Abstract:

Objective  To explore the prediction of bone-conduction of audiometric(BC-A) threshold in normal-hearing  adults using multiple auditory steady-state response(ASSR). Methods  BC-ASSR and BC-A were recorded in 20 normal-hearing adults(10 males and 10 females). The response thresholds and the behavioral thresholds were compared at 0.5, 1.0, 2.0 and 4.0kHz to get the correlation and regression formulae. Results  There were no significant differences between the men and women for the response thresholds. There was a significant difference at 4kHz for BC-ASSR. At the other three frequencies, no significant differences were found. Pearson correlation coefficients between the response thresholds and the behavioral thresholds were 0.95, 0.91, 0.26 and 0.29 at 0.5, 1.0, 2.0 and 4.0kHz. Conclusion  BC-ASSR can only be used to predict the BC-A  at 0.5 and 1.0kHz. The correlation between the response thresholds of BC-ASSR and BC-A is not strong.
