Mystic Marvels LLC Genuine True-Random Analog Brown Noise Generator. Does not loop.

The BNG-200 can provide a good clean brown noise sound through your stereo system or through a set of computer speakers, which is a far better alternative than listening from "tinny" little speaker found in sound conditioners.

What is brown noise? Brown noise sounds somewhat similar to white noise, except that brown noise has a lot more bass and less "hiss" (white noise sound can sound very harsh in comparison). Technically speaking, brown noise is characterized by a 6 decibel roll-off in amplitude per octave (please see the picture gallery for spectrum analysis).

What can brown noise be used for? The gentle sound of brown noise can be used to block or reduce distractions, improve mental focus, and help promote sleep (the waterfall-like sound of brown noise can be very soothing). It is especially useful for masking unwanted low frequency noises (such as the rumble of traffic).


                                  MAIN FEATURES


  • Noise signals consist of true random impulses unlike the more
     common pseudo-random digital noise generators which
     create an algorithmic sequence of bits that eventually repeats.

  • Amplitude peaks follow natural Gaussian distribution.

  • Contains a special sophisticated filter that removes all
     frequencies that are outside the range of human hearing
     (infrasonic & ultrasonic). This eliminates unnecessary loading
     that may otherwise be imposed on your audio system.

  •  Enclosure is made from rugged high-impact ABS plastic.

  •  Product is RoHS Compliant and is constructed with lead-free 
      components and lead-free solder.

How does this product compare with other products? There are very few noise products on the market that do not repeat themselves over and over again (if your conscious mind does not pick this up, your subconscious mind will - it won't be happy). Even though the mechanical sound conditioners do not "loop" I have noticed that many of them tend to produce an unpleasant high-pitched "hollow" sound. 

Please Note: As already indicated, the noise signal produced by this device must be patched to an audio amplification system such as a home stereo system (RCA cables included) or a set of amplified speakers (such as a pair of computer speakers) to produce a brown noise sound. But don't worry, this product is very user friendly and easy to use. Hook-up is a snap.

This product is strictly powered by a wall adapter (included). Purchase also includes RCA cables (for hook-up to external audio equipment) and Owner’s manual. Unit comes with a 30 day money-back guarantee and a two year warranty. Please note that the wall adapter may vary in size and shape.

We service what we sell! These units were designed by me personally so I am fully capable of repairing them if need be. If your item gets damaged or is not performing as it should anytime after the warranty has expired, you may return it to us for repair at a very reasonable price.
