Measure the decibels at MSU during a few games. Find the highest level and then if noise is really the problems then have the LSU's, Ala, Fla's reduce their crowd amount until the decibel levels approaches/equals that at MSU with the cowbells going.
A decibel meter only measures sound. It does not discriminate between artificial noise (what ever the hell that is) and real noise. If the level of "noise" is truly the concern by our esteem partners in the SEC then they should be willing (they should be eager) to adjust their noise levels accordingly and reducing crowd size.
Actually, I do agree. Take them to court. Have a judge demand that all schools have approximately the same level of noise. Reducing crowd sized at Fla, LSU, Tenn etc. would be the only solution. The only fair solution.
