The paper describes the unexpected finding of evoked otoacoustic emissions from one ear of a subject with severe-to-profound bilateral sensorineural hearing loss. It is suggested that the subject may have a group of surviving outer hair cells in some regions of the left cochlea with corresponding inner hair cell or neural damage. (Author/DB)

Simultaneous recordings of auditory brainstem and middle latency responses were obtained in both vertex-ipsilateral and vertex-contralateral derivations in 22 children, ages 8-12. For specific recording conditions, the latencies of middle latency responses differ significantly between children with and without learning disabilities, offering…

Results of applying the electrophysiological measure of auditory long latency event-related potentials (P3 AERP) on 20 children with central auditory processing disorders before and after a structured treatment program found a significant decrease in P3 latency and a significant increase in P3 amplitude when compared with control subjects who had…

Long-term effects on auditory electrophysiology from early fluctuating hearing loss were studied in 27 children, aged 5 to 7 years, who had been evaluated originally in infancy. Findings suggested that early fluctuating hearing loss disrupts later auditory brain stem electrophysiology. (Author/DB)

This study evaluated whether listeners can distinguish human brainstem auditory evoked responses elicited by acoustic clicks from control waveforms obtained with no acoustic stimulus when the waveforms are presented auditorily. Detection performance for stimuli presented visually was slightly, but consistently, superior to that which occurred for…

Simultaneous 3- channel recorded auditory brainstem responses (ABR) were obtained from 20 neonates with various high-pass filter settings and low intensity levels. Results support the advocacy of less restrictive high-pass filtering for neonatal and infant ABR screening to air-conducted and bone-conducted clicks. (Author/JDD)
