World's Ten Most Colorful Flags. Here are ten of the most colorful flags from around the world. While it is fairly common for flags to have just three colors, like the red, white, and blue of the United States or the black, red, and gold of Germany, some flags are much more colorful than that. What makes a flag colorful tends to be a subjective decision, however.
The wind noise spectrum is dominated by the lower. frequencies (< 500 Hz), although at 27 mph when. saturation is present, the wind noise level can be greater. than 60 dB SPL at 8 kHz. It is clear that wind noise is at. high levels at commonly encountered wind speeds and. needs to be suppressed.
Pink noise, or 1/Æ, (one over frequency) is a low frequency wave-like pattern with equal energy in all octaves. a chart! (Yes that explains everything I'm sure.) Pink noise straddles the line between white noise and brown noise. White noise is entirely uncorrelated data, complete chaos, the snow on the tv screen. Brown noise is highly correlated data full of predictability. So pink noise is where the chaos of white noise and the order of brown noise meet. Some things send out the actual frequency of pink noise and some behaviors or patterns when tracked and put on a graph match up to the pattern of pink noise. I think pink noise sounds like a big waterfall. I'm listening to it right now. It's really good at drowning out the outside world, curing the ringing in your ears, or for just relaxing. Things with pink noise: wind; pulsating quasars; your heartbeat
