I wanna say anything above 90 decibels is when they wont let you in. Keep in mind they dont always do that test. If you go on a holiday, there is more of a chance they will, if you go on a monday regular week day, there wont even be anybody at the gate most likely. I went with Shearers pipes last year and never got checked, only for screens and I had some rigged in there. Im going with SLPs this season and they will pass if i get tested. Just make sure you got your screens thats the most important part.
