목적: To compare and validate on thresholds in brain evoked response audiometry (BERA) for single patient based on the performed hospitals and used devices 방법:The data was obtained in evaluating hearing disability of medical consultation for patients with noise induced hearing loss from 2016 to 2018. They underwent two or more BERA tests at the different hospitals and consisted of 42 males, so that the number of ears were 84. The average age was 62.5 (STD 5.0) years old. The test results were analyzed based on the test-performed 6 hospitals and used devices. Those 5 devices were navigator pro, Eclipse, Audera, Viking, and Smart EP. 결과:The maximum difference of the thresholds between two hospitals was 35dB. The number of the difference over 30dB, 20 to 30dB, 10 to 20dB and less than 10dB was 1, 11, 23 and 49. Three of 6 hospitals showed a skewed thresholds distribution. Four of 5 devices had an even thresholds distribution. However, one device tended to show the better thresholds than the other devices. 결론:Based on our analysis, it is concluded that the BERA thresholds were affected by some of used devices and performed hospitals. To standardize the BERA thresholds, the device and its usage should be investigated in the future.
