pink noise & white noise

relaxing sounds

As the birth of his first (and only) daughter grew nigh, Daddy-To-Be Greg was faced with a problem. He had noisy dogs, lived in a small house, and liked to exercise his DIY zebrawood speakers to their fullest. After absorbing countless hours of video, birthing classes, and research - he struck upon a solution. Noise.

Not just any noise would do, of course. He needed options. Being a good little engineer, he took matters into his own hands. Firing up MATLAB, he first created some white noise (equal in amplitude across all frequencies). This sounded quite unpleasant, as our ears do not receive all frequencies equally. Applying some filtering magic, some soothing pink noise (look it up if you must know, too complicated to explain within parenthesis) was created - evoking memories of pleasant afternoons by a stream, waterfalls, and his dirty apartment in college next to I-5.

Then, the 'Eureka' moment hit. By modulating the pink noise with the white noise, he could create a sound very similar to what infants experience in the womb! The beat frequency changes over time slightly, and is very similar to a normal expectant mother's heart rate.

The result is PinkWhite. You can download this free MP3 file by clicking here and saving it onto your computer. You can then load it into your MP3 player or phone. Or you can even listen to it here online.

The result was staggeringly successful. To this day, his daughter Lillie uses this noise for naptime and bedtime. We're willing to issue a 100% money-back guarantee if these free files don't knock your infant into dreamland. They work pretty well for city-dwelling mommies and daddies, too. Parties, band practices, and maniacal dogs are all virtually undetectable with this noise in baby's room.

  - Tuning stereo and surround sound setups
  - Blocking unpleasant noise
  - Making it difficult for the CIA to hear you through that bug in your wall.
  - Insomnia-stricken city dwellers

We suggest you put these files on your mp3 player, choose the one you like, and set that player to 'repeat one.'
