Local SNR is computed per 23 ms one-ERB time-frequency unit

Evidence

The time-frequency (T-F) units thus created covered a fixed time length of 23 ms (i.e. 1024 samples) and a frequency band of 1 ERB width. In the final step to calculate the spectro-temporal SNR, the spectro-temporal power of each target signal was compared to the summed spectro-temporal power of the two masker signals with which it was combined in a single stimulus. — Dijk, Pim van, Physiology, Psychoacoustics and…, 1627
