by Take it from a professional truck driver the holding your nose closed while trying to blow out will only pop your ears in the lower elevations after being in the higher elevation!
The only true way to get your ears to pop when you go from the lower elevation to the higher elevation. Is one let it do it naturally or two move your lower jaw like you’re a meth head while pretending to blow air out at the same time.
You should hear a series a little popping noises in your ears if you’re doing it correctly, but the only thing that really helps your ears is letting you do it naturally otherwise you’re just gonna be uncomfortable while thinking about it…..
Oh, and learn how to hawk up loogies! That helps clear your sinuses…..
