Everyone knows that the 12th Man in Seattle maybe a large helpful friend, However, Sound and Rain together could actually turn this 12th man into nothing. The game has a high chance of 90% rain, and as long as we hold onto the ball, a little bit of rain can be the Saints 12th Man. Being a biologist, and studying physics in college. I remembered this, sort of..So I did a little research to help explain what I remember. I would like to tell you a little story about Refraction, and how it can help when water( rain is involved): Refraction of waves involves a change in the direction of waves as they pass from one medium to another. Refraction, or bending of the path of the waves, is accompanied by a change in speed and wavelength of the waves. So if the media (or its properties) are changed, the speed of the wave is changed. Thus, waves passing from one medium to another will undergo refraction. Refraction of sound waves is most evident in situations in which the sound wave passes through a medium with gradually varying properties. For example, sound waves are known to refract when traveling over water. Even though the sound wave is not exactly changing media, it is traveling through a medium with varying properties; thus, the wave will encounter refraction and change its direction. Since water has a moderating affect upon the temperature of air, the air directly above the water tends to be cooler than the air far above the water. Sound waves travel slower in cooler air than they do in warmer air.( It’s going to be in the 40s) For this reason, the portion of the wavefront directly above the water is slowed down, while the portion of the wavefronts far above the water speeds ahead. Subsequently, the direction of the wave changes, refracting downwards towards the water. Seattle’s 12th man may not be such a problem, its combined in narrow stadium, with rain, and cold temperatures. Therefor, the water will send the sound all over the Stadium, not just down at our boys on the field. Seattle fans can scream all they want, but the sound could actually bounce back at them or even just bounce off the walls and out of the top of the stadium itself. Yes, it will still be loud, but for what it’s worth. They will not break the noise barrier that they so hopefully want. In fact it may just shoot them in the foot.
