| 100 Hz=0,17 α | 800 Hz=0,79 α |
| 125 Hz=0,20 α | 1000 Hz=0,87 α |
| 160 Hz=0,30 α | 1250 Hz=0,86 α |
| 200 Hz=0,34 α | 1600 Hz=0,84 α |
| 250 Hz=0,38 α | 2000 Hz=0,84 α |
| 315 Hz=0,47 α | 2500 Hz=0,83 α |
| 400 Hz=0,53 α | 3150 Hz=0,79 α |
| 500 Hz=0,65 α | 4000 Hz=0,76 α |
| 630 Hz=0,73 α | 5000 Hz=0,71 α |
