What can white noise be used for? White noise can be used to block or reduce distractions to help improve mental focus. It is great for masking unwanted high frequency noises (like children playing/laughing). White noise can also be used as a sound curtain to aid in preventing eavesdropping on private conversations. True-random white noise can also be utilized for some computer applications such as cryptography, or even for paranormal research. Click here to learn more about white noise.
