Hey, I can't remember. I know I had someone that was a cleaner for norther already in mine, don't know if you were in that one. Have you had your medical yet? As I am trying to find out about the hearing test levels for a conductor.
I know for a driver your hearing loss can not exceed 40 decibels, but can not find anything for a conductor.
Just went for a hearing test in boots and the maximum hearing loss I have is 25 decibels.
