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 thoughts 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 bedroom design.

Contrary to common belief based on earlier versions, workshops do not currently produce any noise.

Due to a bug, dwarves only remember the last noise that they heard, so a sleeping dwarf exposed to a very loud noise followed by a quiet noise will only complain about having slept "uneasily due to noise".

Noisiness of various jobs[edit]

Unlike in the past, only 5 jobs are known to cause noise:

  • Digging - 8 tiles
  • Wood cutting - 8 tiles
  • Engraving - 4 tiles
  • Fortification carving - 4 tiles
  • Removing constructions - 8 tiles

Visualization[edit]

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 and reduces in intensity as it does so (within 25% of the range will awaken the dwarf, within 50% will be "very uneasily", and the rest will just be "uneasily").

Noise in practice[edit]

  • Don't dig near bedrooms when there are dwarves sleeping in them.
  • Smooth your bedrooms before placing the actual furniture.

Designing in anticipation of noise[edit]

  • 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 wood cutting.
  • Remember that jails, hospitals, and sleeping barracks 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.
