Where did you get your table? Several of the groupings seem off to me. Loud voice should be higher, 40 dbSPL should be nighttime home, etc. Also, were the readings specified as “A” weighted or “C” weighted?
DC got incredibly loud due to the metal bleachers and the kids stomping repeatedly on them. It sounded like an approaching storm.
It was really quite impressive.
I expect FLR to be quite loud with 49 teams wedged into the Gordon Fieldhouse and it’s designed for spirit (large floor space for teams to basically come down to and get their spirit thang going).
As for standing next to the speakers I was next to the speakers alll weekend in DC. The sound in that opening video actually vibrates through you and I swear it’s displaced something internal.
Oh darn… I completely forgot about the metal bleachers in CT.
Between that & the Oink Oink Boom team coming this year & the rest of the already loud CT/MA/NY teams attending…
Aye… I should have gone and voted higher than I did & should have chosen the "Standing next to a jet on takeoff " option! :eek:
jersey was really loud… for most of the last two days, i had to shout to talk to someone in the row in front of me… also, the DRP was one of the loudest things i have ever heard… we had all these crazy chants going on… the weird thing was, we were rooting more for some other peoples’s teams than they were…
Readings showing high levels of foot stomp are almost certainly “C” weighted. “A” weighting simulates the Fletcher-Munson human sensitivity curves which compensates for the reduced sensitivity to low frequencies and slightly reduced highs. I have modified your table with stated levels from a table in the Audio Engineering Handbook by K. Blair Benson from McGraw Hill. It includes OSHA industrial exposure limits but is by no means a comprehensive list.
NJ was definitely a lot less loud than in previous years, specifically from the A/V system. The crowd was kinda loud, to the point of interrupting conversations and causing pain to the ears. Someone even had an amplified megaphone…
I only wanted to have earplugs for maybe 30 minutes, rather than almost the entire weekend.
I am sorry but that was poorly thought out, multiple times another programmer and myself would have to leave the building and program outside. The good news is I don’t think there are metal bleachers at Key Arena.
I have a feeling that our robot will be making up for the drop in noise from the stands.
Our shooter takes care our the higher pitch sound, while the conveyor belts take care of the low growl… It is part beast.
It is acceptable to ask the staff there to see if they can turn it down a bit? Team spirit and energy is nice, but in any case, health should be evaluated first. My regional is week six. I don’t want to ruin the fun for people but this would really be a health concern…
This should definitely be acceptable if you find that the volume is too loud. From what I remember I don’t think it was all that bad last year at MN (in Williams where 10,000 Lakes is). If you are really concerned about it you may want to send Regional Planning Committee Chair Mark Lawrence an email before the event to make sure it gets addressed with the DJ and A/V crew. If you don’t have his email drop me a PM and I’ll get it to you.
At San Diego, I had to tell one of the safety advisers that people were going to get permanent hearing damage if the volume of the pit speakers was not reduced. They were placed approximately 15 feet from pit areas, directly adjacent to a main aisleway, and at a volume so loud that I saw several people cover their ears and duck/dodge away any time something was announced over them. Holding any sort of conversation 20 feet away from these speakers was impossible while their was audio on them. I was also concerned for the safety of all the judges sitting directly in front of the cheering section. A hundred screaming kids can pack quite a punch on the eardrums.
I will note that the music, MC, and match announcer levels seemed fine.
