Abstract
Objective: To evaluate the audiometric usefulness of the auditory steady-state response (ASSR) using the multiple auditory steady-state response (MASTER®).<br>Design: (1) In normal adults (aged 25-45 years old), comparisons of the behavioral thresholds for pure tones and the ASSR thresholds were compared. (2) In supposedly normal infants (aged 3-45 months old), the click ABR thresholds and ASSR thresholds were compared. (3) In patients (aged 6-81 years old), the behavioral thresholds for pure tones, the ASSR thresholds, and click ABR thresholds were compared.<br>Results: (1) In normal adults, the behavioral thresholds for pure tones of 0.5, 1, 2, and 4kHz were 9.7±4, 7.8±3.5, 8.9±5, and 6.1±6.3dB, respectively. In addition, the ASSR thresholds for carrier frequencies of 0.5, 1, 2, and 4kHz were 40.6±9.4, 33.9±7, 29.4±5.4, and 32.8±4.6dB, respectively. (2) In the infants, the click ABR thresholds were 20±7.3dB, while the ASSR thresholds for carrier frequencies of 0.5, 1, 2, and 4kHz were 55±9.3, 44.4±13.9, 34.8±11.6, and 40.7±14.4dB, respectively. (3) In the patients, correlation coefficients of behavioral thresholds and ASSR thresholds were 0.65 at 0.5kHz, 0.85 at 1kHz, 0.82 at 2kHz, and 0.77 at 4kHz. The correlation coefficients of behavioral thresholds and click ABR thresholds were 0.80 at 0.5kHz, 0.86 at 1kHz, 0.90 at 2kHz, and 0.83 at 4kHz.<br>Conclusion: On average, the thresholds for the ASSR were higher than the behavioral thresholds, and the discrepancies were larger at low frequencies. For a better physiologic audiometry estimation of the lower frequencies, the optimal modulation frequency should be investigated.
