40d:Noise
| This article is about an older version of DF. |
Certain jobs generate noise which disturbs nearby sleeping dwarves. Depending on a job's noise level and proximity, your dwarves could sleep "uneasily due to noise", "very uneasily due to noise", or be woken up by noise. These events will produce unhappy Template:Ls in varying degrees.
Neither walls nor doors will insulate dwarves from noise. Distance and how loud a job is are the only factors determining whether a dwarf's sleep will be disturbed.
Noise is produced when a noisy job is completed. Thoughts about noise do not appear until the sleeping dwarf has woken up.
Dwarves walking through a sleeping dwarf's room (even over his head) will not cause noise, which is important for Template:L.
Contrary to common belief based on earlier versions, Toady has stated that workshops do not currentlyv0.28.181.40d produce any noise. In fact, he states that "only digging, chopping, making fortifications, engraving walls and removing constructions" will make noise. Some of the information below refers to other kinds of noise - for the present version, those should be disregarded.
Noisiness of various jobs
It's important to remember that noise is created in all 3 dimensions, including across Template:Ls - see below for Template:L.
Short distances:
- Eating is believed to cause noise within 1 or 2 tiles; probably 1. It is unknown whether the noise radiates from the eating dwarf or his food.
Within 3-4 tiles:
- Template:L jobs produce sound 4 tiles away.
- It has been claimed that most other jobs cause noise within 2-4 tiles. More research is necessary to determine the specifics.
- An operating Template:L causes noise within at least 3 tiles.
Within 8 tiles:
- Template:L and Template:L
- Removing a Template:L
Within 16 tiles:
- Placing and removing Template:Ls causes noise within 16 tiles. For example, placing a chair will cause a 33x33x33 cube (or 35937 tiles) of noise centered on the chair. Hopefully this will change in future versions.
- Template:L has also been observed to wake dwarves up, which suggests that it causes noise within 16 tiles as well. Strangely, Template:L does not cause any noise at all -- which is just as well, considering dwarves will only spar in a Template:L, which is essentially a communal bedroom.
- Firing Template:Ls also produces noise within 16 tiles.
Non-noise actions:
- Jobs performed at Template:Ls have recently been confirmed by Toady to not cause any noise at all.
- Hauling, and taking from/placing in stockpiles
- Sparring
- Traffic
Visualization
Noise radiates across z-levels in the shape of a cube, in all 6 directions (north/south, east/west, and up/down), so noise that travels 4 tiles will generate noise in a 9x9 pattern on 9 successive floors. The noise radiates from the center of the noise-producing apparatus.

Noise in practice
- Try not to place Template:Ls like doors while your dwarves are asleep. Or if you do, make sure they are at least 16 tiles away from the nearest sleeping dwarf.
- Don't dig near the bedrooms when there are dwarves sleeping in them.
Designing in anticipation of noise
- A good way to start is to put all your bedrooms on level -9 or lower, so you don't have worry about noise from Template:L.
- If you anticipate there to be fighting in your Template:L, you should keep bedrooms away from there. (It is believed that fighting creates noise within 16 tiles, since it has the power to wake units up.)
- Alternately, you can deliberately place your barracks nearby, so that the combat can help wake up any sleeping warriors that should be helping. Remember that this comes at the cost of unhappy thoughts.
- Remember that Template:Ls, Template:Ls, and sleeping Template:L should also ideally be kept away from noise, in addition to standard and noble bedrooms.
Facilities that can be safely built around or above/below bedrooms and other sleeping facilities, to separate the area set aside for the "quiet zone", include anything that does not make noise...
- More bedrooms, jails, hospitals or barracks (Template:L housing)
- Template:Ls
- Hallway, stairs, ramps, etc.
- Template:L (or the magma equivalent) or reservoirs
- Template:L
- Template:Ls
- Template:Ls
- Template:Ls
- Template:L & other creature-holding areas
- Template:Ls
- Template:L
- Template:L (not within 1-2 tiles/levels, see above)
- Template:Ls Profiled solely to the dwarf who will sleep near them - a dwarf is either working, or sleeping, never both at once.
- Template:Ls built solely to aid in the collection of Template:L for Template:L elsewhere.
- Template:Ls built solely to allow collection of Template:Ls (an obscure choice, but legit).
- Workshops (such as a non-magma Template:L, etc) built solely for emergency Template:L use will only create noise if they are ever claimed, and then only for that short period.
