Introduction. In the twenty-first century, it's hard to imagine life without gadgets. The advent of technology promised changes in all spheres of modern human life and the medical field is no exception: in our work we want to show one of the ways to use modern technologies in the form of the application of the Petralex software, jointly created with the BGUIR Educational Institution. Goal. The aim of our study is to increase the effectiveness of screening for hearing impairment in certain groups of people. Materials and methods. For the research, we used the Petralex software installed on a modern smartphone. The study was conducted with the participation of school-age children. Results. According to the results of the work carried out, this method has shown effectiveness in detecting hearing aid pathologies in the early stages in school-age children. The advantages of this method are: accessibility, since the application works on any modern mobile device, you can take an audiogram at home in a few minutes; cheapness, since it does not require large financial costs; easy setup of the application without the help of a specialist in automatic mode. Conclusions. Having assessed the effectiveness of this study, it is planned to carry out this method in adults in the future.

Introduction. Hearing is one of the most important functions of our body, thanks to which we receive a huge flow of information from the outside world every day. The absence of hearing impairment is a guarantee of attentiveness, easy learning, and good communication. The deterioration of hearing function deprives people of the opportunity to communicate with others, to fully perceive information from outside. According to WHO, by 2021, more than 5% of the world's population has hearing impairments, of which 0.4% are children. According to forecasts, by 2050, almost 2.5 billion people will suffer from hearing loss. The World Health Organization has estimated that the lack of assistance for hearing loss costs the world $980 billion annually. Based on the above, it can be argued that this problem is relevant for people of any age. There are many factors that lead to hearing disorders, for example: heredity, a foreign body in the ear, defects in the eardrum, infections, tumors, traumatic brain injuries, occupational factors, and so on. Many of these causes can be prevented if early diagnosis is carried out in the most at-risk groups. These include: newborns and infants; preschool and school-age children; people exposed to noise or chemicals at work; people taking ototoxic medications. One of the methods of detecting hearing organ pathology is the introduction of screening programs. Hearing testing in school-age children is an important part of identifying disorders that were not recognized at birth or whose hearing loss occurred at a later period. Ensuring consistent protocols, learning verification and follow-up at school age will help ensure the modern identification and rehabilitation of children with hearing loss [3]. Screening allows you to divide the population into people with a positive and negative test result (probably sick or probably healthy). If the test result is positive, then clinical and laboratory confirmation of the diagnosis should be carried out. The purpose of the work. The aim of our study is to increase the effectiveness of screening for hearing impairment in certain groups of people using the Petralex software installed on a modern smartphone. Materials and methods of research. For the research, the specialists of the UO "BGUIR" and the UO "GrSMU" jointly developed and used the Petralex software within the framework of the concluded cooperation agreement. Modern smartphones are equipped with an audio subsystem that can be used to generate audio signals with a discretionary frequency of 44.1 kHz, which is enough to implement tonal audiometry tests on it. The equipment is tested using conventional headphones relative to the average hearing threshold. To obtain an average hearing threshold, calibration is performed, during which the hearing thresholds for ten healthy young people with good hearing are determined for this phone and this type of headphones. The results obtained are averaged and taken as the "average audibility threshold". The study involved schoolchildren of grades 5-9 of the educational institution "Secondary School No. 23 of Grodno" in the number of 200 people, whose parents we took informed consent to conduct screening. Before conducting the study, the child was explained the progress of the work and began to carry it out. The student put on headphones, in which sound signals were alternately applied to the right and left ear at different frequencies with increasing amplitude: 125, 250, 500, 1000, 2000, 3000 ,4000 and 8000 Hz. And at the moment when the student heard the beep, he pressed the phone screen. All the results were saved on the smartphone, indicating the full name of the students, age, class. After passing the test, a tonal audiogram (Figure 1) appeared on the screen for the right and left ears according to the aerial type of sound transmission, which we further evaluated. The results of the study. During the period from October 14, 2023 to January 31, 2024, we performed 200 studies. As a result of the study, 25 children with suspected pathology of the auditory analyzer were identified. Of these, 8 children suffer from hearing impairment in both ears, 10 children suffer from hearing impairment in the right ear, and 7 children suffer from hearing impairment in the left ear. The total percentage of children with suspected hearing pathology is 12.5%. Table 1 Percentage of children with suspected pathology of the auditory analyzer, depending on the class <table> <tbody> <tr> <td width="129"> </td> <td width="129"> 5 class </td> <td width="129"> 6 class </td> <td width="129"> 7 class </td> <td width="129"> 8 class </td> <td width="129"> 9 class </td> </tr> <tr> <td width="129"> The number of students who took part in the study </td> <td width="129"> 40 </td> <td width="129"> 45 </td> <td width="129"> 36 </td> <td width="129"> 38 </td> <td width="129"> 41 </td> </tr> <tr> <td width="129"> Students with suspected pathology </td> <td width="129"> 6 </td> <td width="129"> 2 </td> <td width="129"> 5 </td> <td width="129"> 3 </td> <td width="129"> 9 </td> </tr> <tr> <td width="129"> Percentage of students with suspected pathology </td> <td width="129"> 15% </td> <td width="129"> 4,44% </td> <td width="129"> 13,9% </td> <td width="129"> 7,9% </td> <td width="129"> 22% </td> </tr> </tbody> </table> After completing the study, children with suspected hearing pathology were recommended to undergo an in-depth audiological examination, which was performed by 25 students. As a result, the most common cause of hearing impairment is pathology of the outer ear (sulfur plug) -9 schoolchildren. Pathology of the middle ear (exudative otitis media) -5 students. Sensorineural pathologies - 1 person (registered with a sign language therapist). Conclusion. Based on the results of the work, we can say that this method will greatly simplify and help identify the pathology of the auditory analyzer at an earlier date. Therefore, we plan to conduct such a study in adults as the next stage.
