Detection is modeled as cross-correlating a stored supra-threshold template with the actual activity pattern.

Evidence

The final stage is an optimal detector, which calculates the cross correlation between a temporal representation of the signal at a supra-threshold level (template) with the respective actual activity pattern (Dau et al. 1997 ). — Dijk, Pim van, Physiology, Psychoacoustics and…, 3478
