Hearing test

When clarifying the patient’s complaints, attention is drawn to hearing loss in one or both ears (constant, progressive, or with periodic improvement, worsening), degree of hearing loss (hears conversation at a short distance, communication with others is difficult at work, at home or at home, is used constantly, periodically by the hearing aid, how it affects hearing acuity, changes in hearing in a noisy environment and during excitement), subjective tinnitus (periodic, almost constant, constant painful, progressing to one or both ears, with which the patient compares noise and fatigue from it), the presence of autophony, sensation of iridescent fluid in the ear.


From the anamnesis, the duration of hearing loss and tinnitus, changes in hearing and the nature of noise in the dynamics of the disease, causes of hearing loss, concomitant diseases affecting hearing (cardiovascular diseases, kidney diseases, osteochondrosis of the cervical spine, etc.), age-related hearing changes, applied conservative and surgical treatment for hearing loss and its results.

Hearing test

  1. STUDY OF HEARING
    The main objective of hearing research is to determine the acuity of hearing, i.e., the sensitivity of the ear to sounds of different frequencies. Since the sensitivity of the ear is determined by the threshold of hearing for a given frequency, in practice, the study of hearing consists mainly in determining thresholds of perception for sounds of different
  2. Researching forks with tuning forks
    A more accurate method is the study of hearing using tuning forks. Tuning forks emit pure tones, with the pitch (oscillation frequency) for each tuning fork being constant. In practice, tuning forks tuned to tone C (do) in different octaves are usually used, including tuning forks C ,, C, c, cv c2, c3, c4, c5. Hearing tests are usually performed by three (C128, C512, C2048 or C4096) or even two
  3. Speech Research
    The simplest and most affordable method is the study of hearing by speech. The advantages of this method are that there is no need for special instruments and equipment, as well as in its correspondence to the main role of the auditory function in humans - to serve as a means of verbal communication. In the study of hearing, speech uses whispering and loud speech. Of course, both of these concepts do not include the exact
  4. Hearing examination with an audiometer
    A more advanced method is the study of hearing using a modern apparatus - an audiometer (Fig. 20). {foto22} Fig. 20. Researching hearing with an audiometer An audiometer is a generator of variable electrical voltages, which with the help of a telephone are converted into sound vibrations. For the study of auditory sensitivity in air and bone
  5. Speech Research
    The distance at which the subject perceives whispering and colloquial speech serves as an indicator of visual acuity. Normally, in a whispering speech, a person hears low sounds at a distance of at least 6 m, and high ones - 20 m. The room where the study is carried out should be quiet. In a hospital, a hearing test can be performed in the patient’s room. Every doctor produces a constant whisper intensity
  6. Study of hearing in children
    The study of hearing in children should be preceded by a collection of brief anamnestic information: the course of the child’s early physical development, speech development, the time and causes of hearing loss, the nature of speech loss (simultaneously with deafness or after some time, immediately or gradually), the conditions for raising the child. In various periods of a child’s life, the occurrence of hearing loss and deafness is associated
  7. PHYSIOLOGY AND METHODS OF STUDY OF HEARING
    The auditory system provides a sound wave, its conversion into nerve impulses, their transmission to the auditory centers, analysis and integration of sound information. The frequency, strength and timbre of sounds are differentiated. With the help of speech, people communicate. Thanks to auditory memory, you can find out whether a voice belongs to a specific person, animal or sound - an object. Auditory system
  8. Hearing Disorders
    Hearing impairment is indicated by the term “hypacusia”; hearing loss i.e. deafness, denoted by the term “cashew,” or “surditas.” Unilateral damage to the auditory zone of the cerebral cortex, the pathways from the nuclei of the auditory nerve and the optic tubercle does not lead to hearing impairment, since impulses from the nuclei of the auditory nerve come into the cerebral cortex of their own and opposite sides. In that
  9. Causes of Persistent Hearing Impairment
    Persistent hearing impairment in children can be congenital and acquired. It should be noted that such a unit is almost often difficult to implement. The conclusion about the congenital or acquired nature of hearing impairment is usually made on the basis of information obtained from the words of the parents, and this information is often very inaccurate. On the one hand, the disease that caused
  10. Classification of Persistent Hearing Impairment
    The main purpose of the classification of hearing impairment in childhood is to promote the proper organization of upbringing and training of children with hearing impairments, that is, firstly, the rational construction of a network of preschool and school institutions for such children; secondly, the proper selection of children in these institutions; thirdly, the proper organization of the pedagogical process. Important criterion
  11. Congenital and perinatal hearing impairment
    CODE ICD-H90 Conductive and sensorineural hearing loss. EPIDEMIOLOGY In recent years, more than 1 million children and adolescents have been diagnosed with hearing pathology in Russia. For 1000 physiological births, one deaf child is born. In 20-40 children out of 1000 infants who received intensive care, deafness and severe hearing impairment are determined. However, given the complexity of early diagnosis

    Of all the violations of the normal structure and functions of the hearing organ, mainly diseases, injuries, and abnormalities in the development of the auditory organ that can lead to persistent hearing impairment and therefore are of practical interest to the teacher and educator will be described here. In the topic of the physiology of the auditory analyzer, it was indicated that in the auditory organ distinguish sound-conducting

    Deaf children. In this case, they speak of severe hearing impairment. After creating the necessary contact, when the child feels confidence in the researcher, it is necessary to begin the study of hearing. In school conditions, the method of loud and whispering speech is used. In equipped rooms special audiometers are used. What features can be clarified by a brief examination of a deaf child?

  19. Persistent hearing impairment
    Persistent hearing impairment includes deafness and hearing loss. With deafness due to impaired neurosensory systems (the Corti's organ and / or nervous apparatus of the auditory analyzer), the perception of sounding speech only by ear is impossible under any circumstances, since not only is the threshold for auditory perception significantly increased, but the frequency range of perceived sounds is also limited ( up to 3.5-4 kHz and
