re: Loudest CFB Stadiums in Decibels:

The measurement of decibels can fluctuate. Let's measure Tiger Stadium excitement and the overall experience. "Changing meteorological
conditions can easily cause fluctuations in sound levels by 10-20 dB over time periods of
minutes. The longer the transmission path, the larger are the fluctuations in levels. Outdoor
sound propagation is affected by many mechanisms, including:
a) Source geometry and type (point, line, coherent, incoherent)
b) Meteorological conditions (wind and temperature variations, atmospheric turbulence)
c) Atmospheric absorption of sound
d) Terrain type and contour (ground absorption of sound, reflections)
e) Obstructions (buildings, barriers, vegetation, etc)"
