What about deafness? Good listening and bad listening

< P style = "color:; font family: Arial, Verdana, sans serif;" >
In your daily life, have you ever had a good or bad listening experience?

< P style = "color:; font family: Arial, Verdana, sans serif;" >
Everything was normal the first second, and then suddenly the sound around it became smaller. After a while, it seemed that it had “recovered” its hearing again?

< P style = "color:; font family: Arial, Verdana, sans serif;" >
What’s the reason for the bad and good listening? Let me analyze all kinds of possibilities for you.

Eustachian tube dysfunction

The eustachian tube is a small tube connecting the tympanic chamber of the middle ear to the back of the nose. The work of this tube is to balance the air pressure outside the ear and the tympanic chamber of the middle ear by opening and closing.

< P style = "color:; font family: Arial, Verdana, sans serif;" >
Usually we may not notice the function of eustachian tube, but when we take off and land in an airplane, you will notice it.

< P style = "color:; font family: Arial, Verdana, sans serif;" >
The eustachian tube also works harder to regulate the air pressure inside and outside the ear due to the frequent changes of air pressure when the aircraft is rising or landing.

< P style = "color:; font family: Arial, Verdana, sans serif;" >
If your eustachian tube “strikes,” your ears will feel blocked and your hearing will be affected.

< P style = "color:; font family: Arial, Verdana, sans serif;" >
The most common cause of eustachian tube dysfunction is a cold or sinus infection.

< P style = "color:; font family: Arial, Verdana, sans serif;" >
Because of the obstruction of the sinuses, the eustachian tube can not be opened normally, which leads to the pressure difference inside and outside the ear, the pressure of the tympanic membrane invagination or bulge, and the hearing is also affected.

< P style = "color:; font family: Arial, Verdana, sans serif;" >
When the symptoms disappear, your eustachian tube will open and your hearing will improve.

Fluctuating hearing loss

< P style = "color:; font family: Arial, Verdana, sans serif;" >
It is not common in general patients, but sometimes occurs in patients with Meniere’s disease.

< P style = "color:; font family: Arial, Verdana, sans serif;" >
One of the characteristics of Meniere’s disease is the fluctuation of hearing, which usually occurs in one ear.

< P style = "color:; font family: Arial, Verdana, sans serif;" >
You may notice that the hearing of the affected ear fluctuates over a period of time, which is likely to last for days rather than minutes or hours.

< P style = "color:; font family: Arial, Verdana, sans serif;" >
Exposure to high intensity noise

< P style = "color:; font family: Arial, Verdana, sans serif;" >
　　

< P style = "color:; font family: Arial, Verdana, sans serif;" >

< P style = "color:; font family: Arial, Verdana, sans serif;" >
If you are in a strong noise environment for a period of time, you may notice the temporary change of hearing, which is called temporary threshold shift (TTS), that is, the temporary change of hearing threshold.

< P style = "color:; font family: Arial, Verdana, sans serif;" >
When the human ear is exposed to loud sounds for a long time, such as concerts, gunshots or loud machine sounds, temporary threshold shift will occur.

< P style = "color:; font family: Arial, Verdana, sans serif;" >
When leaving this kind of strong noise environment, the ears will start to recover slowly, and the hearing threshold will gradually recover.

< P style = "color:; font family: Arial, Verdana, sans serif;" >
But we should pay special attention to that if we are in a strong noise environment for a long time, the temporary threshold shift can become a permanent threshold shift, that is, permanent hearing.

< P style = "color:; font family: Arial, Verdana, sans serif;" >
Cerumen embolism

< P style = "color:; font family: Arial, Verdana, sans serif;" >
　　

< P style = "color:; font family: Arial, Verdana, sans serif;" >

< P style = "color:; font family: Arial, Verdana, sans serif;" >
The accumulation of cerumen is too much, blocking the external auditory canal may also lead to “sustained” hearing loss, unless cerumen is completely removed to restore the original hearing.

< P style = "color:; font family: Arial, Verdana, sans serif;" >
But in some cases, cerumen embolism may also make your hearing better or worse:

< P style = "color:; font family: Arial, Verdana, sans serif;" >
When opening the mouth and opening the chin, such as chewing or yawning, the shape of the ear canal will change accordingly, and cerumen may also shift in the ear canal;

< P style = "color:; font family: Arial, Verdana, sans serif;" >
In the process of sound transmission in the external auditory canal, the blockage position of cerumen changes constantly, which leads to good and bad hearing.

< P style = "color:; font family: Arial, Verdana, sans serif;" >
Sum up

< P style = "color:; font family: Arial, Verdana, sans serif;" >
If you find that your hearing is abnormal, or changes from good to bad, please go to a regular hospital and have your ears examined and evaluated by a doctor or audiologist;

< P style = "color:; font family: Arial, Verdana, sans serif;" >
According to the actual situation, symptomatic treatment, such as the treatment of eustachian tube dysfunction, Meniere’s disease, away from high-intensity noise or wear anti noise earplugs, remove cerumen blocking the ear canal.
