Cortical Auditory Evoked Potential: Evaluation of Speech Detection in Hearing Aid Users

Cortical Auditory Evoked Potential: evaluation of speech detection in adult hearing aid users.

PURPOSE To analyze the presence of auditory cortical potential and its correlation with psychoacoustic detection of speech sounds as well as the latency of the P1, N1 e P2 components presented in free field in hearing impaired adults with and without amplification. METHODS We evaluated 22 adults with moderate to severe symmetrical bilateral sensorineural hearing loss, regular users of bilater...

Speech-evoked cortical auditory responses in children with normal hearing.

OBJECTIVE Cortical auditory-evoked potentials (CAEPs), an objective measure of human speech encoding in individuals with normal or impaired auditory systems, can be used to assess the outcomes of hearing aids and cochlear implants in infants, or in young children who cannot co-operate for behavioural speech discrimination testing. The current study aimed to determine whether naturally produced ...

Monitoring auditory cortical plasticity in hearing aid users with long latency auditory evoked potentials: a longitudinal study

OBJECTIVE The objective of this study was to compare long-latency auditory evoked potentials before and after hearing aid fittings in children with sensorineural hearing loss compared with age-matched children with normal hearing. METHODS Thirty-two subjects of both genders aged 7 to 12 years participated in this study and were divided into two groups as follows: 14 children with normal heari...

Sensitivity of cortical auditory evoked potential detection for hearing-impaired infants in response to short speech sounds

Cortical auditory evoked potentials (CAEPs) are an emerging tool for hearing aid fitting evaluation in young children who cannot provide reliable behavioral feedback. It is therefore useful to determine the relationship between the sensation level of speech sounds and the detection sensitivity of CAEPs, which is the ratio between the number of detections and the sum of detections and non-detect...
