Genuine True-random Analog White Pink Brown Noise Generator

Be sure to check out our other listings. We also offer stand-alone white and brown noise units (less expensive). The PNG-400 Analog Signal Noise Generator can provide good clean white, pink, or brown noise through your stereo system or computer speakers, which is a far better alternative than listening to white or pink noise from a "tinny" little speaker found in sound conditioners. Not only that, but most sound conditioners just repeat the same sound over and over again (if your conscious mind does not pick this up, your subconscious mind will - it won't be happy). The noise signals that are produced by the PNG-400 consist of true random impulses that will never repeat. What about mechanical sound conditioners? Well they tend to produce a high pitched "hollow" sound which is not pleasant to listen to. What can white noise be used for? White noise sounds similar to rain and 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. What can pink noise be used for? Pink noise sounds similar to a waterfall and can help promote a state of relaxation & sleep for both babies and those suffering from insomnia. Pink noise can also provide relief for those suffering from tinnitus. I have found pink noise to be especially helpful at masking distracting noises (like your neighbor's barking dog), which can help improve focus and concentration. Some people even use pink noise as an aid for meditation practices. Other uses include testing and calibrating sound systems. The pink noise signal is accurate to within plus or minus 1/2 decibel (see picture gallery for spectral analysis). What can brown noise be used for? Brown noise is rich in bass and resembles the roar of a very large waterfall. Just as with pink noise, brown noise is most commonly used for masking unwanted noise (especially useful for masking the low frequency rumble of heavy traffic). The gentle sound of brown noise can be especially soothing. Please see the picture gallery for spectrum analysis of white, pink, and brown noise. 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 pink noise sound. But don't worry, this product is very user friendly and easy to use. Hook-up is a snap (see photo gallery). 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. Note: Since the same signal is delivered to both output channels, the resulting sound will be in mono. Therefore, if you desire true stereo sound (stereo sounds richer and fuller than mono - the difference is incredible) two units are required. For stereo operation, you simply plug an RCA cable into each unit and then connect only one RCA plug from each cable (does not matter which ones - left or right channel) into your stereo system, leaving two plugs unconnected.
