“…As the intensity of the stimulus increases, peak latencies decrease and peak amplitudes increase [Adler and Adler, 1989;Beagley and Knight, 1967;Botte et al, 1975;Bruneau et al, 1985;Butler et al, 1969;Khechinashvili et al, 1973;Martin and Boothroyd, 2000;McCandless and Best, 1966;Moore and Rose, 1969;Picton et al, 1977;Polich et al, 1988;Rapin et al, 1966;Roth et al, 1984;Spoor et al, 1969;Uziel and Seneclause, 1978]. The unaided results of this experiment are consistent with these published findings.…”

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 latencies decreased with increasing intensity for unaided and aided conditions. However, there was no significant effect of amplification on latencies or amplitudes. Taken together, these results demonstrate that 20 dB of hearing aid gain affects neural responses differently than 20 dB of stimulus intensity change. Hearing aid signal processing is discussed as a possible contributor to these results. This study demonstrates (1) the importance of controlling for stimulus intensity when evoking responses in aided conditions, and (2) the need to better understand the interaction between the hearing aid and the CAS.

“…The general finding was that N100/P200 potentials could be elicited. Spoor et al (1971) showed that N100 amplitudes were larger for intensity changes of continuous stimuli compared to tone bursts. Both Jerger and Jerger (1971) and Harris et al (2007) showed a significant relationship between N100/P200 amplitude and the magnitude of intensity change.…”

“…It can be evoked by almost any tran sient sounds, such as clicks, noise bursts, tonebursts and speech elements. It is also elicited by abrupt changes in the loudness, pitch, qual ity or perceived point of origin of continuous sounds [17][18][19][20][21][22], Audiometrically, N1-P2 is usually recorded by averaging over tonebursts presented regularly at about 1/s-l/ 2 s. with a vertex-mastoid derivation.…”

Some properties and applications of the N1-P2 complex (100-200 ms latency) are reviewed. N1-P2 is currently the auditory-evoked potential (AEP) of choice for estimating the pure-tone audiogram in certain subjects for whom a frequency-specific, non-behavioural measure is required. It is accurate in passively cooperative and alert older children and adults. Although generally underutilized, it is an excellent tool for assessment of functional hearing loss, and in medicolegal and industrial injury compensation claimants. Successful use of N1-P2 requires substantial tester training and skill, as well as carefully designed and efficient measurement protocols. N1-P2 reflects conscious detection of any discrete change in any subjective dimension of the auditory environment. In principle, it could be used to measure almost any threshold of discriminable change, such as in pitch, loudness, quality and source location. It is established as a physiologic correlate of phenomena such as the masking level difference. Thus, N1-P2 may have many applications as an ObjectiveÊº proxy for psychoacoustic measures that may be impractical in clinical subjects. Advances in dipole source localization and in auditory-evoked magnetic fields (AEMFs) have clarified the multiple, cortical origins of Nl and P2. These potentials are promising tools for the neuro-physiologic characterization of many disorders of central auditory processing and of speech and language development. They also may be useful in direct “functional imaging’ of specific brain regions. A wide variety of potential research and clinical applications of N1 and P2, and considerable value as part of an integrated, goal- directed AEP/AEMF measurement scheme, have yet to be fully realized.
