40d:Noise
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.
Noisiness of various jobs
- Placing and removing buildings causes noise within 16 tiles. For example, placing a chair will cause a 33x33x33 cube of noise centered on the chair. Hopefully this will change in future versions.
- Firing siege engines also produces noise within 16 tiles.
- Mining and wood cutting causes noise within 8 tiles.[Verify]
- Jobs performed at workshops cause noise within 4 tiles.
- Eating has been observed to cause noise, although it is unknown exactly how much.
- Moving stuff in and out of stockpiles has been observed not to cause noise.
- More research is needed to determine how much noise other jobs cause.
Visualization
Noise radiates in the shape of a cube, 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
- Don't place buildings 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
- Put your bedrooms in a lower corner of your fortress, and make sure there are 4-tile buffers between beds and the centers of nearby workshops.
