When the plane ascends, the external air pressure decreases and positive pressure is formed in the tympanic cavity. The positive pressure causes the Eustachian tube to open. At this time, you may feel a slight bulging sensation in the eardrum.
When the same plane descends, the external pressure gradually increases, forming a negative pressure in the tympanic cavity. The Eustachian tube acts like a one-way valve, and is affected by the surrounding high air pressure and is not easy to open. External air cannot enter the tympanic cavity, resulting in negative pressure in the middle ear.
Increased hearing loss, edema of the middle ear mucosa, and highly dilated blood vessels can also cause tinnitus.
Hu Yueyue knew that when tinnitus occurred, she could try chewing gum or swallowing hard to relieve the discomfort. But she did not do so because this was the method Luo Hao told her when she and Luo Hao took a plane for the first time.
And she didn't want to do anything related to Luo Hao now, so she was like self-abuse at the moment. She endured the discomfort until the plane flew smoothly, and then she slowly got better.
The end of May is not a holiday, and there are three flights a day to City D. Unless there is a delay due to special circumstances, it can reach City D in three and a half hours. So there are not many people flying today, and the economy class is even more scattered.
There were only about ten people.
Hu Yueyue was the only one sitting on the seat. She leaned back on the chair, her whole body was as weak as a boneless body, and she narrowed her eyes slightly to rest.
About an hour after the flight, Hu Yueyue's face became pale, and beads of sweat appeared on her forehead. She bent her arms to cover her stomach, where there were throbbing pains, and she even felt a little flustered.
He fumbled to unfasten his seat belt, left his seat unsteadily, covered his stomach with one hand, and walked to the bathroom in the economy class. However, when he walked there, Hu Yueyue was stunned for a moment, and then his head was covered with black lines.
Looking at the indicator light in the bathroom, it indeed showed that no one was there. However, through the gap in the bathroom that was not tightly closed, Hu Yueyue was sure that she saw someone inside, and even the white flesh was trembling -
Immediately afterwards, she heard gasping sounds, including a man's rough breathing and a woman's delicate and charming moan. At this time, a lazy and low voice with a hint of dullness came from the bathroom.
Male voice: "Are you happy? Baby?"
"Well, you are bad... uh, go deeper."
Hu Yueyue bit her lower lip. She had an impression of this female voice. She was the beautiful flight attendant who helped her fasten her seat belt. She bit her lip tightly and pressed her arms tighter to her stomach. The throbbing pain made her bow.
Get up.
However, at this time, a violent banging sound came from the bathroom, and the man's voice came again, "How is it? Is this deep enough?"
After the sound fell, a louder moan came from the bathroom, "Um...ah...uh...faster." The intermittent different tones rose with some ups and downs.
Hu Yueyue blushed after hearing this, but the throbbing pain in her stomach and panic made her unable to move. She could only lean on the door frame, frowning, the blood on her face faded, her feet were weak, and she bowed, just
When Hu Yueyue couldn't stand still.
A pair of strong arms supported Hu Yueyue's arm covering her stomach, and a pleasant, deep voice came, "What's wrong with you? What's wrong with you?"
