Temporal modulation transfer functions trade completeness against measuring time

Evidence

On the other hand, the TMTF is comprehensive and results in multiple parameters that describe temporal acuity. Because temporal resolution is measured at multiple modulation rates, the TMTF provides a more complete picture of the temporal resolution of the ear. Further, the TMTF can be used to better pinpoint any sources of temporal processing difficulties because it contains more comprehensive information about temporal resolution than gap detection. However, measuring the TMTF is relatively time consuming and requires modulation detection thresholds to be measured at multiple modulation rates. — Jennifer Lentz, Psychoacoustics- Perception of Normal…, 1043
