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. Each doctor produces a constant intensity of whispering speech, corresponding to the intensity of speech of other doctors. To do this, you need to pronounce numbers or words after a quiet exhalation. With hearing loss, to avoid reading from the speaker’s lips, the patient should not look at the doctor, so he turns sideways to him. The patient closes the opposite ear tightly with his index finger.

In practice, double-digit numbers from 21 to 99 according to Bezold (Bezold F., 1896), ii? Ia aini? Eyoey eioi? Uo 5-6 i are most often used. The doctor becomes at a distance of 6 m from the patient and utters a whisper of numbers. The examinee must repeat correctly three digits in a row. If the patient does not hear them, then the doctor approaches him one step and continues the study.

Hearing acuity is determined with an accuracy of 0.5 m and is reflected in medical documents: hearing on SR 0.5 / 6 i (a? Eneeoaea oeacuaaaony? Annoiyiea aini? Eyoey oaiioiie? A? Ei? Aaui ooii, a ciaiaiaoaea - eaaui).
When perceiving whispering speech in the auricle, a recording is made: hearing on the SR ad concham / 6 m. When perceiving whispering speech at a distance of less than 1 m, hearing is studied in colloquial speech. If the spoken language is less than 1 m, then to exclude one-sided deafness and listening, it is better to hear with the ear, the latter is drowned out with a Barani rattle and the scream is perceived worse by the hearing ear. The result of hearing research in colloquial speech is marked similarly to whispering - hearing at PP 5 /? 6 m, and the perception of screaming - CU. ? / 0. In medical institutions, these data are entered by otolaryngologists in the auditory passport of the medical history, and in military units they are recorded in the medical book after the description of the otoscopic picture.

Before the introduction of tonal and speech audiometry into practice, special tables of words of the bass and treble groups were used for the differential diagnosis of impaired sound conduction and sound perception. An example of the bass group of the table of words of V.I.Voyachek (1906) are the words: thief, won, window, and the treble - Sasha, a cup, burn, hare, etc.

The intensity of whispering speech is 20-30 dB, conversational speech - 40-60 dB, screaming - 80-90 dB. Scream immunity is considered social deafness.

Speech Research

  1. Hearing impairment while hearing loss
    The development of speech of hearing-impaired (hearing-impaired) children is affected by the time of onset of hearing loss, the degree of hearing loss, the general condition of the child, and the nature of the medical and pedagogical impact in each particular case. Even slight hearing loss, which occurred before speech was formed (at 2.5 - 3 years), leads to its underdevelopment. If she came after three years, the child’s speech is relatively

    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
  4. 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
  5. 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
  6. 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, hearing change in noisy
  7. 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
  8. 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
    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
  10. The study of the organs of speech
    The study of the speech organs in a child with speech impairments begins with collecting an anamnesis (from the Greek anamnesis - memory) - information about the previous general and speech development of the child. This information is usually obtained by interviewing the parents or other close relatives of the child. The circumstances accompanying the occurrence of speech impairment and prior
  11. Study of the content of the image of the Armed Forces with the help of a psychosemantic experiment
    The results of the theoretical analysis and substantiation of the provisions on the essence and structure of the image of the Armed Forces within the framework of well-known methodological approaches made it possible to develop a methodological concept for the corresponding experimental work. Based on the hypothesis that the image of the Armed Forces of Russia depends on the identity of young people and the constructed theoretical image model, the main
  12. 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
  13. Diagnosis of hearing impairment
    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?

Congenital hearing impairment can be hereditary. Hereditary hearing loss of an isolated form; characteristics.
