Cross-correlation of the frequency-following response.
Frequency-following responses (FFRs) to a low-frequency stimulus in 16 normal-hearing human subjects were cross-correlated with the stimulus in an attempt to yield more easily recognizable FFRs at lower intensity levels and increase threshold sensitivity. Cross-correlation of these responses with the stimulus did not improve threshold sensitivity and latencies obtained from the cross-correlated FFRs showed more variability and were uniformly shorter than those of standard FFR measurement.
