Conditions of exposure to vibration used in the study (the different combinations of root mean square (rms) acceleration magnitude and duration of exposure to a vibration with a frequency of 125 Hz produce the same 8 hour energy equivalent frequency weighted acceleration magnitude as calculated by the international standard ISO 5349 (1986))
| Unweighted acceleration magnitude (m/s2, rms) | Frequency weighted acceleration magnitude (m/s2, rms) | Exposure duration (min) | 8 Hour energy equivalent frequency weighted acceleration magnitude (m/s2, rms) |

| 62 | 7.75 | 15 | 1.4 |
| 88 | 11.0 | 7.5 | 1.4 |
| 125 | 15.6 | 3.75 | 1.4 |
| 176 | 22.0 | 1.88 | 1.4 |
