What is a white noise machine?
White noise machines are devices that create artificial noise sound with a white noise pattern in order to mask distracting or bothersome outside noises. This can improve sleep, focus for work or study, provide privacy in doctor and patient situations, and promote a general feeling of lower stress.
While “white noise” is generally the most common type of noise in use. However additional options such as fans, nature sounds, and other noise patterns are featured on some models.
Many white noise generate sound using a small loudspeaker and digital components, although some models use an electromechanical design such as a fan and enclosure to produce a similar effect.
