Aim: The aim of the study was to compare the hearing threshold levels obtained by cortical auditory evoked responses and classic behavioral audiometry in adults with normal hearing and sensorineural hearing loss and to study the compatibility of these two tests. Methods: In this study 74 adults consisting of 18 normal hearing and 56 hearing impaired people were evaluated and hearing threshold levels obtained with both tests at 500, 1000, 2000 and 4000 Hz frequencies were compared. Results: The correlation between ALR and behavioral thresholds was found to be moderate at 1000 and 2000 Hz, poor at 4000 Hz and there was no correlation at 500 Hz in adults with normal hearing.On the other side in adults with hearing loss good correlation was found to be high at all of the tested frequencies. The biggest mean differences between two tests values were 5 dB in normal hearing people and 7.4 dB in hearing disorders people. Consequences: ALRs have shown good correlations with pure tone behavioral thresholds and it may be suggested as a reliable and accurate test to estimate pure tone thresholds in uncooperative adults and children, forensic cases and subjects with nonorganic hearing loss.
