Audiophiles Beware: Meteor Particles...
Each year the Earth receives a few inches of accumulated dust and debris from outer space...mainly meteor particles and other space dust in general. These particles go unnoticed to the human eye simply because it's such a small amount falling over some a large amount of time....each day might only receive 1/100 of a millimeter or so. Some areas are affected more than others, but generally speaking we all receive a small fraction. This fraction however has the intensity to warp the sound within your listening space. These particles are highly charged and emit just enough to make a difference. One quick method to counter these emissions is to cover your entire house or living space with aluminum foil. This might seem extreme, but then again...so is the damage from these foreign particles. Ever wonder where the fidelity went in your music? The particles have enough to take away that fidelity. Moreso, they have the ability to cause a small enough seismic force to put vibration into your system. Thus, these are probably the most detrimental part of any sound problem.
Now if you actually believe what I just wrote...shame on you. I just thought it'd be fun to write something totally crazy just to see where it would go.
