re like glorified mp3 players with speakers that play pre-recorded lulling tracks. They aren’t mechanical and whirring but electronic and stationary. There’s another, newer species of sound conditioners too-the “digital” ones. The Dohm and the other sound conditioners pictured on this page can be adjusted by physically rotating the top or the side of the device to change the shape and position of the holes, which allow for more airflow and therefore sound. ![]()
