The pedestal-plus-increment stimulus paradigm I described at the Society's San Diego meeting was administered to subjects with known sensory hearing loss. These subjects, who had histories of exposure to high-intensity noise while in military service, showed both marked high-frequency loss and recruitment when tested by conventional audiometric methods. The averaged auditory evoked potential (vertex potential) was measured at a low frequency where the subjects' auditory thresholds were near normal, and at a high frequency where their thresholds were approximately 50 dB above normal. At both of the pedestal levels employed, the functions relating log (N1−P2) to ΔI (the magnitude of the 150-msec increment) differed markedly. At the lower frequency, the functions resembled those obtained from normal subjects; at the higher frequency, increments as small as 1 dB yielded N1−P2 potentials of approximately 10 μV. At this higher frequency, the vertex potential was near its maximum for a 1-dB change in stimulus level, and increases in ΔI up to 12 dB resulted in only slight increases in N1−P2. These findings suggest that this method may prove useful in the detection of recruitment of loudness.
