Cortical Auditory Evoked Potentials in Persons Using Hearing Aids.
A review of literature on usefulness of Cortical Auditory Evoked Potentials in verifying the usefulness of hearing aid shows equivocal results and a majority of the studies are carried out in a research laboratory.
The aim of the present investigation was to investigate the usefulness of recording CAEPs for verification of hearing aids in a clinical set up.
The results revealed that in aided condition, the detectability of CAEP responses was more when compared to unaided condition in persons with hearing impairment. There was a significant difference between the unaided CAEP responses of persons with hearing impairment and CAEP responses of persons with normal hearing. However, no such difference was
observed between aided CAEPS responses of persons with hearing impairment and those of normal hearing.
CAEPs can be reliably recorded in a clinical set up from individuals using hearing aids. The detectability of responses increases when a person is wearing hearing aid. CAEPs will be helpful in verification of hearing aids especially in persons with moderately severe to severe hearing loss.
The advancement in the field of pediatric audiology has resulted in early, efficient and objective measures of hearing threshold estimation for infants. This has provided with the ability to fit
appropriate hearing aid at a very young age.
Verification of the selected hearing aid in infants
and small children is a challenging task as it is difficult to obtain reliable behavioral measures
from them. There is a need to use electrophysiological measures for such population.
