lastknight Posted July 28, 2014 Share Posted July 28, 2014 I have and in the past been on the better side of George O BUT you are quite right others have had some pretty nasty tapes form the guy. Guess I was pretty lucky...lol..or maybe Im just choosing to forget..lol I would also rather know where I stood Instead of some of the others who say one thing and do another..and there are those . Goood thing now a days you can hold any of them to their worlds BITD not so much Remember a tape is a snapshot. You're not hearing the 4 or 5 tapes before or the nights in critique where the judge is giving advice that is possibly being ignored. I'm one of the last guys defending judges (81-83 Knights) but there is a bigger picture. Quote Link to comment Share on other sites More sharing options...

lastknight Posted July 28, 2014 Share Posted July 28, 2014 LOS and the roof..... Please remember that sound energy travels in waves...the higher the frequency the more directional they are. For whatever acoustic issues LOS has (and there are several) opening the roof will have very little effect if any. The echoes you hear during a corps performance are not coming off the roof, but at whatever surface the sound is bouncing off of. The only sound source I can think of resonating upward would be drum heads and mallet bars. Quote Link to comment Share on other sites More sharing options...
OrlandoContraAlum Posted July 28, 2014 Share Posted July 28, 2014 I can only say that if all these things are true, Crown has entertained the heck out of me this year, apparently quite by accident. Those darned meddling kids! 1 Quote Link to comment Share on other sites More sharing options...

The echoes you hear during a corps performance are not coming off the roof, but at whatever surface the sound is bouncing off of. The only sound source I can think of resonating upward would be drum heads and mallet bars. Not singling your post out, but it is the best jumping off point for a physics based discussion of why sound in Lucas Oil sucks. While what you are saying is partially true, sound is not a collimated source like a laser. Waves by nature still spread in all directions, but yes, the most intense part of the wave goes to the audience. The issue then is that the sound reverberates upwards at different times (the sound from the corps and the reflection of the sound off the stands and audience wind up out of phase). This leads to a wave effect known as interference where one wave's 'trough' hits another's 'peak.' This effectively will muddy up the sound, as some frequencies experience destruction, while others may experience construction. What this means for the audience is that you hear the initial sound, and then an echo that is slightly different, followed by another echo which is slightly different. This past paragraph is true of any enclosed performance venue, a dome or LOS. Now the question is "Why is the effect so pronounced in LOS?" The answer lies in its interior shape. A dome is more or less an ellipsoid in shape. What this means acoustically is that there are more surfaces and directions for the sound to bounce around. Now, remember that interference? That is the key as to why the echo in the GA Dome dies out more than the echo in LOS. With more surfaces, more sound waves will experience a phase shift and experience destruction. This leads to fewer sound waves making it back to you in the audience. This causes sound in the GA Dome to be more of a single echo and a light rumble as opposed to several echoes with an ongoing rumble. Continuing from this, LOS has a cylindrical roof. This is possibly one of the worst shapes for sound. Essentially, sound has three surfaces to hit: 1) the curved part of the roof (where it either gets reflected back once onto the curved part, onto the flat part of the cylinder, or back to the audience, back stands, or field); 2 and 3) the top and bottom, flat surfaces of the cylinder (where it basically is going to take a trip down the length of the cylinder). The flat surfaces are the problem. Sound travels down the length of the cylinder causes tons of little echoes which turn either into the echoes that initially escape and the audience hears or the low rumble which just seems to keep going and going in LOS. Now, the question everyone is waiting for, will opening the roof help? Yes. The sound will have a chance to escape, rather than reverberate extensively. This would give an echo more pronounced than in a bowl stadium but less pronounced than in a dome. Would people be happier? Maybe. If you are within the 30s, the difference would be night and day. Outside of that, you would only slightly more enjoy your experience (it still has room for echoes, just not to that level). In conclusion, LOS has a bad shape. This is why it sounds like drum corps in a missile silo. However, financially, this seems to be the best option for DCI: a long term contract with an enclosed stadium (practical for weather reasons, of course), so we probably will not see it moving locations anytime soon. 1 Quote Link to comment Share on other sites More sharing options...

Its a bad shape for drum corps (and other marching arts for that matter), but a logical shape for football -- its primary purpose. What DCI needs is a venue dedicated to the marching arts -- open air, football field shaped/sized, artificial turf, seating pitched just steep enough and the judging box at just the right height, with a sound absorbing canopy above to keep the rain off. Nearby will be a dedicated warm up area, that is acoustically isolated from the main field. Any other factors to consider? 1 Quote Link to comment Share on other sites More sharing options...

whitedawn Posted July 28, 2014 Share Posted July 28, 2014 And Lucas can open/close the roof in under 9 minutes. So the argument that people were killed at an outdoor fair by a freak of nature wind gust that was associated with a non-tornadic storm system doesn't hold water in an argument. Yes, it was a tragedy. But DCI and LOS officials have the capability to make decisions hours in advance of any impending weather. Let alone 9 minutes. But we've all been through these arguments before, so I'll stop right there. It isn't the 9 minutes that's the issue -- it's the several hours that it then takes to cool all the now-trapped warm air.

Isn't the solution to this simple? If there's no chance of bad weather, keep it open. If there is a chance for bad weather, close it before the competition of the day starts.
