Abstract:
OBJECTIVE:The latency-intensity function (LIF) of wave V from click ABR of some deaf children showed great variation. We attempted to find out the intrinsic reasons.
METHOD:The children recieved tone-burst ABR test.
RESULT:Frequencies from 0.5-4.0 kHz have been tested and the thresholds of tone-burst ABR were recorded. The average thresholds of steeply LIF children at 0.5-4.0 kHz were (93.13 ± 7.04), (79.37 ± 7.72), (69.38 ± 8.54) (66.25 ± 8.06) dB respectively, while the average thresholds of shallower LIF children at these 4 frequencies were (65.00 ± 7.32) (68.13 ± 6.55) (70.63 ± 6.80) (78.12 ± 8.34) dB respectively.
CONCLUSION:The results imply that the child with steeply LIF may have more hearing loss at frequencies 0.5 and 1 kHz than those with shallower LIF. LIF may predict the audiogram configuration.
