In addition to the question about "need" of the instrument rating (as for my current hours I will not need to pay due to flight instructing), I would like to ask you if you can let me know whether there are active noise cancellation headphones being used by some of the pilots or even if they are given out by the companies?
I do like to protect my hearing, but on the other hand it may get more complicated if my passengers would need something of if the engine would start to run roughly etc.
Thanks for the advice
