Objective To study the application of CE-Chirp in the evaluation of hearing impairment in forensic medicine by testing the auditory brainstem response （ABR） in adults using CE-Chirp to analyze the relationship between the V-wave response threshold of CE-Chirp ABR test and the pure tone hearing threshold. Methods Subjects （aged 20-77 with a total of 100 ears） who underwent CE-Chirp ABR test in Changzhou De’an Hospital from January 2018 to June 2019 were selected to obtain the V-wave response threshold， and pure tone air conduction hearing threshold tests were conducted at 0.5， 1.0， 2.0 and 4.0 kHz， respectively， to obtain pure tone listening threshold. The differences and statistical differences between the average pure tone hearing threshold and V-wave response threshold were compared in different hearing levels and different age groups. The correlation， differences and statistical differences between the two tests at each frequency were analyzed for all subjects. The linear regression equation for estimating pure tone hearing threshold for all subjects CE-Chirp ABR V-wave response threshold was established， and the feasibility of the equation was tested. Results There was no statistical significance in the CE-Chirp ABR response threshold and pure tone hearing threshold difference between different hearing level groups and different age groups （P>0.05）. There was a good correlation between adult CE-Chirp ABR V-wave response threshold and pure tone hearing threshold with statistical significance （PPConclusion The use of CE-Chirp ABR V-wave response threshold can be used to evaluate subjects’ pure tone hearing threshold under certain conditions， and can be used as an audiological test method for forensic hearing impairment assessment. |
