Why do people become much worse to hear talks segodnya.ua

Otolaryngologists are sounding the alarm, people en masse complain of hearing loss. Furthermore, doctors are seriously talking about deaf generation. This is especially true of people who do not leave the headphones. They recorded hearing loss of at least 5-10%. Headphones subjected ears exposed stimulus strength 110 dB - greater than the take-off of aircraft. Already we can make unfavorable conclusions: one in four young people aged 16-24 years old have serious hearing problems.
A complication of otitis
Yet the constant circulation of the headphones - this is the second reason hearing loss. main and first is otitis media. It is caused by various viruses (influenza, parainfluenza, adenovirus infection) and bacteria (staphylococci, streptococci, pneumococci).
The first signs of the disease: pricking, Boring, throbbing, shooting pain in the ear. Exacerbated by the night, deprived of sleep, it gives teeth, temple and all the relevant half of the head.
In the first stage of the disease marked tinnitus, sensation of fullness, fever 38-39 ° C. In the second stage main symptom - suppuration of the ear. In the third, stops inflammation and suppuration, reduces redness of the eardrum. But significantly reduced hearing.
treatment for otitis
If time does not cure otitis media, it can become chronic and will develop complete deafness in old age. But in any case, do not try to treat yourself - to drip into the ear of alcohol or camphor oil. Such treatments can burn the eardrum and deprive a person hearing forever.
Otitis media treated with antibiotics, vasoconstrictor nose drops that the doctor prescribes. At home, make hot compress, dry warm dressing. But this is not in place the treatment, and in parallel with it.
If hearing loss, tinnitus, otitis when to pull the plug and not treated, it can cause serious complications: meningitis, thrombosis of the cerebral sinuses, abscesses of the cerebral hemispheres of the brain and cerebellum, otogenny sepsis. The most common complication - an inflammatory disease of the mastoid bone (mastoiditis). It usually develops in the second week. The process can spread outwardly, eventually destroyed bone layer develops an abscess. If conservative treatment of mastoiditis has no effect, it is necessary to do a complex operation.
Street noise - the cause of hearing loss
Noise of the streets, cars, even tapping on the keyboard - it all hits the ears. Loud external stimuli - this is the third reason hearing loss.
German scientists conducted a study and found that 48% of respondents annoyed rumble of passing trucks, another 45% - as negative view of the sound engines of passenger cars, 39% - painfully react to crack motorcycles, 25% - suffer from a drone aircraft, 21% - complains of noise at the workplace, 16% - are dissatisfied too noisy neighbors. If you add up all of these stimuli, it turns out that modern man donno and night is in stress due to external stimuli. Body perceives the first hit, is ear.
Stress due to the sounds
Loud sounds affect not only the ears, but also the entire body. For example, it is known that after smoking just noise ranks second among the causes of cardiovascular disease.
Scientists conducted the study with a group of 16 people, creating for them the current situation in the airport the night period - from 1 am to 4 am. During this time the noise was reproduced, equal to 32 takeoff and landing aircraft. The results for the six weeks the experience was different. During the first nights adrenaline and cortisol investigated jumped dramatically, then decreased slightly, and scientists have even been We tend to make optimistic conclusions that, ultimately, the human body gets used and does not respond to the noise stimulus. But after a while everything was back: adrenaline and cortisol levels rose sharply in a month more than in the beginning, and has not fallen before the end of the study.
Who is at risk
In the complex auditory system auricle plays the role of a locator. Primitive man's ears were moving and moving, like a dog: it was in fact important to determine not only the sound, but where it goes, and how close it is. The ability of living organisms to allocate the wanted signal from the noise and capture its direction is called ototopikoy. Therefore, the farther spaced sinks, the more their size, the higher the severity of hearing loss, the sooner and better they are able to recognize and highlight the various sounds. However, the sharpness of hearing deteriorates, if a person gets in an unfavorable background noise - from 80 decibels and above. They are particularly affected by such acoustic trauma gunners, construction, blacksmith, machine operators, weavers, sound engineers, musicians.
How to avoid deafness
To avoid stress and the occurrence of deafness - learn to relax and organize themselves tihoterapii sessions. Turn off everything. Even mechanical clocks, stop - Sit in a chair and relax in the silence for 15-20 minutes. Wherever you are your home, pobespokoytes to install sealed windows.
Another proven means prophylactic protection - Ear adapters or earplugs which are made of liquid silicone, taking the form of the auditory canal and reliably protecting it. They relieve the discomfort when traveling on trains and planes, "neutralize" snoring neighbor on the coupe, cherish the ears of crazy acoustic load in nightclubs and at concerts.
