Noise in the ears (tinnitus). In an atmosphere of complete silence tinnitus may occur without pathology of the organ of hearing (physiological noise); it is explained by the perception of blood flow in small capillaries and vessels of the inner ear. Pathological tinnitus is observed along with the reduction of the hearing at various diseases of the outer, middle and inner ear, with neuritis of the auditory nerve, and when intoxication industrial poisons (arsenic, lead, mercury) and some medicinal substancesquinine, streptomycin, salicylic drugs). The nature of the noise in the ears may have some value in the diagnosis of diseases of the ear. The famous picture of the intensity and pitched noise in the ears can be obtained by attenuation of the noise sounds different forces and the altitude received from the audiometer. Treatment for ringing in the ears should be directed at the underlying disease of the organ of hearing.

Noise in the ears (tinnitus aurium; synonymous with ringing in the ears) is a spontaneous feeling man sounds of different height and volume. Tinnitus is divided into physiological and pathological.
Physiological tinnitus occurs in the absence of pathology of ear, if a person is in complete silence. Arising under these conditions spontaneous auditory sensation can be in the nature of sounds of different frequency and intensity.
This phenomenon is presumably explained by the following factors: 1) the biochemical processes at the level of hairy cell kortieva authority or neurons in the auditory nerve; 2) the perception of blood flow in capillaries snails; 3) the absence in conditions of silence background noise; 4) perception of motion of molecules in liquids snails.
Pathological tinnitus are divided into objective and subjective. Objective tinnitus, which would be perceived not only patients, but also other persons, in particular doctor is rare. This noise is accompanied by the decline of hearing.
Objective tinnitus may depend on muscle contractions, blood flow in vessels, movements in the joints, pressure changes in the tympanic cavity.
Subjective pathological ringing in the ears, feel only by the patient, is the most common form of ear noise. It can be permanent or temporary, simple or complex, intense or weak, in one ear or both ears, and so on, noise in the ears can be combined with hearing loss, and may be the only symptom of the disease. Tinnitus may depend on pathological changes in the external (foreign body), average (Qatar auditory tube, adhesive otitis media, tympanosclerosis, otoscleros or inner ear (dropsy of the maze, Meniere's disease, and so on). One of the frequent causes of tinnitus is an intoxication of different pharmacological agents such as quinine, cocaine, salicylates, barbiturates, antibiotics, drugs containing arsenic, mercury and other toxic substances. Professional factors in causing tinnitus most important intoxication aniline arsenic, mercury, coal gas, carbon monoxide, phosphorus, lead. Tinnitus may occur during acute or chronic infections: influenza, pneumonia, diphtheria, mumps, typhoid, malaria and others In the diagnosis of subjective tinnitus is essential history. The idea of the tone of tinnitus can provide research based on the silencing noise in the ears pure tones or noise of a certain frequency spectrum and intensity obtained from the audiometer.
Treatment of tinnitus is a very difficult task. There are General and topical treatment, the influence of physical factors, psychotherapy. When expressed tinnitus used surgical treatment.
