Pareniuk D. Investigation of the connection between induced otoacoustic emission and hearing properties determined by audiology for the hearing properties estimation of biological objects

The dissertation is based on the analysis of the results obtained during the study of the state of hearing channel of a biological object by implementation of the otoacoustic emission - by using the normalizing criterion and conducting statistical and comparative analysis of the consequences of its application; application of the coefficient of assessment of the quality of the hearing test by objective and subjective methods; evaluating the results of exposure of a biological object to the superposition of different in nature psychoactive factors - music therapy and stress factor and the search for new criteria to determine the type of this influence. The object of research is the passage of the acoustic wave through the middle ear to the inner ear and response to it’s influence in the opposite direction, the response of the brain to the action of superposition of psychoactive factors and their individual effects. The subject of the study was the auditory system of humans and guinea pigs, which was and was not exposed to drugs, the brain, which was and was not psychoactively affected by the superposition of influencing factors or their individual influences.
