re: Going to NASCAR race later this month - best noise cancelling headphones to use

There is a hauler on the merch hauler row that rents headphones and scanners.. The scanners are already programed with all the drivers frequencies. They have the option to get ones with or without the microphone. It takes a while to put all frequencies into a scanner so I recommend this unless you just want to program in a couple into the one you have. Noise cancelling headphones won't work for a NASCAR race. You'll need the real headphones with the earpieces that cover your ears.
