Brown, Pink, and White Noise for Sleep
Posted on 04 August 2009
I have a neighbor that watches television at all hours of the day and night on the other side of my bedroom wall in my condo. This experience has taught me a lesson about shared walls so if you have the opportunity to play amplified sound opposite the partition where you will be living to test the environment you most certainly should. For someone who sleeps as lightly as I do I would reccomend avoid sharing a wall. Of course, I have a friend who just bought a house and he is being nickel-and-dimed to death with all the minor maintenance so I suppose there is an up and downside to both types of home.
I can finally say that I had a decent night of sleep after using the brown noise generator at SimplyNoise.com. White noise is a sound composed of equal representation and amplification of sound frequencies across a defined range. Pink noise is an equal representation of frequencies across the band, but the amplification is proportional to the frequency resulting in higher amplification for higher frequencies. Brown noise is the opposite increasing the amplification inversely proportional to the frequency resulting in louder bass frequencies. Although white noise is a composition of equally represented frequencies the amalgamation is perceived to be higher in pitch then it really is because of the way we sense and perceive sound. Brown noise is a more pleasant neutral sound and is not unlike the faint engine noise that puts my son to sleep in the car all the time.
