There is very little back ground noise or static, you can eliminate virtually all static with the squelch control and if you want to eliminate all the background noise an active noise reducing headset will do the trick these are expensive though and you may not even need them. . .. .Last bit of advice if you do go for a FAA medical and require a SODA (statement of demonstrated ability) "the flight test" , make sure that you get a first class medical. . .. .The reason for this is because if you get a third class medical (for private flying) and a SODA this will be noted on the SODA so your AME will only be able to renew a third class medical, if you later decide to do some flying that requires a first or second class medical then the FAA may require you to do the flight test again, usually they are pretty ok about not requiring extra testing but just in case get the first class at the beginning. Your AME will be able to renew any class of medical with a first class SODA so long as you otherwise meet the requirements.. .. .Good luck
