Abstract
The influence of stimulus intensity on the components of auditory evoked potentials was investigated at different levels of attention and task relevance in six healthy adult subjects. A negative component with a latency of 130 msec (N130) was produced by stimuli applied as targets or nontargets in a random sequence. The N130 amplitude had an inverse U-shaped relationship to stimulus intensity, with its maximum value at a stimulus intensity of 70 dB SL. The P300 latency showed a U-shaped relationship to stimulus intensity and obtained its minimum value at 70 dB. Thus, evoked-potential equivalents of cognitive auditory stimulus processing could be shown to be loudness driven and to have highest amplitudes or shortest latencies at a stimulus loudness of 70 dB SL.
