Cortical auditory evoked potentials were recorded in cochlear implant recipients and in individuals with normal hearing using a speech stimulus. Responses were acquired over two test sessions to investigate between group differences and test repeatability. Results indicate significant differences in N1-P2 latency and amplitude measures between cochlear implant recipients and individuals with normal hearing.

This paper discusses a study that collected cortical evoked responses when stimuli of different modalities were presented.

Speech-evoked auditory brainstem responses (ABRs) were acquired in quiet and in the presence of noise at two study sessions to investigate 1) test-retest variability and 2) subcortical representation of speech stimuli. Participants were adults with normal hearing in both ears who listened monaurally and adults with unilateral deafness. Results indicate consistency in responses across sessions and several differences between hearing groups for magnitudes of discrete components.

The primary objective of this research study is to determine if various body positions for ocular vestibular evoked myogenic potential (oVEMP) testing demonstrate differentiation of the saccule and utricle through threshold responses.

This paper is a review of the electrophysiology of the cochlea and the auditory nerve--the behavior of the acting potential, the cochlear microphonics and the summating potential under identical conditions.
Resumo:
This paper compares the auditory steady state response (ASSR) thresholds with the click-evoked and tone burst auditory brainstem response (ABR) thresholds in their ability to predict known behavioral thresholds in normal-hearing adults.

Little is known about the way speech in noise is processed along the auditory pathway. The purpose of this study was to evaluate the relation between listening in noise using the R-Space system and the neurophysiologic response of the speech-evoked auditory brainstem when recorded in quiet and noise in adult participants with mild to moderate hearing loss and normal hearing.

This paper reviews a study to determine if loss of speech discrimination is related to age and patients with audiograms showing steep high-frequency losses.
Resumo:
This paper discusses a study conducted to test sound discrimination abilities of the chinchilla.

This paper is a review of auditory training using amplification for hearing impaired children.
Resumo:
This paper is a review of a study to compare latencies of early evoked responses in young children with those of adults.

This paper discusses auditory perception differences in aphasic and non-aphasic children

The purpose of this project was to determine whether a monaural FM or binaural FM fitting strategy is more appropriate for children with Auditory Processing Disorders.
Resumo:
This paper studies the auditory, visual and combined audio-visual recognition of vowels by severely and profoundly hearing impaired children.

This paper details a technique for training auditory memory for length of speech sounds in preschool children with a profound hearing loss.
