SYSTEM OF ANALYSIS OF THE OBJECTIVE METHODS DATA IN DIAGNOSTICS OF HEARING
The solution of the early diagnosis of human diseases hearing problem is relevant for ongoing preventive population surveys. For purposes of the hearing diagnostics traditionally used are the subjective methods of examination, such as tone and speech audiometry and the objective methods, one of which is tympanometry. These methods provide a graphical representation of the results. On the qualitative and quantitative assessment of the results, particularly in the analysis and decision-making on characteristics such as the shape and configuration of the tone audiogram, speech audiogram and tympanograms affects subjectivity of evaluation by different experts. This difference in estimates can be significant, affecting the accuracy of the diagnosis. In this paper, a block diagram of biotechnical system diagnostics of hearing impairment, which allows realizing the statistical methods of tympanograms analysis. Using the raw data results of impedance audiometry tympanogram for a patient with a diagnosis of otitis a regression analysis of the type C tympanograms has been conducted. Calculated is the average value of the correlation coefficient for pressure inside the eardrum and standard deviation. Построенные корреляционные плеяды позволили сократить число связей анализируемых параметров за счет исключения менее статистически значимых. On the basis of the results of the tympanograms correlation link evaluation the correlation graphs are built. In the tympanograms analysis the Spearman's rank correlation coefficient has been used. In accordance with the standard correlation coefficient values established have been the links for which the value of the correlation coefficient was below the threshold. The built correlation galaxies have allowed reducing the number of links between the analyzed parameters by eliminating the less statistically significant.
