In case of long time contact with the roaring machine, noisy workshop, noisy people, etcNoise, which will cause the tiny blood vessels of the inner ear to often beSpasmodic stateThe blood supply of the inner ear is reduced, and the hearing is sharply impaired.Therefore, avoiding or reducing noise interference as far as possible is the first thing to protect hearing.
If you are always in a state of impatience and anger, it will lead toAutonomic nerveLoss of normal regulation functioninner earOrganogenesisischemia , edema and hearing impairment, which is prone to sharp hearing loss.Therefore, try to keep yourself relaxed and happy.
3. Massage
massageEarlobeWind points at the front and back (at the depression of the ear lobe and the high bone behind the ear) andAuditory acupoint(Below the front of the earscreen, chinArticular processRear edge depression), which can increase theblood circulation, has the function of hearing protection.It is advisable to massage once every morning and evening for 5-10 minutes each time. If you persist for a long time, it will be effective.Recommended: very effective earExercises。
Frequently usedEar scoopWhen a match stick is dug out of the ear, it is easy to bruise the ear canal, causing infection, inflammation and damageEardrum。It can be used when the ear is itchy and unbearableCotton swabDip a little alcohol orglycerolGently wipe the ear canal. It can also be taken orallyvitamin B, C andcod-liver oil。
When you often use MP3,mp4Or when listening to music or watching video with headphones, remember not to turn the volume too high, let alone use it for a long time, because it will reduce your hearing. If you want to use it for a long time, you can not use headphones.

In medicine, hearing loss is generally referred to asdeaf。Deafness does not mean that no sound can be heard, but there are certain differences, such as mild, moderate and severe, and evenTotal deafnessSeveral situations.Usually we divide deafness into transmission deafnessSensorineural deafnessandMixed deafnessCategory 3:
1. Acoustic deafness: refers to the hearing loss caused by the obstruction of the sound transmission and pressure transformation device, which affects the sound wave transmission.The sound transmission of human ear is mainly conducted by air, soExternal auditory meatus、Tympanic membrane、Ossicular chainThe hearing loss caused by structural changes such asAural deafnessThe main pathological changes that can cause transmission deafness are as follows:
⑴CerumenEmbolism: cerumen blocks the external auditory canal, hinders sound transmission and causes hearing loss.
⑵Perforation of tympanic membraneAfter perforation of the tympanic membrane, energy leakage occurs after sound waves are transmitted into the deep part of the external auditory canal, which leads to hearing loss.This is like a broken drum in the hammer. The sound must not be as loud as a complete drum face.
⑷Secretory otitis media: It is a non suppurative inflammatory disease in the middle ear cavityTympanumThere is fluid in it, which affects sound transmission and makes hearing loss.This is like a drum filled with water in its inner cavity, and the sound is depressed.
(6) Disruption of ossicular chain: caused by trauma and concussion of middle eardislocation of jointOr otitis media corrodes the ossicular chain, and the ossicular chain of the tympanic cavity after otitis media is adhered and fixed, resulting in soundAmplification effectReduce, affect listening.
⑺Tympanosclerosis: VariousInflammatory diseaseIt causes calcium deposition in the structure of the tympanic cavity and limited function, thus affecting sound transmission.
Transmission deafness generally does not lead to total hearing losspure toneThe listening test can find that,Air conductionhearing lossGenerally, it does not exceed 60 decibels, belonging to moderate deafness, while bone conduction hearing is basically within the normal range.
(1) Otosclerosis: unlike tympanosclerosis, otosclerosis is a disease of unknown cause.Shown as inner earOsseous labyrinthDensity ofBone plateThe disease caused by the replacement of sponge like new bone is the same as the house wall, which is made of solid bricks and concrete and replaced by sand and stone, becomes loose and weak. However, this kind of ear osteoporosis is only the first stage of the disease.Later, it will develop further. There are a lot of fibrous tissue hyperplasia and calcification in the bone, just like the cement placed in the open air. It will harden soon. This stage is also called hardening stage, so it is calledOtosclerosis。The result of ear hardening is the structural change of the inner ear,nerve cellDeformation and necrosis eventually lead to hearing loss, which is mostly bilateral and continues to worsen.Hearing loss is mostly sensorineural.
⑵ Meniere's disease: it is a disease characterized byParoxysmal vertigo、VolatilityDeafness andtinnitusThe main symptom of the disease is the sense of fullness in the ear, which is caused by the edema of the labyrinth of the inner eardrum. It is usually unilateral ear disease, which is common in young adults.
⑶ Congenital deafness: it can be caused by genetic factors, or because the mother sufferedviral infectionOr other injuries, which causes hearing loss after the birth of the fetus.
(6) Deafness caused by some other diseases of the whole body:ArteriosclerosisIs the most common.The reason is thatinner earIt is caused by the disturbance of nutrition and blood supply.Others such asdiabetes、HypothyroidismIt can also cause hearing loss.
⑼Sudden deafness: It is a sudden onset deafness disease, which may be related to the inner ear blood supply disorder and virus infection.
Can causeSensorineural deafnessThere are many reasons.According to the lesion location, the sensory sound can also beNeurogenic deafnessDivided intoSensorineural deafnessAnd neurogenic deafness.Sensorineural deafnessIt is the hearing loss caused by hair cell disease.Neurogenic deafness is the hearing loss caused by the pathological changes of auditory nerve and conduction pathway.
3. Mixed deafness: refers to the hearing loss caused by the combination of vocal and sensorial diseases.If you have chronic suppurative otitis media for a long time, you may have perforation of the tympanic membrane,Auditory ossicleThe transmission deafness caused by damage can also be caused by long-termBacterial toxinAbsorbed, caused by damage to the inner earSensorineural deafness。
1. If young people occasionally have a short tinnitus, it will soonReturn to normalThis may be caused by sudden noise stimulation to the ears, or by various reasons such as work stress, high pressure, insomnia, etc. Attention to daily life and ear use habits will ease;If tinnitus occurs for 1-2 days, you must go to the hospital for inspection.Don't think it's just tinnitus that doesn't affect your hearing, because there are some high frequenciesdeafAt first, it was just tinnitus, and the hearing was not affected, but it would suddenly appear deaf after a long time.
2. During the flight, when the aircraft takes offatmospheric pressureRapid lowering will make ears feel blocked, and a few people may also have a short timeHearing impairmentAnd pain in the ear canal.This is because when the aircraft is ascending or descendingpressureThe change ofEustachian tubeIf the middle ear tympanic cavity is under negative pressure due to pressure blockage, the human body willEar canal blockage, tinnitusAuricular distention, hearing loss and other symptoms.Therefore, it can be chewed during takeoff and landingChewing gum, as you chew and swallow,Eustachian tubeAt any timeOpening and closing, air can enter and exit the middle ear cavity freely, making the middle earInternal pressureKeep normal with external atmospheric pressureEquilibrium state, ear discomfort will be reduced or disappeared.Having a coldupper respiratory tract infectionOr people with nasal problems, it is best not to fly, so as not to cause otitis media.
3. Young parents should pay attention that children, especially infants, are prone to ear inflammation and hearing loss due to upper respiratory tract infection.Especially for newborns, do not let the baby lie flat when feeding, try to hold it sideways, otherwise it is easyChoke milkOnce choked in the ear, it is easy to breed bacteria and cause ear infection.

1、 One month after birth, the baby has relatively perfect hearing. At this stage, it is not suitable to receive large sound stimulation. Excessive stimulation may cause hearing damage. When bathing and shampooing the baby, pay attention not to let sewage flow inAuditory meatusTo preventExternal earAnd otitis media.
Attention should be paid to the correct feeding and water feeding posture, that is, to pick up the baby and takeSemi recumbent positionPosture, if the mother's milk is too sufficient and the pressure is too great, the baby's head can be slightly lowered, which can avoidChoke milkOr swallowed in timeEustachian tubecauseAcute otitis media。
2、 Otitis media is the most common cause of hearing loss.E.g. acutemiddle earInflammation is usually caused byEustachian tubeInfected, usually when catching a cold, the nasal mucosa becomes inflamed, and active bacteria will enter the middle ear directly from the opening of the eustachian tube in the nasopharynx, causing inflammation of the middle ear mucosa, especially in childhood.
Because adultsEustachian tubeNarrow, curved and long, on the contrary for infants, the eustachian tube is short and relatively thick, andhorizontal directionTherefore, bacteria in the nasal cavity and nasopharynx are easy to invade, resulting in acute otitis media or evenAcute suppurative otitis mediaIt affects listening.
Generally, the disease occurs frequently in winter and spring. It is characterized by liquid accumulation in the middle ear cavity. At present, most people believe that this disease is related toEustachian tubeDysfunction, organicimmunity, andupper respiratory tract infectionYes, some children with this disease arecoldThen suddenly appeared.
Some occur unconsciously, often withAuricular stuffiness、Hearing lossAs the main manifestation, a small number of children reported slightlyEaracheIn children, they are usually slow in listening, mislistening or inattention.
The TV volume is turned on very high, and the academic performance is reduced. Because the clinical symptoms are not typical, it is easy to be ignored by parents, resulting in hearing loss of children to varying degrees or lifelong.
3、 The middle ear is also often threatened by "neighbors", such as nasal and pharyngeal diseases, includingnasosinusitis、amygdalitis, proliferationAdenitisEtc,Regular meetingsIt is complicated with otitis media, so in order to protect the health of the middle ear, attention must also be paid to correcting this kind of disease.
There are a lot of such cases in clinictonsilAfter that, not only the chance of catching a cold is less, but also the recurrent otitis media has recovered.
4、 Many drugs have strong toxicity to the ear, which can be caused by long-term use or a large amount of use, or the patient is highly sensitive to this drughearingObstacles.
