摘要：

Auditory brainstem response (ABR) thresholds to air and bone conducted clicks were investigated in 20 full-term neonates and 20 normal-hearing young adults. Results showed mean ABR thresholds to air and bone conducted clicks for neonates to be 3.75 dB nHL (40.75 peak SPL) and 1.25 dB nHL (36.25 dB peak re: 1 muN), respectively, and for adults 3.75 dB nHL (40.75 peak SPL) and 18.75 dB nHL (53.75 peak re: 1 muN), respectively. A significant difference was observed in mean ABR thresholds to bone conducted stimuli between neonates and adults (p < 0.0001) and among mean adult ABR thresholds to air and bone conducted stimuli (p < 0.0001). Nonsignificant differences were observed in mean ABR thresholds to air and bone conducted stimuli among neonates (p > 0.05) and in mean ABR thresholds to air conducted stimuli between neonates and adults (p = 1.00). It is speculated that the dissimilarity in the relationship of thresholds to air and bone conducted stimuli between neonates and adults reflects, in part, a difference in efficiency of signal delivery to the cochlea.
