| Method | Criterion | 4 Hz | 8 Hz | 16 Hz | 32 Hz | 64 Hz |
|---|---|---|---|---|---|---|
| MSO | Cell mean | 112° | 98° | 122° | 123° | 136° |
| 10th Percentile | 68° | 56° | 89° | 86° | 105° | |
| 90th Percentile | 160° | 138° | 206° | 174° | 161° | |
| IC | Cell mean | 137° | 99° | 113° | 143° | 125° |
| 10th Percentile | 55° | 45° | 72° | 98° | 85° | |
| 90th Percentile | 192° | 160° | 149° | 193° | 166° | |
| Psycho | 6 Subject mean | 37° | 40° | 62° | 83° | 115° |
| MEG | 7 Subject mean | 108° | 138° |
A dominance of the rising portions (0–180°) in the ongoing envelope is found throughout all methods and modulation frequencies. A detailed explanation is given in the main text.
IPD, interaural-phase difference; AM, amplitude modulation; MSO, medial superior olive; IC, inferior colliculus; Psycho, psychoacoustic; MEG, magneto-encephalography.
