When I was riding a car (I was not the driver), my eardrum felt a little similar to the case when I was in a plane that was taking off, and little loss of hearing. Nothing was played inside. The feeling was gone, when I left the car. This don't happen often when I ride a car. So I wonder what might be the reason? Thanks!
That happened when the car was moving on a plain. at normal speed on a road in a city in NY. The weather was normal. I didn't sneeze. Perhaps swallowing helped a little. Windows were closed probably.
Is this not good to health?
