The purpose of this project is to examine the relationship between the fine structures of DPOAE and those of the hearing threshold. An experiment was conducted with 12 subjects. Their hearing threshold was screened using an implemented audiometer with high frequency resolution and based on level presentation strategy. Measurements of the distortion product otoacoustic emissions (DPOAE) were also performed with a high frequency resolution. A developed fine structure detector was applied to extract objective parameters characterizing the threshold and DPOAE fine structure. A direct relation between the threshold and DPOAE fine structure and level could not be found. However, similarities in the fine structure periodicity were observed. The analysis of the results and their comparison with simplified cochlear models did not provide a universal tool for an estimation of the threshold from the DPOAE fine structure and level.
