ABSTRACT
Objective To investigate the relationships of tone burst -ABR Thresholds and the pure -tone audiograms in normal hearing adults .Methods The response thresholds of Tone burst -ABR and the pure -tone audiogram were recorded from 34 adult(68 ears) at 0 .5 ,1 .0 ,2 .0 ,and 4 .0 kHz .The results were statistically ana-lyzed .The correlation of the response thresholds of tone burst -ABR and the pure-tone audiogram were studied . Results At 0 .5 ,1 .0 ,2 .0 ,4 .0 kHz ,the averages of the response thresholds of tone burst -ABR were 27 .43 ± 3 .29 ,25 .98 ± 2 .76 ,16 .78 ± 2 .37 ,and 12 .42 ± 2 .64 dB nHL ,respectively .The averages of the pure -tone audio-gram were 12 .23 ± 3 .99 ,11 .82 ± 2 .56 ,9 .58 ± 3 .23 ,and 9 .92 ± 2 .59 dB nHL ,respectively .The differences between the response thresholds of tone burst -ABR and the pure-tone audiogram were 12 .13 ± 4 .51 ,11 .43 ± 3 .66 ,7 .61 ± 2 .43 ,and 7 .17 ± 1 .32 dB ,respectively .At 0 .5 ,1 .0 ,2 .0 ,and 4 .0 kHz ,Pearson correlation coefficients were 0 .69 ,0 .79 ,0 .84 ,0 .89 ,respectively .Conclusion The tone burst -ABR and the pure -tone audiogram thresholds were a highly correlated with each other ,especially at 2 .0 kHz and 4 .0 kHz .Tone burst -ABR has the frequency specificity ,which can response the hearing level better .
