Sound Detection
The human ear is very sensitive.
Many times the question is not whether the sound can be heard, but if it can be filtered out of the background noise.
The following table gives the ranges, in hexes, at which various sounds may be heard 99, 90, and 40 percent of the time.
These Odds assume an average outdoor background noise level.
| Sound Detection Range (hexes) | |
|---|---|
| Sound | 99/90/40 |
| whisper | 4/ 5/ 6 |
| staged whisper | 6/ 7/ 8 |
| soft voice | 12/14/17 |
| twig crack | 24/29/39 |
| normal voice | 48/58/67 |
| loud voice | 96/115/134 |
| whistle | 134/161/188 |
| combat | 192/230/269 |
| shout | 163/184/227 |
| rockslide | 538/646/753 |
| bugle | 1076/1290/1500 |
| horses hard surf. | 134/ 161/ 188 |
| horses turf | 48/ 58/ 67 |
| footsteps hard | 48/ 58/ 67 |
| footsteps turf | 12/ 14/ 17 |
The following table gives modifications to the hearing range due to increased levels of background noise and other situations.
| Situation | Modifier |
|---|---|
| normal conversation (small group) | 1/2 range |
| normal conversation (large group) | 1/10 range |
| crowd at an event | 1/20 range |
| open air market | 1/10 range |
| through a door | 1/3 range |
| small group marching | 3/4 range |
| large group marching | 1/2 range |
| small group mounted | 1/4 range |
