How noise generators are used

• Psychiatrist offices often use white noise generators to maintain the privacy of their patients. Some people use white noise to help block out irritating background noises that prevent them from sleeping. Other uses for white noise include masking tinnitus, blocking distractions, soothing migraines and configuring audio equipment.
  
  

How they work

• Many white noise generators play a recorded sound and loop the sound repeatedly. The sound lasts a few seconds in length. Some generators put forth a sound continuously. Others generators emit a continuous signal. Each manufacturer uses its own details.
  
  

Computer applications

• Linux users can download an application that lets their computer acts as a white noise generator. Windows and Macintosh users can download similar programs.
  
  

Motors?

Price range

• Consumers can purchase white noise generators from a little less than $60 to a little over $300.
