Higher-frequency auditory filters carry more intensity-difference information than the signal-centered filter

Evidence

Using these patterns, we can envision how the ear may be able to use information across frequency in order to determine which of the two tones is more intense than the other. The auditory filters higher in frequency contain much more information about the intensity difference than the one centered at the signal frequency. — Jennifer Lentz, Psychoacoustics- Perception of Normal…, 830
