Authentic airliner mic sound

Last night in Seattle airspace I heard a pilot broadcast that sounded exactly like a real commercial pilot- there was a specific frequency “hum”. The controller even commented that his transmissions sounded “authentic”. The pilot replied he was an actual commercial pilot and was using his headset. Question- is there a way (sound fx) to emulate this transmission sound? It sounded so cool it totally added to the immersion. Thanks, Andy.
