- Abstract
Objectives: The goal was to evaluate the accuracy with which the QASSR method predicts behavioral thresholds in adult patients with sensorineural hearing loss. Material and methods: QASSRs were analyzed for thresholds and magnitude/phase characteristics. Tone-burst ABR was recovered from QASSR signal and analyzed in the time domain. The QASSR and recovered ABR thresholds were compared to behavioral thresholds. Results: All mean threshold estimates differed less than 3 dB for QASSR and less than 5 dB for ABR at 1 k, 2 k and 4 kHz. The largest differences were observed for both at 0.5 Hz (5.63 and 11.56 dB). Conclusions: QASSR method merges two dissimilar stimulation techniques, transient and steady-state, to create a hybrid stimulation-and-analysis paradigm that seems to improve the overall performance of the electrophysiological threshold estimation.
