Hearing aid amplification can be used as a model for studying the effects of auditory stimulation on the central auditory system (CAS). We examined the effects of stimulus presentation level on the physiological detection of sound in unaided and aided conditions. P1, N1, P2, and N2 cortical evoked potentials were recorded in sound field from 13 normal-hearing young adults in response to a 1000-Hz tone presented at seven stimulus intensity levels. As expected, peak amplitudes increased and peak…

Aided cortical auditory evoked potentials in response to changes in hearing aid gain
The results reinforce the notion that hearing aids modify stimulus characteristics such as SNR, which in turn affects the CAEP in a way that does not reliably reflect hearing aid gain.
Cortical Auditory Evoked Potentials in (Un)aided Normal-Hearing and Hearing-Impaired Adults.
Audibility of the signal, which in some cases is determined by the signal level relative to threshold and in other cases by the SNR, is the dominant factor explaining changes in CAEP amplitude, which can potentially be used to assess the effects of hearing aid gain in hearing-impaired users.
The Effect of Intensity on the Speech Evoked Auditory Late Latency Response in Normal Hearing Individuals.
There is a significant effect of intensity on the latency and amplitude of ALLR in speech stimulus, however, this effect may vary for different speech stimuli.
Evaluation of Auditory Evoked Potentials as a Hearing aid Outcome Measure
This thesis aimed to explore the applicability of Cortical Auditory Evoked Potentials (CAEPs) and Envelope Following Responses (EFRs) as objective aided outcome measures for use in infants wearing
Cortical Auditory Evoked Potential: evaluation of speech detection in adult hearing aid users.
There was increase in the presence of cortical auditory evoked potential with hearing aids and automatic detection of cortical response showed 91% agreement with the psychoacoustic perception of the speech signal.
Aided Electrophysiology Using Direct Audio Input: Effects of Amplification and Absolute Signal Level.
Results of this study demonstrate that factors in addition to SNR must also be considered before CAEPs can be used to clinically to measure aided thresholds, and demonstrate that larger area measures were found at higher levels.
Cortical auditory-evoked potentials (CAEPs) in adults in response to filtered speech stimuli.
CAEP evaluation was found to be more accurate than audibility predictions, based on threshold and hearing aid response measures, and are a sensitive tool for directly evaluating the audibility of speech sounds, at least for adult listeners.
Cortical encoding of speech acoustics: Effects of noise and amplification
Abstract Objective: To investigate speech stimuli and background-noise-dependent changes in cortical auditory-evoked potentials (CAEPs) in unaided and aided conditions, and determine amplification
Clinical Use of Aided Cortical Auditory Evoked Potentials as a Measure of Physiological Detection or Physiological Discrimination
Results demonstrate that clinical use of aided CAEPs may be justified when determining whether audible stimuli are physiologically detectable relative to inaudible signals, but differentiating aidedCAEPs elicited from two suprathreshold stimuli is problematic and should not be used for clinical decision making until a better understanding of the interaction between hearing-aid-processed stimuli and CAEP's can be established.
Slow Cortical Potentials and Amplification—Part II: Acoustic Measures
Acoustic results indicate that aided SCP results must be cautiously interpreted and that further research is required for clinical application, and gain achieved by the hearing aids was less than real-ear insertion gain measured with standard hearing aid test signals.


Effects of Sensorineural Hearing Loss and Personal Hearing Aids on Cortical Event-Related Potential and Behavioral Measures of Speech-Sound Processing
The results suggest that hearing-impaired individuals’ brains process speech stimuli with greater accuracy and in a more effective manner when these individuals use their personal hearing aids.
Auditory stimulus processing at different stimulus intensities as reflected by auditory evoked potentials
Amplitude and latency studies of the averaged auditory evoked responses to tones of different intensities.
It was found that “saturation” and decline arise at relatively low sensation levels in persons with unilateral deafness as compared with persons having normal hearing, suggesting that the AER generating mechanism contains two relatively independent symmetrical systems which are unequally influenced by the ipsilateral and contralateral cochleae.
Neural Representation of Amplified Speech Sounds
Speech-evoked cortical potentials can be recorded reliably in individuals in both aided and unaided conditions during hearing aid use, and a better understanding of how amplification (and device settings) affects neural response patterns is still needed.
The effect of broadband noise on the human brainstem auditory evoked response. I. Rate and intensity effects.
It was found that noise levels above about 40 dB SPL increase the latency and decrease the amplitude of wave V, regardless of click intensity, whereas the effects of a constant noise level on wave V latency decrease at higher click intensities.
New Perspectives on Assessing Amplification Effects
This review presents a multistage framework for understanding how a hearing aid affects performance, and describes methodology and research on 2 new assessment techniques: acoustic analysis of speech measured at the output of the hearing aid and auditory evoked potentials recorded while the listener wears hearing aids.
Long latency auditory evoked potentials: intensity, inter-stimulus interval, and habituation.
It was concluded that intensity and inter-stimulus interval interact to determine AEP amplitude as well as latency values and that the constituent components do not change appreciably with repeated stimulus presentations, even after several days.
The Neural Representation of Consonant-Vowel Transitions in Adults Who Wear Hearing Aids
The authors report that the neural detection of time-varying acoustic cues contained in speech can be recorded in adult hearing aid users using the acoustic change complex (ACC).
Frontal auditory evoked potentials and augmenting-reducing.
Electrophysiological investigation of auditory recruitment by averaged electroencephalographic-evoked response.
The studies revealed a very significant increase of the slope of the least-squares regression line in recruiting subjects compared with normal subjects and the relation between the amplitude of the auditory-evoked response and the intensity of the stimulation could be expressed nearly equally well by a logarithmic function and a power function.
