Samenvatting:

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. A white noise machine is a device that produces a sound that is random in character, which sounds like a rushing waterfall or wind blowing through trees. Often such devices do not produce actual white noise, which has a harsh sound, but more often pink noise, whose power rolls off at higher frequencies, or other colors of noise. White Noise devices are available from numerous manufacturers in many forms, for a variety of different uses including audio testing equipment, sound masking products, to sleep aid devices, and power-nap machines. The sleep-aid and nap-machine products may also produce other soothing sounds, such as music, rain, wind, and ocean waves mixed with -- or modulated by -- white noise. White noise generators are often used by sufferers of tinnitus to mask their symptoms.
