Estimating Hearing Thresholds in Hearing-Impaired Adults through Objective Detection of Cortical Auditory Evoked Potentials.
BACKGROUND Hearing threshold estimation based on cortical auditory evoked potentials (CAEPs) has been applied for some decades. However, available research is scarce evaluating the accuracy of this technique with an automated paradigm for the objective detection of CAEPs. PURPOSE To determine the difference between behavioral and CAEP thresholds detected using an objective paradigm based on t...

Background: Cortical Evoked Response Audiometry (CERA) refers to prediction of behavioral pure-tone thresholds (500-4000 Hz) obtained by recording the N1-P2 complex of auditory long latency responses. CERA is the preferred method for frequency–specific estimation of audiogram in conscious adults and older children. CERA has an increased accuracy of determination of the hearing thresholds of ale...

Background & Aim: Auditory steady state response(ASSR) is an auditory evoked response that has received a lot of attention nowadays. At present, ASSR is mostly used to estimate pure-tone thresholds. Clinical evidence of ASSR in combination with findings for auditory middle latency response (AMLR) and 40 Hz response support the assumption that based on stimulus modulation rate, the ASSR anat...
متن کاملAutomated cortical auditory evoked potentials threshold estimation in neonates.
INTRODUCTION The evaluation of Cortical Auditory Evoked Potential has been the focus of scientific studies in infants. Some authors have reported that automated response detection is effective in exploring these potentials in infants, but few have reported their efficacy in the search for thresholds. OBJECTIVE To analyze the latency, amplitude and thresholds of Cortical Auditory Evoked Potent...
متن کاملDepth matters - Towards finding an objective neurophysiological measure of behavioral amplitude modulation detection based on neural threshold determination
With increasing numbers undergoing intervention for hearing impairment at a young age, the clinical need for objective assessment tools of auditory discrimination abilities is growing. Amplitude modulation (AM) sensitivity has been known to be an important factor for speech recognition particularly among cochlear implant (CI) users. It therefore would be useful to develop objective measures of ...
