	'''Noise''' in the dungeon can wake [[sleep]]ing monsters. Monsters that hear a sound will generally wander toward it; if you get involved in a fight, monsters can come from all different directions to see what the fuss is about, potentially overwhelming you.		'''Noise''' in the dungeon can wake [[sleep]]ing monsters. Monsters that hear a sound will generally wander toward it; if you get involved in a fight, monsters can come from all different directions to see what the fuss is about, potentially overwhelming you.

			==Noise meter==
			Under default settings, the information panel in the top-right of the screen shows a noise meter. The colour and length of the bar indicates the maximum loudness of noise heard at the player's tile on that turn. Thus most player causes of noise will be reflected at their maximum loudness on the noise meter, but the noise meter will show noise centered a few tiles away from the player at the loudness the player heard, not the maximum loudness of the effect.

			The noise meter colours correspond to the following loudness values:
			*'''White: 0-6''': Noise at this loudness will not propagate far beyond the player's [[line of sight]]. Most melee and ranged attacks and low-level spells are in this category.
			*'''Yellow: 7-13''': Noise at this loudness will attract monsters from outside the player's [[line of sight]]. The most damaging melee and ranged attacks, shouting, and a number of mid-level spells are in this category.
			*'''Red: 14-29''': Loud noises that will awaken and attract monsters from a large portion of the current floor. Most explosive effects fall into this category.
			*'''Magenta: 30+''': The loudest noises in the dungeon, which will awaken virtually the entire floor. Only [[Shatter]], [[alarm traps]], and a few other particularly loud effects fall into this category.

	The following picture was generated by compiling the game with the option DEBUG_NOISE_PROPAGATION enabled. It shows which squares are affected by a simple shout. In this case, the intensity was 12 and the ambient noise was 0.

	~~Beware that this picture is based on the old noise model where noise propagates less far on diagonals. Now, the area would be approximately square.~~

-In most branches, this effect is minimal. Certain branches, however (the [[Tomb]] in particular), greatly amplify even the slightest noise.

+This effect is significant but not drastic. Shouts will not travel far in loud branches, whereas usually minor noises, such as attacking, may be sufficient to attract monsters in quiet branches.
