Um ... Today, I drove to travel, and I suddenly got tinnitus when I went down the mountain. . . . Hearing loss after the incident

This phenomenon you are talking about is aviation otitis media, which is a kind of otitis media related to flight. Because when the plane landed, the human body moved from high to low, the external air pressure gradually increased, the eustachian tube was blocked, and the pressure in the tympanic cavity could not be adjusted in time, resulting in the imbalance of internal and external air pressure and negative pressure, which could cause leakage or bleeding in the tympanic cavity. This is secretory otitis media. This will happen not only when you are flying, but also when you are going downhill by train or car, because the height difference between the mountains where the train or car passes is very large (for example, some sections may be in areas with high altitude). With the continuous acceleration of train or car running speed, the amplitude and speed of air pressure change are very obvious, which leads to the imbalance of air pressure inside and outside the eardrum and causes otitis media. Therefore, at this time, it is best to do swallowing, chewing and other actions when the plane is descending or the train and car are driving in a big gap, which can prevent it! Generally, the situation will improve or disappear after one day. If it is still serious, I suggest you seek medical advice in time! :)
