Relevance: Any kind of the hearing loss, especially in the childhood, affects the mental and intellectual development negatively as well as behavior and social position of a deaf patient in the hearing world. Cochlear implantation is the most effective and reliable method of medical and educational auditory-speech rehabilitation for both adults and children with severe hearing loss and deafness. One of the key performance indicators of the cochlear implantation is a result of speech audiometry, especially on the noise background. The aim is to study the state of auditory function according to the subjective audiometry in the noise background and the influence of various factors on the effectiveness of rehabilitation of the children after cochlear implantation. Materials and methods: The study involved 150 children with severe sensorineural hearing loss and deafness after cochlear implantation. In age, they ranged from 3 to 18 years old. Evaluation of the efficiency of cochlear implantation was carried out in several stages. All studies were done in the free-field with the cochlear implant on. At first, we performed the pure tone audiometry. Then we defined the 50% intelligibility threshold of numeral test. After that, we defined a word recognition percentage. And finally we defined the impact of masker on speech intelligibility at SPL of useful signal 50, 60 and 80 dB. Results: Based on the analysis of the received data, all children with severe sensorineural hearing loss and deafness after cochlear implantation were divided into 3 groups depending on the speech intelligibility. The first group (high efficiency of cochlear implantation) included 68 children (45,3%). This group was divided into two subgroups depending on the difference between the values of the speech intelligibility in the free sound field and in the noise background. The second group (average efficiency) consisted of 45 children (30%). The third group (low efficiency) were 37 children (24,7%). The influence of various factors on the efficiency of cochlear implantation was analyzed. Conclusion: Speech intelligibility in the noise background must be examinated in all children after cochlear implantation. The main factors affecting the effectiveness of cochlear implantation according to test of speech intelligibility in the noise background are the ethiology of hearing loss and duration of post-operation period. Results of speech intelligibility in the noise background test will help specialists who practice the rehabilitation of children after cochlear implantation (teachers for deaf, speech therapists) to pay attention to the decrease of speech intelligibility in children in the real conditions of communication and to focus their efforts on its improving with the appropriate methods.

Topicality: Dizziness is one of the most common symptoms in medical practice. This symptom can be caused by many diseases. One factor which is contributing to dizziness is mental disorders (including depression and anxiety). The problem of psychoemotional stress in recent decades is becoming increasingly important in the world. The COVID-19 pandemic, which was declared by the WHO in 2020, substantially deepened that problem. Numerous studies show that persons of working age suffer most from psychoemotional stress. An urgent task is a selection of scales and questionnaires for persons with dizziness caused by chronic stress. Aim: to increase the effectiveness of diagnosis and treatment of cochleovestibular disorders that caused under stress conditions and develop the rehabilitation events. Materials and methods: 95 patients aged 18 to 59 years were examined with complaints of dizziness caused by stress conditions and 20 people in the control group. 52 patients from main group also complained of tinnitus and 35 of hearing loss. The following studies were carried out for patients: audiometry in full, listening adaptation, detection tests for central auditory disorders, impedance measurement, short-patent auditory induced potentials (CSVP), vestibulometry. The questionnaire was conducted on the following scales: the questionnaire "Comprehensive Stress Assessment" (by Shcherbatykh YuV), the Hospital scale of Anxiety and depression (HADS), the Quality of Life Assessment Scale (by Chaban AS) and the Holmes and Reich social adaptation scale. Non-parametric methods were used for statistical analysis. The difference in comparing of the two independent aggregates was considered valid at p < 0.05. Results: All patients with psychogenic dizziness were divided into three groups depending on the severity of stress. The first group included 21 people (22.1%) with moderate stress, the second group – 35 patients (36.8%) with fairly pronounced stress, and at the third group were 39 people (41.1%) in a state of severe stress (but 10 of them are on the verge of exhaustion of the body's adaptive forces). The average indicators obtained during the questionnaire for the inquirer "Comprehensive stress assessment" in the 1st group were 9.0 (10.5-7) points, in the 2nd group – 17.5 (21-14.5) points and in the 3rd group – 34.0 (28-41.5). The results of the Hospital Anxiety Scale and Depression (HADS) questionnaire are: in 1st group more than half of the subanxiety scale studies was normal; none of the subjects showed clinically pronounced depression and only 3 of them (14.3%) showed subclinically pronounced depression. In group 2nd the anxiety component is more pronounced with a predominance of clinically expressed anxiety; depression was diagnosed only in 37.1% with a predominance of subclinically pronounced depression. In the 3rd group on the anxiety sub-scale, the normal results had only 2 persons (5.1%), moreover, clinical anxiety was prevalent in most patients. In according with subscale of depression, about a third of patients have normal indicators and almost half of the subjects tested have subclinically pronounced depression. According to the Holmes and Reich Social Adaptation Scale, in most cases (57 patients) there was low level of stress, 31 people had an average level of stress and only 7 had a high. The results of the assessment of life quality according to the Chaban A. S. scale: in eight categories, life quality indicators decreased inversely in proportion to the increase in the severity of stress. The best indicators were obtained in the category of satisfaction with living conditions. The worst indicators are in the categories of satisfaction with physical condition and love. Conclusions: 36.8% of the studied ones have quite pronounced stress of emotional and physiological systems, 41.1% - state of severe stress and 10.5% - exhaustion of the body's adaptive forces. Patients with dizziness that was caused by stress should be interviewed using validated scales: the questionnaire "Comprehensive Stress Assessment", the Hospital Anxiety Scale and Depression (HADS) and the Quality of Life Assessment Scale. The use of other scales to determine the psychoemotional state and quality of life of such patients is the subject for further researches. In according with used questionnaires from 7.4 (Holmes and Reich Scale of Social Adaptation) up to 78.9% (Hospital Anxiety and Depression Scale (HADS)) of working-age persons who were under stress, except for otolaryngological treatment, in need of a medical psychologist. These measures will provide an opportunity to increase the speed of the treatment process and improve patient’s quality of life.

The article substantiales the rationale for the Ukrainian translation of Kharshak numerals test. The authors noted the conditions they adhered to maintain phonetic balance. The description of the adaptation process of Kharshak numerals test and the final version of the translation into Ukrainian are given. The authors describe area for future research for the most effective test implementation in practice.

Topicality: The speech audiometry is an essential diagnostic method which allows to fully assess the effectiveness of the cochlear implantation and hearing aids, to identify the central auditory processing disorders among the patients. Ukrainian audiologists have all necessary tools to perform classical speech audiometry and determine speech discrimination in the difficult acoustic conditions in adults. But it should be said that Ukrainian speech tests for children haven’t been developed yet. Aim: to develop and implement the Ukrainian speech discrimination tests for children. To solve the problem of speech audiometry in Ukraine it was decided to develop several speech discrimination tests for children of different ages and needs. At the first stage the authors have formed the groups with Ukrainian words for speech audiometry in children (starting from preschool age) and made a studio recording of the test that should be tested and validated futher. The formed word groups meet with all the requirements for phonetically balanced speech discrimination tests taking into consideration the peculiarities of children’s audiometry. The following principles were adhered in each group: the presence of all Ukrainian vowel phonemes in the stressed syllable and consonants with different frequency; the presence of words with different numbers of syllables; taking into consideration the rhythmic structure of the word (stress place); keeping a constant ratio of vowels and consonants. The article presents the primary (not yet valid) version of the Ukrainian speech discrimination test for children’s audiometry. Studio recording of this test will be tested in children with normal and impaired hearing as well as in users of hearing aids and cochlear implants. Conclusions: For the first time in Ukraine the tables with words have been formed in the native language for the audiometry in children (starting from the preschool age). The studio recording of the speech discrimination test was done with the female voice. Hence the next phase of development of the Ukrainian speech tests for children is planned the sence of which will be to approbate and validate.
