http://lafayette-la.elaws.us/code/coor_ptii_ch34_artiv_sec34-366 Hello all, friendly neighborhood fnord, here. So, I'm trying to get my head around the Lafayette, LA noise ordinance. See the law above. What do the cops measure the DB with? I understand they have some sort of wand device. Could anyone clue me in on how they calibrate it versus ambient noise? I'd like to be able to measure for myself if I'm in compliance at any particular bar--- and go as loud as legal. hope this thread belongs here, fnord!
